Hey guys,
I just bought a 08 SS with stage 5 cam, HSV headers, twin 3 inch exhaust with no cats, rear mufflers and I think a centre muffler. Sounds great at idle but it drones a lot plus I want it to sound meaner and more old school V8. It also has 500hp+ roller rockers, OTR CAI, stall converter and has motor/gearbox tune @ 387rwkws. (All work done at Walkenshaw in Newcastle)
I want to put 200 hi flow cats to keep the cops at bay and I was told to remove the rear mufflers and install straight pipes or J pipes. Should I remove the centre muffler as Well?
Is this the way to go? Any other recommendations will be appreciated.
PS it backfires in between gear changes when flat foot.
