nope, the most restrictive part in the stock exhaust setup is the y-pipe due to pre cats etc. you would get some gains with a decent b-pipe but results would be better with a y-pipe

 

It'll open it up........but it's gona be like having a cat-back. You can do it, of course but it depends on what you want.

The WHOLE exhaust system being aftermarket can cost easily over $500. Is it worth it to you?? Are you planning on boosting your motor? Do you want just sound or 5hp gain?

 

i want the gain. im not planning for turbo or supercharger. i want all motor power. i was jus checking cause i can get the b-pipe done in shop for cheap so i was like whats the differenece in power w/o y-pipe but would it give me atleast 5hp@wheels like its gonna matter that much thnx guyz

 

Fix your sig, please. It's too wide. The widest it can be is 550 pixels.

 

"pipe for pipe" speaking..get the y pipe before the b pipe. the combination wont hurt either
i heard gain of around 15+ hp at the wheels!! for the bpipe y pipe combination
a catback exhaust will give maybe 5 hp on its own..

 

There is a nasty kink in the b-pipe that gets down toabout 1" diameter inside, guess that's how we get our loer rpm torque.

Yes but we all already know those numbers aren't corrected. If they were the y-pipe gain would be around 13-15hp and the b-pipe gain would be around 5hp or so.

 

So a Y-pipe gain should be around what exactly?? B/c if there not gonna be 13-15hp, how much less are we talkin here?
Would the addition of a B-pipe help out at all?

 

The Y pipe gives you the most gains.

 

i guess i should save money and buy them @ the same time
