Downpipe Feedback

[REZXPERT]

I'm interested in having a downpipe installed to gain some HP but i don't want to ramp up the noise factor. I understand replacing the downpipe will only eliminate the second cat and attach directly to the existing factory MS catback. Any suggestions for brand names? Is doing a custom pipe a good route to take?

[MPS]

i think CPE is the only one that won't set of engine light
and comes with CAT option
sound is not as loud as i wanted :complain

cpe actually offers an additional quad core muffler which without affecting the power increase significantly will help offer nearly all the performance gain of going with their dp, hi flow cat and 3" pipe without disturbing surrounding communities when you drive by lol.

I'd recommend the cpe tbe with hi flow cat, 12" muffler and additional quad core muffler

[REZXPERT]

i notice the cp-e dp is 3". the stock MS3 exhaust is 2.25"(?... i think). despite the obvious performance gains, i don't want the entire CBE simply b/c of noise. my last 3 had a complete catback + high flow cat (&headers) ..adding 2 huge resonators did jack shit. anyways, if i simply go with the dp + high flow cat, will the fitment be okay? sorry if i'm overlooking the obvious. thanks for the info.

First, your avatar is kinda creepy. Second, the stock DP starts off at 2.25 but increases to 2.5 later on.

I am confused as to what you are after, if you don't want any more noise leave it as is. If you want just a little noise with no real power gain, spend the $900 or so on the Mazdaspeed CBE. If you want a big jump in power without too, too much noise get the full CPE TBE system with the extra quad core muffler

Does anybody have a soundclip of the CP-E turbo-back system, with the 12" oval muffler, the high flow cat and the extra quad core muffler ?

I really dont want to be too loud but I want power. Just need to figure out how it sounds with or without that extra quad muffler..

Thanks.

[REZXPERT]

+1. quad muffler aka resonator, right? i had two resonators installed on my previous 3 (non Speed) but it was still too loud. don't mind a growl, but nothing stupid like rice rockets runnin straight pipes w/o cats. my goal is to make my MS3 faster but keep it "sleeperish". i hear CP-E's tbe isn't crazy loud but that's a personal call, i guess.

One thing I'd like to see is, if you have it, a pic of the rear of your Speed with stock exhaust from left or right, and then a pic with the CP-E from the same angle. I like how the stock tip sits right now...kinda under and I like that. I dont want a CBE that makes the tip go to far out of the car...like my Corksport on my 06.

you can have it mounted in more if you like... i got mine in more than the way it comes from cpe, but out slightly more than stock... would have gone stock if i could do it again

CPE all the way!!!!
with the HIGHFLOW cat, sounds perfect to me, about 20% louder than stock.
And I gained some power and torque
I should host a video someday...

Got my stuff yesterday. CP-E Full turboback with high flow cat and 12"muffler and Prosport Premium boost gauge. All taxes and shipping included (went to pick it up myself in the US) for 1495$CAN. Not bad.

full tbe or just the dp with oem cbe?

[REZXPERT]

have you heard COBB's CBE? doesn't sound anymore impressive than CP-E, IMO, so what i'm sayin is i'm not biting the COBB bullet ..... at least not this time!

well why would you when you've got a good tbe? cpe engine mangement may not be a good idea, but their dp is good

[wildchild_MS3]

dp with high flow cat + oem cbe
next upgrade will be the COBB AP and the Full TBE.

[RX9]

will the stock CBE rust after a while? the CP-E's sounds really nice.

[Big Dad]

Which is the best downpipe for the Speed 3, CPE, Turbo XS, Corksport, or wait for the Cobb. I plan on only getting the downpipe and high flow cat and leaving the rest of the exhaust stock. Does anybody have any feedback or experience with these products?

I think CPE DP is the way to go... PM MPS for some info as he might have an extra new one around

[wildchild_MS3]

From what I heard, don't touch CORKSPORT or mazdaspeed brand. (soldering is bad and will not last long)
CP-E is really a nice quality product. And the fiting is 100% accurate.
turboXS, I don't really know and as for COBB, no doubt this will be a great part too.
I have the CPE and no rust yet (made from quality SS)
So I think CP-E is the way to go too

[Big Dad]

Thanks for the response guys. I was suprised to see that not many people are responding. I guess not many people have moded downpipes in TO?

I'm a little hesitant buying from the states with duty charges etc.. I did get a reasonable quote for shipping from them though :)

You might want to wait b/c they announced on M3F that they are in the process of updating the DP with a cast bellmouth:

I doubt it. It sounds as if the GB is to clear out the old stock, before the new ones come in.

[CanadaGTO]

No they are not...... Hence why they are trying to get rid of "old" stock.

[Pilzz]

Either way the CPE units are good old or new. They cost so much but you pay for what you get. I have not had a single CEL with the DP on since I got it.

[mleblond]

might as well wait....it's only 40$ off anyways...any local sponsors sell these in Canada? I hate the brokerage fees...just so I know where to get it...thnaks

I agree with you, you get what you pay for! CPE is the best
my 2¢

[Fobio]

that casting does look sweet...but even @ $615 + shipping/duty, we're talking $700+ for a DP...I have no experience with this part, so I'm guessing the quality of the piece and the hp/tq gains must justify its price...

yeah...plus keep in mind, the CPE piece replaces both the traditional downpipe & midpipe that you would have to buy separately from other manufacturers.

[mleblond]

also keep in mind that GB saves on the DP but if you buy the full turbo-back system at regular price your savings are the same... So I really don't save anything from buying from this GB if I want the full turbo back system...

[SpeedBaby]

Catted?

Which vendor on this board sells them?

im not a vendor, but i have previously ran a few GBs for members here for CPE stuff. i can set up another order with them if anyone's interested.

price: same as advertised on cp-e website and this includes shipping, customs etc..

pm me if interested as i rarely follow the threads anymore.

[Fobio]

I understand now that the CP-E piece replaces the DP and MP. And of course, there's allhope w/ the TurboXS + Vibrant option...so I'm, trying to weigh out the costs of each.

Anyway, when they say the CP-E is a bolt-on, there's no welding involved? So it can bolt right to the stock exhaust?

Since I've also read that the majority of gains in a TBE is the DP/MP anyway, how much LESS gains would be had if we went with just CP-E DP/MP + stock exhaust? Cuz if at ~$800 for the DP for 90% of full TBE gains vs ~$1100 for full TBE, then I'd go with the DP...

Answer my own..

Apparently 2-4 HP difference between using stock cat-back and CPE DP vs. full TBE.. Also, the CPE DP is good for stage 2 using the AP. So I'm sold!

[Fobio]

can we start up a new GI/GB thread for this?

so we can leave this thread on topic.

[mleblond]

I am getting mine thru speedbaby end of month Catback + DP :)

[Fobio]

it'd appear that the CP-E DP is the way to go for the moment, and it seems no one's gonna wait around for Cobb...

wouldn't it be a nice surprise that the AP is released with the rest of the goodies?

I guess a GB/GI isn't necessary if Speedbaby is gonna do website price, all inclusive anyway...is there a min # req'd?

[Unoriginalusername]

whys the price so much better for the cpe now vs. in the summer?

GB price is sorta cost. just saving on the shipping and customs is more than enough for me :) And no minimum order from what I understand. Not sure either if the DP will be the new version or not but I don't think it matters much for us.

It's not really....just RPM trying to sell out his DP in a group by before they release the new version. You save 40$ on the DP but if you want the Cat-back too then your not saving anything...as they charge you more for the cat-back alone vs both together...

[Big Dad]

Speedbaby got me the updated CPE downpipe with the new cast belmouth for more midrange. Trouble is that I wont be able to afford to put it on for a month!

[RX9]

alright, do we have a GB now or what?

[alhope34]

I'd personally like to get the CPE more myself, but my bank account for mods is very limited and as so, so was my choice. Brand new TurboXS DP is $325 plus tax through pat. I got mine used off Vince. Around fall time when I get the money, I will get the Vibrant, which includes a high-flow cat in the MP section. In total, it is about $500 cheaper than the CPE full turbo-back, and will also get me 3" the whole way just like the CPE.

The downside to the TXS DP is that it's not catted (remember, you keep the cat in the MP section). But because there's no cat, the O2 sensors have no cat between them anymore, which could throw CELs. I posted on M3F a couple days ago, one guy said he's been running the TXS DP for a few months and no CEL, another member for one month with no CEL, so it's looking good. I'll tell you guys if I like it when I get it installed Wednesday. I hope it makes the rest of the stock exhaust louder. =)

[Fobio]

Hey Allan...hopefully, you'll post some of your videos with the DP so we can hear a sample!

Unfortunately, I can not go with a FULL TBE as it'll likely be too loud...I'M IN NO WAY KNOCKING ANYONE"S SET-UP...in fact, chalk me up as being jealous that I can't go with a louder exhaust.

BUT...I'm not about to give up the potent gains of a DP, therefore, MY GOAL is to find a combo that will not throw CEL (guess that means catted DP?) and relatively the same loudness as stock...

droning is also bad, but I guess it's all personal preference like Pat has said, so I guess a search for an overriding opinon is difficult at best...

Problem is, I've never heard someone' else's MS3, PERIOD! with or without aftermarket exhaust...guess that's a good reason for me to hit a meet...

[CanadaGTO]

Keep asking alhope34 how his is doing over time, he's the closest setup to what you want, Upgraded DP with stock exhaust. I doubt you'll find too many others right now, as I think all who got the CP-E DP got the CAT back as well.

I've not thrown a CEL yet after 5 days, but it may come eventually.... Not sure about alhope34 yet, but he only got it installed yesterday.

[wildchild_MS3]

Fobio, I have a video sample of only the catted cpe DP (my actual setup)
If you want to watch it, go to: http://turbohatch.monchar.com/
scroll down the page a little bit and you will see 3 vidéos.
This website is in french but if you want to see video, who care? :)

With the DP it's not too loud at all.
