downpipe question

[clos561]

Is it easy to install a downpipe? I was checking out the downpipe thatis on cp-e.com soudns good and they claim 30hp 40 tq gains with the downpipe and catback exhaust. I am jsutcurious if it is possible to easily removethe downpipe fordealer visits......i dont have alift but my friend works at acura and he would help me install and remove if i needed to.....please help me ifyou have experience with partslike this

If you've got a lift, have decent hand tools, and have some experience turning wrenches, then you should have no problem installing or removing our downpipe. Truth be told, the hardest part is removing all the stock stuff: Heat shields, brackets, braces, oxygen sensor, etc. It adds up and is a pain. I would imagine with a lift, good tools, and an extra helper one can swap downpipes in about three hours. The first time will probably take a little longer as you learn the procedure however.

The single most important piece of advice I could give you however is to read the instructions before you do ANYTHING. Feel free to give us a call or PM me if you have anymore questions!

i will...i heard the video on the site but it onlyplayed once.....it was lovely i am now planning on getting the downpipe and then the exhaust......im not sureif the stock exhaust hooks up to the upgraded downpipe if not..i wil save and buy both at once....buti want to get a bov and cai b4 i get those and im sure its probably best to dothose first..? correct me if im wrong......i wil call inthe future when i make the order and if i need help understanding the installation....

I just asked out website administrator to check out the videos. If there is a problem on our end, he should have it taken care of shortly.

We actually made some changes to the downpipe and catback, which allows the end user to mix and match stock equipment with cp-e parts. In other words, if you'd like to buy the downpipe now and hook it up to the stock catback, then you're more than welcome to do so. The same can be said for our catback and the stock downpipe.

As far as which to do first, I personally love the sounds our intake makes. You can really hear the turbo even without an aftermarket BOV. It really doesn't matter which you do first, but you'll easily pick up the most power from the downpipe.

Wait. Cool that the parts interchange with stock but if I replace my downpipe with a CP-E piece it is going to flange up to a 2.5" pipe. What happens when I replace the CBE and add high flow cat (3")? Sounds like I would have a bottleneck in the exhaust still.

You're absolutely right, you will still have a bottleneck. Originally, we weren't going to offer the option to buy the kit in pieces for this very reason. But some people understand this and still get one or the other sperately. It really comes down to what you want out of the car.

for me the exhaust is next. I understand what you just said but please clarify this- if I buy the down pipe and the cat back at the same time to install all together, is there still a bottle neck?

Or will the restriction only be present when system is purchased separately?

You'll have a bottleneck no matter what. Either in the stock cat, or the flanges on the CP-E pieces that flange to to the stock cat location with a 2.5" flange

Thanks Jordan.

No, maestro, our turbo back exhaust system is 3" all the way through, with 3" flanges. Being a full 3" exhaust system, THERE ARE NO BOTTLENECKS. We don't use 2.5" flanges on this exhaust system, but the catback and downpipe will bolt up to the stock exhaust. BUT, like meha11 said, if you bolt either of the two cp-e exhaust pieces to the stock exhaust, THEN there will be a bottlneck because of the diameter mismatch.

Does any of this make sense, or should we put together a FAQ page on our website to make this clearer for people? Or moderators, can we put a sticky up?

Even though I understand this fully, I think you need to put together a FAQ because it seems alot of people are asking this question on this forum and others as well.

Then it will be done (drive)

Question for cp-e on your webpage for the cat back exhaust it says "Our attention to detail paid off when we visited the dyno. The cp-e turbo back on MS3 gained about 30 horsepower and 40 lb/ft of torque to the wheels compared to the stock system."

Then for the downpipe it says "When paired with our new cp-e cat back exhaust system, the full cp-e turbo back system on MS3 gained about 30 horsepower and 40 lb/ft of torque to the wheels compared to the stock system."

Can you clarify the HP and Tq numbers for me between the two?

Thanks,

IIRC, the complete turboback showed a gain of about 30whp and 40wtq compared to stock. CP-E was not able to dyno the parts separately.

I have already installed the BOV and CP-E CAI and awaiting the shippment of my turbo back exhaust. If you ask me, I would suggest waiting to save alittle more and buy the complete 3" turbo back exhaust. As is stands now, stock we have two cats and that my friend is a big detrement. I have decided to go with the high flow cat due to emissions and the law...lol But, this item will be installed with no hesitation but of course with a professional mazda mechanic.

MadOzodi has it right (yes)

I'm sorry it's confusing, but the dyno results reflect the gains one can expect from our full turboback exhaust system, which includes both the catback and the downpipe. When we originally dyno'd the two products we hadn't changed our flange design which allows both of our exhaust components to be bolted onto the stock exhaust. So at the time we had no choice but to dyno the car with the full turboback.

We're working on a FAQ for the turboback with should be on the website in the next few days. This should help clear up some of the confusion. Until then, feel free to fire away with your questions!

Thanks Jordan, no worries I'm going to go with the full system anyway.

Peace

yea i want to buy the downpipe and the cp-e exhaust at the sme time...but soon i wil buy cai and bov

Excellent, I'm clear on this now. Different flange size. I found your other comment also, in different thread;

The cp-e downpipe replaces both factory cats with either one high flow cat, or none at all (off-road use only!). So the entire exhaust section that contains the catalytic converters (from the turbo outlet to the first catback flange) gets replaced.

No problems with ID of the bigger flange having potential exhaust leaks bolting to a smaller flange? Is the stock exhaust bigger than I think (2.5")??

I can't believe I'm confussed by a flange!?
