Throughout the next year i will be building a camaro to do 12-13s sec on the 1/4 mile either by 383 or 350. since headers will be identical either way i need advice on the type of flow master exhaust i should get. I want to keep the car as a daily driver as well so i don't want to get obnoxiosly loud. A friend of mine suggested 3" pipe in and 2.5" dual outs would be adequate exhaust flow. On the other hand I'm not to sure what type of muffler i would want to get from flowmaster. any advice would be great thanks.

 

i would suggest a set of dyno dons headers which are 1 3/4 primaries with a 2.5 collector along with his y pipe and a good 3 inch catback would be good enough for you combo, and still be very streetable, thats what I have on my and I would not change it
