Is it really worth the money to get a comptech b-pipe with stock '03 mufflers.
Not looking for huge explanations. If someone can draw the pro's and con's, that would be great.

phipark

Pros - Gain maybe 3-4 hp and I believe a deeper exhaust tone
Cons - Paying $600 for the above.

Linner

No, its a waste of money, the gains you will see are minimal, if anything save the money and buy the rotors which are prob around the same price if not cheaper.

Linner

600$ for a b pipe? I thought it was around 250

BEETROOT

$435 shipped.

phipark

Well, we were both wrong. It's $450. Still a little too expensive for my tastes.

Already bought the rotors
Had some extra money to spend, but b-pipe seems to be a unreasonable expense.

Thanks for the info guys

I paid $425 installed at an Acura dealership. And it is worth it despite what some others have said. There may only be a slight 3-4 WHP gain for N/A cars, but it improves the drive-ability of car throughout the rev range. But it does make for more exhaust sounds, deeper and loader; a lot more aggressive sounding. For a S/C'd car, makes from 5-8 WHP.

im expecting my CT exhausts next tuesday, will get the B-pipe probably in a month. then afterwards its time for some headers...

BlueCLS6

with what cls6sp03 said. Very little difference N/A and a few ponies S/C'd. Turbo cars will see much more of a difference as less back pressure on the turbine frees up more boost. I probably got 15whp or so out of it. The sound also changed slightly, deeper and more girgly now, I like it. I got mine for $380 cash. There are pics here:

i dont think its worth getting the b pipe if your na, better to use the money on i/h or pullies

Allout

If NA, put the money into your headers first. That will be the best HP gain. Keep an eye out in the black market.

I like the sound too

I will let you know Friday....I am tracking my car for the first time since adding the b-pipe. My previous best (supercharged) was 13.67 @ 102.72. Looking to beat that.

scalbert

Correct, there will be little gained on an NA vehicle and a few on a SC'd car. What I would expect with the blown car is that boost will drop but power will go up. That drop in boost would allow you to go to a different pulley and bring the boost back up for even more power. I would expect nearly the same 15 WHP as the turbo.

You turbo guys have it a bit easier as your boost level is automatically compensated. We have to make mechanical changes.

Just FYI, on my last dyno session I lost over 1 PSI boost when I opened the cut out. I may only loss 0.5 PSI with just the B-Pipe. But add back in the 0.5 PSI and the inherent gains fromt he B-Pipe and that 15 WHP looks reasonable.

In other words, there is a B-Pipe in my near future.

BTW, if you're seriously considering a B-Pipe.. hold off for a few more days as we're working on getting special pricing for a "Comptech Sale". Seriously.. it will save you some bucks.

rezurex

will definitely wait for the sale junior, i have had only good experiences dealing with c-c-c

What is diameter of a b-pipe?

av6ent

Nevermind found it - 2.5" then 2" to the mufflers.

JaredGMS

Ok, so why not just go to a muffler shop and have them replace the cat-to-exhause piping in the same dimension?? Or go with a 2.5" "B-pipe" out to a 2.5" exhause...wouldn't it cost a HELL of a lot less?

scalbert

Many muffler shops don't always work with stainless and most cannot do mandrel bending. A shop that can do both would end up charging close to what Comptech does.

Seattle Cl-S

Is the stainless necessary or only for looks?

Seattle Cl-S

Nice time Flint. Good luck. BTW, why do I trap almost 2.5MPH faster in the 1/4? Was this time w/ your 19's?

scalbert

It resists corrosion unlike steel so it doesn't rust out in five years or so.

JaredGMS

What is a mandrel bend??

rbf351

it's where the bend is round and not crushed


mandrel

edgalang

...like their springs.

JaredGMS

Got it. Less abrupt turns equal less backpressure = more HP.....ok

Thanks

I didn't notice a drop in boost when I added my b-pipe

scalbert

Interesting and this will need further looking into. If you didn't see a loss then you are not moving enough to cause boost stacking. Or you have more back pressure up stream which would be the catalytic converter.

I know this may be hard, but try unbolting the catalitic converter and see if there is a drop in boost.

I expected and saw a drop in boost with the cut-out open. I would expect others to see a difference with a partial benefit to reduced exhaust back pressure.

cant you take off your stock y pipe and paint it? i am thinking about doing this since the stock one is just plain ugly. and getting a y pipe from comptech is not in my budget.

can anyone recommened a paint?

Shouldn't be too hard, just loud maybe....
