i want a new exhaust and im thinking either type one(2.5) or the thermal(3). But im dont kow if the thermal is too wide and i will lose power.

I have a jackson s/c so im thinking of gettign the thermal. What does everyone else think?

 

I would say stick with 2.5". You could see benifits of having a 3" if you swap out the pulley and boost more, and run more mods, but for a mild JRSC'd motor, 2.5" works just fine.

 

yes, 2.5 is more than adequate. supercharger isnt like a turbo to warrant running 3"

 

2.5 yes indeed.

 

i plan on running more boost real soon so you think i should just get the 3"?

 

I'd go with the 3", but if you still find yourself tossing over which one to get, send an IM to "RBoosted717".... He'll be able to help you out.

 

...3" ...even on a mid to high power NA car...

 

2.5''

 

3 in for FI
