What do you guys think the most powerful catback is ? I was thinking a courtesy b-pipe with a 2k1 muffler since of the backpressure bla bla bla thing. You guys have any other suggestions ?

 

Y pipe and Straight Pipe..

thats all you need buddy boy

 

Im talking from the cat- back...lol

 

waaaahhh? I CAN'T HEAR YOU

 

NOTHING FROM THE Y PIPE BACK.

 

argh.. You guys. i said a CAT BACK. I mean some metal and ****.

 

well do all straight pipes like what sx7r did..

 

Won't help much on a NA engine though.

 

This is all out of curiosity. I already have a catback as you can see.

 

sure it will.. free flow... like free balling

 

hahahaha FREE BALLIN'

 

straight pipes with resonator in place of cat.

 

Ahh guys im talking about Legal, and catback system. Thats why i said the courtesy B-pipe and 2k muffler. How is this setup ?

 

courtesy b-pipe sucks and 2k muffler is all in your mind, it's still not straight through. both are a waste.

 

Plus you are already illegal because of the Y pipe, so yu might as well go illegal.

 

I have both the Courtesy B-pipe and 5th gen muffler on my 97 and I'm happy with it. I installed the Y-pipe a week before the others and I noticed a significant gain from that. Adding the B-pipe and 5th gen muffler was about 60% as significant. I'm not sure if the muffler itself is what makes it so great, but I'm happy with the results. I can chirp going into 3rd gear with my stock 16's now and my driveability has improved. No loss on the low end and I get about 29 MPG on the average with mixed freeway/city and a few quick races per gas tank.

 

that's what i say, if your gonna get in trouble go all the way.

 

The Courtesy B-pipe was good for consistently lower .15 ets and a gain of 1mph under the same conditions as proved by 15 timeslips. When you can back up your opinion with facts come back and join us.

it sucks compared to a full catback, you have to buy that pesky o2 connector piece that is very restrictive, i'm saying that a full catback, or straight pipes is better.
why replace one restriction with another.

 

Have you seen "1/3there2/3togo" (Kirks) Setup ? He's the first guy with the dual exaust deal on his Max that I've seen ! It looks sweet.

I donno if that results in the loss of some power, but damn I'd like to have that setup.
