What gains did you get from the b-pipe alone? I'm looking for more high end. How much did you pay? I'm thinking about the courtesy pipe. My current setup is intake, y-pipe.

that is pretty disappointing. Did you have the custom pipe made mandrel bent? Or just larger piping?

ZuM

 

gains aren't exactly drastic, but you gain some high end. i payed $170 for the courtesy but i had a hookup. it made may car louder big time, but maybe that's cuz i have a hollow cat.

 

Bah, if its not a that much of a difference. I would rather not have the noise.. =P Thanks for the responses guys.

A honest and true consist .1 drop in et and a gain of 1.5mph in the 1/4 mile. The Courtesy pipe is a great piece and it is fully mandrel bent. It is 2.5" OD and about 2.35" ID. More lowend torque punch is what I noticed about the pipe. I really couldn't tell a difference in topend power. Like I've said before, my 1/8th mile et and speed improved.

You're running a stock muffler also right? Hows the sound with the courtesy pipe? I like how my car doesn't attract any attention when I'm not on the throttle. How much did you pay?

ZuM

 

Yep, I've got the stock muffler teamed with the B-pipe and Y-pipe. Since the resonator is smaller, the Courtesy B-pipe is about 20% louder than the stock B-pipe. It was $180 from Courtesy.

Biggest gain I got was ground clearance. Another 3" to keep from scraping on medians & driveways.

Running w stock muffler and couldn't tell diff by "seat of pants" or g-force runs. I'm sure getting rid of the crimp has gotta help though. A bit louder too.

I had lots of noise after the initial install. Banging and what sounded like backflow resonance at various RPM's. A little bending & tightening did wonders.
