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.

 

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

 

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.

 

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

 

$435 shipped.

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...

 

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

 

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.

 

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.

 

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

 

he's from canada, prolly will be 600.oo canadian dollars

 

What is diameter of a b-pipe?

 

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

 

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?

 

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.

 

Is the stainless necessary or only for looks?

 

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?

 

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

 

What is a mandrel bend??

 

it's where the bend is round and not crushed


mandrel

 

...like their springs.

 

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

 

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....

 

Good one!

 

you want ss beacuse if you live by the beach or a snowy area all of that salt is a nightmare on no ss parts.
