Test results

[Mikes07]

Isn't there a test results thread from blackbear somewhere on here for the 6.2 trucks doing muffler swaps vs cat backs? I swear I read it somewhere?

Only intakes. Exhausts provide little too no performance value.

Sent from a jelly bean.

Just do a muffler swap...way cheaper and as Jenna stated, no need to spend much on something with little gains

 

[Sho'Tyme]

I agree

Not 100% sure, but I believe most of the aftermarket cat-backs also drop your tubing size to a 3"...stock its 3.5"
