Well, Im going to run either a 2.5'' or 3'' into a flowmaster Y, and into a 4 inch mufflex right before were it goes over the axle. I have a 383, that has 525 HP at the flywheel. I have shorties now, but am going to put Hooker super comps on there. I have a hacked up Y-pipe, into a a un-known 2 1/2 cat back. So needless to say, anything would be a huge improvment. Also, I know there is a huge debat on backpressure, but should I do 2 1/2'' or 3''?

Any other ideas?

 

so your gonna run dual exhaust from the headers to just before the axle and have it Y in to a mufflex? muffler before the axle or just the Y is before the the axle?

why not just get the mufflex Y pipe and their 4" exhaust system

 

Seriously! If what you wrote is exacty what you mean, your wasting a lot of money on a system that is not going to do you any good. Your best bet would be to get the mufflex systen, along with the mufflex y-pipe and put everything in the stock location like it's supposed to be.

 

Well their Y pipe is only for hooker super comps., which I dont have.

 

your first post states that you are going to get hooker super comps. so what's the problem?

 

yeah, going, as in, probally next year.


But, if everyone is just going to criticize me, then, whatever.

 

get it fabbed to the headers at an exhaust shop using a flowmaster y.

 

They look more like opinions than criticizing.
