hey guys, im thinking about getting this exhaust kit for my Iroc
Summit Dual Exhaust Systems: SUM-CBJJ205 - summitracing.com

the pipe diameter is 2.25 and the headers primary tube diameter is 1 1/2, is this an ok kit for the price? and what would i be getting power-wise with this kit over stock?

i'd skip that and just make the custom exhaust we all make.

headmann 1 5/8" long tubes
headmann S-bends in 2.5"
summit brand H-pipe in 2.5"
sections of 2.5" pipe to any choice of mufflers then turndowns before rear axle

ok, but what would it do for me power wise?

more power, but who knows how much. if it's a stock motor maybe 15hp maybe less maybe more. this is a hi-flowing exhaust and not needed for a stock motor, perhaps a nice 3" catback would work better for you if you're staying with a 305 that is stock.

the engine is rebuilt, and has abour 100 miles on it, i got aftermarket MAF sensor and K&N air filters. i am planning on swapping it out for a 383 eventually. will it still be any good?

im referring to the summit kit just to let you know lol, im eventually gonna swap my 305 for a 383, would it still give me some good hp?

Depends on how much power you want out of it, with 1 1/2 primaries and 2 1/4 pipe you will be limited to 400 hp or so

im dropping in a chevy 400 anyway, so i'll be getting something else.
