I'm totally new to this site, so forgive me if I am posting in the wrong area.
Anyway, in 2010 I bought a new 2010 grabber blue Mustang GT. I originally installed Pype Bombs exhaust (axle back). Was originally pleased, but they always sounded as if they gave a rattle and I could even tell it in the throttle. I took it back to Midas where I had it installed and they never could get it right. I finally determined after riding with this thing for nearly 3 years that it was just expansion of the metal. Other than that, they sounded ok, other than a little drone around 1800-2200 rpm's. But I changed those out a few weeks ago for Super 44's. The exhaust sounds fairly deep, and growls decently when you get on it, but honestly, it's not quite what I want either and it's welded in. So I have wasted hundreds of dollars in exhaust and still don't have what I want. But these two videos describe the sound I want. Something that will be obvious, but basically only upon start-up and throttle down. Is there anything I can get that will be relatively cheap?? I am tired of wasting money and want it to work. I have considered the SLP Loudmouths, but can they be installed after these others have been welded in? Sorry for my ignorance, but I'm just learning about this stuff and a late newcomer to the muscle car thing, but enjoy my car other than that! Any help is appreciated.
