    Default 2011 Chevrolet 2500HD

    Looking for catback exhaust and cold air intake for my new HD 6.0. Very limited selection so far. Anyone have any suggestions as to where to look.

    Already called them. I could modify their cold air intake (theirs is for electric fan), and they offer no catback yet either. The HD's have a new frame so the older mstuff will not fit. Thanks for the reply.

    Exhaust wouldnt be a problem for any decent muffler shop, unless your looking for an exhaust system.

    Last Sunday I installed a K & N chrome tube intake but it was not easy. They do not make one for the manual fan so this one had to be modified. Cut out part of the fan shroud and then the fan hits it. Have it pushed up with some foam but will try something better later. Does sound good though. I paid $277.87 on ebay.

    Dealing with a warranty issue, being told I may have voided my powertrain warranty, and having only installed FOG lights, you need to able to reinstall the stock intake and exhaust systems. GM has specifically told dealers to void warranty on intake parts like MAP sensor if an aftermarket oil airfilter is used. Improperly oiled airfilters are causing GM issues. Also any tuning that changes the factory HP will void the warranty on the drivetrain. I am now resigned to waiting 5 years for my warranty to end. I don't need the stress.

    The volant cold air kit works perfect........the second o2 sensor needs to be tie strapped but worked perfect and is very high in quality. Check they are really good. Good luck fellas.

    Right now aftermarket parts are very limited. I'm still waiting on finding headers, full exhaust, and a good programers still.
