can somebody please tell me what the exhaust/muffler inlet/outlet measurements are for a 2000 Blazer LS 2 Door 4.3??? i cant find it anywhere, and i would really like to put a new muffler on my truck. thanks in advance.

 

I believe it should be 2 1/4" in and out. Check in the "Headers & Exhaust" topic. I think there was a thread in there stating the exact sizes.

 

WIN 2.25 is correct

 

thank you
