I want to know if Y-pipe+straight pipe+b-pipe would show some nice gains. I just dont know if getting a straight pipe and b-pipe would be worth the money. I have 2k max 5spd with intake and y-pipe and plan to get RSB, UDP, B-pipe, and Straight pipe, hoping to hit mid 14's. Any other recommendations on good bolt-ons or ECU mod would be much appreciated...

Don't want to go FI or nitrous YET.

 

straight pipe wont really give much of anyhting, but the b-pipe certainly will. you said you already have the y-pipe, thats your biggest hp gainer, and then the UDP would help ya some too.

 

Here is the setup I got on fri. Its on a 2k2 but same for the 2k. Gives you all options so you can select how much or how little noise or performance you want.
