Can anyone give me advice on what kind of mid pipes and cat back system work well with my 98? I have a few people tell me to get flowmaster 40's, delete the catalytic (all 4) straight pipes and put dumps right after the flowmasters. Will I loose or gain HP? I plan on putting a NX express nitrous oxide system later on with a JLT cold air intake.
Mac headers are the cheapest you'll find > go with a x-pipe with cats > it will keep you legal and cut down on the in cab motor noise !! > as for a cat-back SLP OR Mac cat back > don't put a crappy ME TOO FLOWmaster exhaust on your car > SLP IS THE BEST BUT IT"S ALSO THE MORE COSTLY . > I have a Mac cat back-on my car
