yea stay away from magnaflow and flowmasters, SLP are pretty nice and borla as well (i have the slp and i love them) exhaust systems are a waste tho cause they really dont add to much so stick to mufflers and throw on some tips, and u mine as well go with headers, if u want loud u could do straight pipes with a res delete, will sound a bit raspy but i personally like it, for headers most ppl do SSAC cause there cheap and get the job done, but if money is not a issue slp headers are pretty nice
