On avalonracing.net i think, it says that a stillen intermediate pipe adds 25 hp for only $224.10. What is this and does it give you 25 hp no matter what, or do you need to have other mods for it to work well? thanks, i'm always looking for the least expensive mod for the hp.

 

If ur talking about a B-Pipe, I've got one. I don't know about the gains, since I've not dyno or track tested the car since the install.
But, my "***-dyno-metter" claims few gains if any.

Any muffler shop should be able to make one for less than $100. It's just bent exhaust tubbing. Nothing fancy.
Keep in mind that this, along with an aftermarket muffler will make your car loud.

 

Ok thanks, if that's what it is, then I'll keep my distance.

 

those horsepower claims are false.. you'd be lucky to see 1 or 2 hp out of it.. nothing youll ever notice

 

I noted over a .15 drop in et and a gain of over 1mph with the addition of my B-pipe. 60 foots were all in the 2.3 range and the conditions were nearly the same. 25hp? Nope. I'd say more like 5fwhp and 5 fwtq.

I have a Stillen B and if you use it along with a Y you'll free up the exhaust a great deal. If you saw the stock B pipe, theres crimps and bends all over it, very restrictive. If you use the stock muffler and put a tip on it like me, the sound is quite interesting. Its not ricey, buts got a deeper and meatier tone to it. I like it.

 

hehe 25 hp?? I wish.. I'd be selling more B pipes! a butt dyno would noticed a small difference... less than 6 hp above 4000 rpm.
