what are the best exhaust out there to run with a 2.7 and e85

 

Sound or power?
Catback or full system?

 

well mostly power but sounds good to and full system

 

ZZP or badmab header, Catelss 3 inch dp and a 3 inch zzp 3 chamber cat back.

 

the 3 chambered resonator?

 

I THINK the three chamber is the new muffler design but I'm not sure. If you wanted to go with their 2.5" cat back (I have a 2.5) I could get you a mid length header and catless dp for cheap, I know a guy who is selling

 

i have a brand new badmab header so whats the best to run with that?

 

Depends if you are gonna run corsa or zzp catback you can get away with going catless. Anything else and I'd get a catted dp. Get 3inch

 

are either of the corsa or zzp good and stay with a 3in exhaust right?

 

3 inch or 2.5 is all opinion. I'm running a TVS an have the corsa which is a 2.5 so that's up to you. I just named those two catback a because they are they only ones that sound good catless. I know the Gmpp is also a good sounding catback but not sure if its still good catless

Can't forget about Hahn. I ran a Hahn for about 6 months and loved the sound...but just sold it.

 

Stock cat back with over axle pipe and muffler. Cheap 2.5 inch. I run that with zzp 3 inch catted downpipe and bad mab header, sounds great.

It's usually said 3 inch is pointless unless you're pushing over 300whp
