I have a 96 Chevy 1500 5.7 350
I'm worried about back pressure mostly, just wondering if i could get some advice if this set up would be ok

Well the exhaust pipes going to the muffler are about 2 in and there is a single 2.5 in coming out factory
What i want to do is cut out the muffler and put in a Y collector from the Two 2 in pipes to the single 2.5 in out

Would i have any issues doing this?

thank you
Brian

 

Seems like that would work pretty well to me. Might sound better with some kinda muffler on it though. Guess it's all a matter of personal preference in the long run.

 

should work... i dont think you have to worry about backpressure on the 5.7s though... i dont know though i've never had one. but your setup should work fine if thats what you want

 

If you have any kind of cats that is plenty of back pressure
