I was just wondering about what size I could or should get for my 88 GXL??? I've heard people talk about 2.5 inch exhausts but I also hear people talking about how rx7s are very exhaust restrictive cars so I was wondering what would be the best size to get??

 

2.5'

 

oh and if there is more than one pipe, 2'

IE: Header, Collector, Dual-Catback
Dual 2~>2.5~>Dual 2

 

I wanted to get a custom made 2.5 exhaust and I still want to get headers.. How loud would that be and how much power could I get out of that??? What would I be able to beat??
thx

 

I personally went with 2.25 Mandrel Bent Stainless Steele Bruleen Exhaust with RB Header.
