So i should be fine with CAT back straight pipes. No muffler, just CAT's?

 

I hope you dont live near anyone, or drive after sound ordinances....

 

Here is a sound clip of a Mustang from Cherrybomb. I know Youtube has a Hemi/cherrybomb clip.

How much do the cherry bomb extremes cost and is it best to get the dual out 2.5" or single 3" out then make it turn to duals? Thanks for that link, those extremes sound really good.

 

I have everything off. Where the muffler bolts to the Y pipe. And I have been running this set up for like 4 or 5 months. I have a Flowtech muffler to put on. But I just don't have the time and I don't know how to weld. Hope this helps. Also I got a gain of 1.5 MPG.

 

oefootball_70, do you have the cats on?

 

yeah, exhaust manifolds all the way to the Y pipe. All stock. After that there is nothing. No problems with back firing. And I haven't thrown any codes. And it is loud as hell.

 

Was there any performance hits, loss of power?

 

I feels more powerful. I think that old muffler/exhaust system is so restrictive it doesn't run as well as it does with nothing on.

 

Sounds good, I cant wait to get mine done.
