will it make much of a sound difference just to put a cat-back system on the cobra or do i need to save until i can do headers and a mid pipe also. and does anyone kno where i can get a decent sounding exhaust that i can install myself for under $400?
Depends on what you get. Some catbacks are louder than others, some just louder than stock.
It really wont get too loud untill you swap the midpipe out though, thats were all the sound is at. A catless midpipe will be the loudest. A catted mid should open the sound up a little as long as there are only 2 cats, not 4 or whatever is stock.
Headers change tone moreso than make noise. Yeah, it will turn the volume up a little bit, but not as much as a midpipe/catback.
so if i can only afford one, would a cat-back or mid-pipe offer the best sound gains? but actually it looks like i could afford the mac offroad h-pipe and the mac cat-back. would that be a decent set-up? shorty or regular offroad h-pipe?
do these system's just use hangers and bolts or do i need to have someone else install it. cuz the flowmasters system i have on my truck had to be welded in.
