I'm getting a s/s y-pipe and I am curious of its gains. Are the gains noticable with stock airbox intake? I will be removing the intake and adding a CAI in Jan, /w possiblity of a Pop Charger.

 

get the CAI first, then worry about the exhaust.
by that time, warpspeed should have their stuff completed and dyno'd..
besides that, you can buy a CAI AND a WSP Y for almost the same price as the cattman S/S y. how's that for savin money?

 

Hmm, I already have the y-pipe, and the CAI will be next month. I'm getting the parts for some work I've done for Cattman. I was curious how much improvement I'd see I don't think the y has any problems /w scraping and all that for my engine, only the SE engines (VE?) cause they're all big and blocky
