I have a summit racing offroad h pipe with flowmaster 40 axelback exhaust and it sounds great on low rpms but at about 2,200 rpms it sounds HORRIBLE. It rattles really bad, sounds like a lawn mower and after about 3,000 rpms it clears back up. But about 2,200 to 3,000 it sounds horrible

I thought it could be a exhaust leak but I had a shop check it out and they said it was all ok. Is it just theese mufflers with the Hpipe just sound bad together?

Around town it sounds really loud and deep exactly how I want it to sound but if I get on it and accelerate fast it's the worst sounding car I've ever ridden in.

Any ideas before I try a new set of mufflers? I hate to get rid of my flows the car just sounds PERFECT up to 2,200 rpms..
