I was wondering your guys's opinion on an exhaust. I already have 2.5" true dual straight pipes on my 6.2. I was wondering if it would make any difference if i was to Y-pipe it into a single 3". What do you guys think? I'm open for any suggestions, so feel free. Thank You Guys!

Hey your blazer sounds like its got mufflers on it still!!!!!!!!!!

I went to a single 3 with a large truck muffler.


I didn't notice any difference over stock. they say there are gains, but they are small. In conjunction with turning up the pump and an open element filter it may work much better.

White Duramax...atleast i dont have 3 quarts of fuel in my oil...some times the oldies are the best! Straight piped or not... We'll see how she sounds and smokes after this weekend!
