How much hp from a catted X?

[Screamin' Demon]

Alright I have my new PI intake on the car and need to get the exhaust freed up so how much will a catted X-pipe, say magnaflow net me rwhp wise? Im not going to do heads or cams for a long while so Im doing the boltons first. Any other recommended mods first?

I gained about 6RWHP and lost 4RWTQ with my catted SLP

I don't have dyno numbers but out of all my mods, the X pipe is the only one I'd buy again in a heartbeat. The rest I probably wouldn't buy.


Definately a noticable increase in power even though I don't believe in SOTP.

probably 5-8 rwhp
