straight exhaust.
 

I am reading 2 different things, Would a muffler delete 4 " pipe burn turbo or damage engine? Thanks,

No damage will come from straight pipe...

Thanks for your response, planning on ordering Diamond Eye 4" muffler delete tomorrow.

if you have a gooseneck hitch, the diamond will hit it.

cant go wrong with the staight pipe, when i did mine i noticed a reduction in egts, better fuel mileage and a little more power also maybe a few more psi of boost

Straight pipe works great and sounds great!

My 5" sounds great
