i have a 95 lt1 camaro bored to a 383 stroker. im looking to buy new headers for it and put a new exhaust on. for exhaust i was wanting to go with a borla race muffler but id have to custom build the system. has anyone done something like this befor or have any options for that? and also with heads i would like to know if anyone would know what would be the best. i was looking at pacesetter ones and offroad y-pipe. do they fit good and perform good? also i was wondering if 1 3/4 inch tubeing would be the best size right now. i dont have the most experience with all this but im learning as i go. thanks in advance for you help.
