I have 2 hooker aerochamber mufflers for sale, 2 for $100.00, u pay shipping, I only had them on for one week and I bought a magnaflow cat-back instead, its just as loud as flowmaster 40's but without that raspy noise.

Mufflers is 2.25inches offset inlet and 2.25inches center outlet.

Default Magnaflow on 2008 GXP

Sorry to jump on this thread but looking for someone else that has tried the magnaflows on a 2008 GXP. Quoted my other post, sorry if that offends anyone.
"Has anyone installed the magnaflow exhaust p/n 16726 on a 2008 GXP? If so what size bolt and nut should I use? There is studs on the OEM resonator side now which is different than the previous years. I wonder if there is any other differences. i.e. hanger location, bends, clearance, etc.?"
Thanks for your help,
