i had rear cats cut off and i have two chamber flowmaster mufflers with resonate delete tips it sounded good other than the loud drone at around 2200 rpms. not to loud but noticable.i couldnt help myself being a mustang owner also with off road x pipes and one with off road h pipe i gutted front convertors to see what it sounded like. i love the sound when reving car up in park it seems to have a little more of a throaty sound to it now i have had alot of compliments. i just wish there was a way to keep the same loudness and get rid of the resonating sound at that certain rpm.i dont like that even though my wife loves that sound she rides around trying to make it sound like that.lol. i really would like to put headers on it but i just cant afford to spend 1800 dollars on exhaust system. is there any alternative to headers and that high cost like ordering long tubes or short tubes for a cobra mustang. i really just need headers cheap i can have custom exhaust pipe built for ther car. does dr or kooks offer there longtubes cheaper in a non ceramic coating????????????????
