Default S-trim fox - Which exhaust to buy?

Hey Guys,

I am debating whether to go with a 2.5" or 3" cat back exhaust for this car.

Motor is stock minus the GT-40 intake, 70mm TB, JBA headers, BBK catted 2.5" h-pipe, and 3:73 gears.

This car is driven on the street and I need to find a setup that will flow great and be drone free.

Any ideas?

Thanks!

Complete 2.5" system is fine...

What size headers do you have (primaries and collectors)? I would recommend 1-3/4" with 3" collector for a boosted application. If you are keeping cats best to have hi-flow performance ones otherwise they might be a choke point.

I have old school JBA shorty headers from the early 90's!

Room for improvement for a lowered, street car? perhaps!
