Exhaust Parts
I have a set of CPR(Custom Performance Racing) 1 7/8" longtubes going into 3.5" collectors for Highports on a 351w based motor. The rest of the exhaust is 3.5" flowtubes into 3.5" Schoenfeld outlaw mufflers and 3.5" turndowns. Had this setup on a 421" sbf with Highports in a foxbody. Fit great...
