Been looking around a little bit and it doesn't look like anybody makes an off the shelf setup for a rc sb, so I guess it'll have to be a custom setup. I had Flowmasters on my Cobra and loved the sound of them on that car, so I may have to go that way again.

 

When you say exhaust system what're you planning on? Headers? Or from the manifold back? or from the catalytic converter back?

Check out flowmaster 10s too if you want something on the louder side. Or some cherry bomb glass packs.

 

I have dual flowmaster 40's on mine and love the sound of them

 

Going from the cat back.

 

Ive got straight pipes with 5.5 inch by 12 inch tips and it sounds awesome just cant get on it hard in town.

 

I have a flowmaster 40 exhaust single in dual out y pipe, sounds great, has a nice deep tone to it.
