HELP HELP W Exhaust & Mufflers
Can anyone tell me? A cat back system is it worth the $$$ ? does it really help? what about just changing to a performance muffler? an what kind does a person get ? I dont want a lot of noise, so many 4cly sound like a dive bombing cessna airplane or a banging tin can.... or with the newer cars like this is there any gain with a exhaust system?. like what you used to get from the good old days when duel exhaust really did somthing for power & MPG. It seems to me as long as the cat is still there, that there will always be back pressure, no matter what muffler you use? am I way off here or ???
