Outer Limits 4x4 Board

Has any one fitted aftermarket exhaust and had a custom tune.

If so how much power and torque did you gain and what does it drive like.

Can't answer any spec's, I bought a second hand 2010 Colarado with 3 inch exhaust vrs mates 2010 Colarado standard exhaust but has been chipped. With mine the turbo spools up much earlier, having driven both it seems to have to have more grunt, siginificantly more. Alas no dyno spec's only gut feelings.

Thanks mate, I am looking at a Beudesert 2.75" system.
