I've spent too much money on an exhaust system, that I am still not happy with. Boomy at about 1500-1800rpm, and overall a bit too loud for my neighbourhood. I am after a bit of advice on how to get rid of the boom, and still have a decent high performance system.
My specs are as follows:
VS commy with 5L V8 - stock bottom end, mild Wade cam, roller rockers, 70mm throttle body, Greenfoam tune.
Pacemaker tri-Y extractors into 2.5" twin system
Twin 3" Magnaflow cats, with ends tapered to suit 2.5" system
H Section balance pipe
Twin 2.5" lukey turbo mufflers
Twin 2.5" hotdogs (short - only about 6-8" long) at the rear
Twin 2.5" s/steel tips
The cam and extractors understandably make the car a bit louder than stock.
It has been suggested that the cats are the problem, and I should go back to 2.5" cats. I have also thought about installing a Tru-X cross pipe instead of the H section balance pipe, and/or replacing the rear hotdogs with longer 2.5" resonators, or maybe merging the rear into a straight 3" pipe.
Before I spend anymore money, I would be interested in getting a few opinions from those in the know.
