    Opinions On Third Cat

    I have a 2013 Yukon Denali that I just had a Corsa sport catback put on. It sounds really good and I'll be posting clips/review soon. Although the exhaust sounds good I'd really like a little more volume and I was wondering if I replaced the third cat with a high flow cat would it give me more...

    2013 Yukon Denali issue..normal?

    Update: Just got a call from the service center they assured me it was normal and if anything were really wrong one of the computers would tell me. Still if any of you have experienced something like this I'd love some input.

    2013 Yukon Denali issue..normal?

    When I'm cruising if I blip/rev the engine or hit the throttle 50-75% when I let off the throttle the rpms will stay at 2000-2500 and it sounds almost like the transmission is stuck in a gear too high or too low I'm not sure. It doesn't do it everytime but after it happened a couple more times I...

    Cold Air Intake Yukon 6.2

    Your customer service is excellent and for that I thank you. I've been emailing back and forth with BB and everyday I get closer to pulling the tune trigger, I'm just paranoid about my warranty.

I'd like to put the cats and catback on at the same time however my concerns are warranty and codes, I know you can tune them out but I know for sure it can void a big part...

    Cold Air Intake Yukon 6.2

    For any of you that have added them to your 07-14 Yukon Denali do they seem to make a difference? Do they create an improved/louder exhaust note? I've seen they bump the HP a bit, not much without a tune but would you recommend doing it? A Corsa Sport cat back is going on also.

    2013 Yukon Denali Corsa xtreme

    Thanks for your input. I'm gonna go for it, it says it won't ship until 2/10 but I'll post up a review/sound clips when it's on. I emailed Corsa about the sound level they said if I want more sound from it high flow cats would turn up the sound considerably however I don't know if that would...

    2013 Yukon Denali Corsa xtreme

    Hello everyone, first post here goes. I own a 2013 Yukon Denali with the 6.2L engine. I've been researching exhausts watching youtube clips with good quality headphones and reading reviews. I've been interested in the Corsa sport (PN 14880) however a theme that seems to come up is its too...
