mid pipe ?
03 GT, Ive already got a Flowmaster A/T cat back and im a little worried that a Mac off-road H-pipe will make it to loud so I was gonna go with a Mac h-pipe with cats(hi-flow :rolleyes: ) will I need mils for this or will my puter not see these cats as hi-flow? Cause I know with a off-road H you need the mils. cause there aint no cats. Thank you and Happy Holidays :)

you may or may not need them. If your check engine light comes on afterward then you will.

You shouldn't need them, never seen a case where someone had to use them with cats before. Only O/R mid-pipes have this problem.

do either of you have headers?? the tone of the exhaust got much deeper, they are not long tubes, but it did get a little quieter, yes. It's hard to explain, but everything rattles more cuz of the deep tone, but it's definitly less audible.
|
not on this car i dont but on my other ones i have. long tubes make them louder, not sure how its makes your quieter? thats kinda weird.
|
I've heard that shorties typically make them a little quieter, whereas LT's will make them a bit louder. That is kinda weird though.
