American Racing Header woes...
Hey all, its been ages since I posted... but.
In May I became a GT500 owner... since then I have installed American Racing Headers 1 3/4" primaries / 3" collector.
I also purchased both an on/off-road X-pipe. Now I've been through the following set-ups and haven't found something I'm happy with.
X-pipe with high-flow cats // Magnaflow catback (Piping and full mufflers) - Too quiet
Off-road X-pipe // Magnaflow catback (piping and mufflers) - Too quiet
Off-road X-pipe // Bassani race axle-backs - Too loud / Drone / Trumpetting
Off-road X-pipe // Corsa Sport Muffler - Ungodly rasp at 1800-2300 RPMS
X-pipe w/ High Flow cats // Corsa Sport Muffler - Somewhat raspy, but not quiet there.
So I decided to order an off-road H-pipe for the Headers and hopefully the H will take away most of the rasp......
Just wondering whos got what mufflers in their ARH long tube set up?
