Turbo Question
 

I recently got a 2.5" perrin catback with an invidia catless resonated front pipe perrin overpipe and revworks uel header with ecutek tune. My question is, is it still possible to install a turbo with the 2.5" catback and frontpipe or will there not be enough flow? My guess is that it just won't generate the power a 3" would.

its good

Since you already have the 2.5" parts I would run them until it looks like they are restricting power. My guess is that you can get pretty far on the 2.5" stuff.

How much hp are you looking for?

i ran my turbo with the complete stock exhaust for a while and it worked fine. not optimal but still fast as hell.
