So I put MBRP cat-back exhaust on my denali, and it blowing at WOT. Can't take it. Would long tubes with no cats help? It's sounds like a waste gate opening at WOT! And thinking about changing the muffler. Any help plz.

 

Sure you don't have an exhaust leak? Can you get a video if it??

 

Not sure what you mean by blowing??

 

No exhaust leak! Tight as ever!

 

It's only at WOT

 

It goes from a nice deep tone to a blowing sound. Like if u take a air compressor and open it up and bleed off the air at WOT. Is what it sounds like.

 

Have you tried contacting them about your concern??? Maybe there is something wrong with the product. Do you have any other mods???

 

Maybe you could tell us more about your setup, and a vid wouldn't hurt.

 

Could the muffler possibly need reversed ?

 

its a stock truck besides the CIA and now mbrp exhaust. ill try and get the vid made soon. but think ill just try the longtubes and no cats. or changing the muffler.
