CT B-Pipe Update
Like some of you, I'm getting a little anxious about the availability of the CT b-pipe. Here's the latest as of 6/17/03:
I wasn't quoted a real price yet but I've been told that the b-pipe might be between $300 and $400, most likely less than $500. Also, all the parts are in house and are waiting to be assembled. When posing the question "will the b-pipe be available before the end of July" I was told "most likely so...".
I've been calling them about once a week for updates. I'd suggest that we all do the same.

- 2 1/2 inches in diameter
- About 4 foot long
- Has a resonator/muffler near the end where it bolts to the Cat
- The other end bolts to the two axle-back exhaust-mufflers
- 100 % SS

Mike B has mentioned that this mod is more for the S/Ced CL-S for N/A the gains are negligible
so save the $500 unless your S/C and even then gains are only like 5 hp for $500 = 1 HP for $100 :thumbdn:

Secondly, if the CT intake and headers are installed without the CT axle-back exhaust, the effective HP gain will be much less throughout the exhaust system. Installing the CT axle-back exhaust will uncork another 5-7 WHP because of the bigger diameter pipes and better flow through the muffles.
So it only makes sense if you increase the size of the b-pipe say from about 1 7/8" dia. to 2 1/4" dia. this will improve gas flow efficiency throughout the entire exhaust system (please note: not sure about exact stock and CT pipe dia. but I believe they're close). For non-SC'd engines, this could uncork another 2-5 WHP, maybe more. For SC'd engines, maybe another 5-10 WHP, maybe more. Keep in mind that the b-pipe is the longest exhaust component (about 6-7 ft. total length including the y portion of the pipe) and may be the biggest bottle neck.
Another thing to consider is that the CompTech prototype CL dynos (according to Nate) at around 325 WHP with i/sc/h/b-pipe/e/flywheel-clutch installed. On the CompTech website, they show 299 WHP for i/sc/h/e on the dyno chart. So where is that roughly 26 WHP coming from? Certainly not all the WHP gain is from the lightened flywheel and clutch assembly.
Even I'm speculating here, so we should wait for the dyno numbers from CompTech.

so is comptech telling us that our stock exhaust is actually really good for the NA setup and they are basically just making a SS cat-back system for the sake of it being SS?

exhaust maybe 1-3 HP b-pipe maybe 2-4 no way more than that from increasing pipe diameter you still have the cat restricting air flow remember. for the $500 for the b-pipe makes no sense at all IMO and Im a comptech buff...I think they are running out of mods for the Cl-S and they are still trying to get some money from the cl-S owners even if its not much gains
think about it even the Ice-box will give you more than the b-pipe...it would look nice but $500 is ridiculous dont you think

I believe this was due in part because of the accumulative affect of inaccurate information that was being disseminated on the forum that eventually caused a lot of confusion between customers (us) and CompTech Sales. The b-pipe at the time when Mike B made his claim was based on no facts only baseless speculation on his part and not that of the Tech dept. at CompTech - IMHO.

Interesting... But I don't think it would be worth the money for that kind of gain... Like Titand said... I rather have a muffler shop make a good pipe for me for like $250...

ok heres a good question im supercharged with everything including the flywheel upgrade.is 5hp gain at the wheels or at the crank?second only 5hp on a supercharged car?does anyone know?

Damn right. Cat-Backs are not rocket science. Once this B-pipe comes out, there's gonna be some sucker in town that gets it, and the other smart assholes(ME) asking to see it and having shop just recreate the design.
This pipe is pointless unless you have FI. Minus well take out the cat if you want some real power.

Question for you types1967 ... do you have any dynos numbers for your CL? If you have a similar setup, minus the only the b-pipe we might be able to get an idea of some numbers.

Oh... one thing I forgot to mention... I was handed a new CompTech CL 3.2 brochure last Thursday when I visited them. In it, they said the b-pipe would provide a slight change in exhaust note. When I was given a test ride in the prototype CL, the exhaust note was awesome, but not to load or obnoxious.
So I'd consider buying a CT b-pipe and exhaust combo because of the following reasons:
1) All SS
2) Between 8-12 WHP gained from the two exhaust componets ( still speculation, we don't really know yet - but if true... )
3) Awesome exhaust note
4) I'll probably install the SC within a year.
Besides, I feel like burning some $$$

So the point I've been trying to make is if CT's claim of almost 325 WHP on the dyno for their prototype CLS, where's the extra WHP coming from. Most certainly the b-pipe must be some percentage of that gain. But again, we can only speculate for now. Maybe when you get the b-pipe (assuming you would), you could provide some new dynos numbers.

just a side note, our stock b pipe is stainless.

the pipe is. the pre muffler, mufflers and hangers are not.

hmmm
I agree here. I have a Good Friend at the Muffler Shop. If this is all there is, I can get him to make me the same pipe for less than half the 400 that this thing will probably come in at.

I think Comptech is doing the old
220 whp stock +
32 whp headrs +
57 whp S/C +
5 whp exhaust +
10 whp b-pipe +
= 324 whp but we all know dyno does not work this way a little over 300 is more like it and thats max

so if are are all stock and just buy the b-pipe, are u guys saying that there is no point and it will be a total loss? W/o S/C and stock exhaust should i even consider it?? Will there be any changes in the stock exhaust note?

Get ready for some massive low end torque loss if you N/A guys are getting this. You need that extra low end power from an SC to compensate for this. There are countless 2.5" catbacks made for 3.0 V6 Accord, a lot of guys eventually sold their catbacks because the top end gain was not worth the low end torque loss. I sold my piece of shit 2.5" catback system because I was actually lagging behind stock Accords off the line! Anything below 3k RPM will cause a slowdown in exhaust gas flow rate because of the larger piping diameter. And YES, stock Honda/Acura Y-pipe is already stainless steel, it is just not polished with a shiny finish. Also with a larger b-pipe, prepare for a louder exhaust note. Those who thought just the Comptech mufflers were loud and had to use a quiet insert tip, scratch this off the list now.
And NO, the b-pipe is not the biggest bottleneck of the Honda/Acura V6's, it is the exhaust manifold. That's why the headers give so much gain over exhaust or intake mods.
