Got my 77 finally, runs awesome and all, had some crappy exhaust on it so i just cut it off and now im lookin through my options for exhaust. Its got a 350 in it so i know it can make some nice noise but i want somthin loud and growling, ya know? The guy who sold it to me mentioned i could get corvette headers or somthing and then just straight pipe it back, my guy who i buy my exhaust stuff from suggested dualing it with 3 inch pipes comming back to dual Encynerators, but i wanna get yalls opinion. Thanx!

 

Corvette headers probably would not fit - they're made for a Corvette, but no doubt you can find a good set of long tube headers that will fit a '77 - call or look at some of the big company web sites -- Hooker, MAC, Hurst. etc. Long tubes will do you much better (26 inch or more would be best), probably 1 1/2 inch diamter or 1 3/4 if you have a really modded motor.

Straight pipes with no mufflers, particularly if you have no cats, will be very loud. 3" dual pipes are also a bit too big: you can go too big with the pipes and over reduce backpressure.

I would think that a 2 1/2 inch dual piupe setup back to a pair of magnaflow mufflers would prodce a good sound, particularly with those headers. Magnaflow has various standard oval-body mufflers and you can go on their site and pick some.

 

buy the camaro headers. go to an exhuast shop and have them bend you some piper
Thats what id suggest
