6.0 cat delete questions
I've recently did the cat delete on my 4" mbpr exhaust, to lower my egt"s. Now i have have a 40 & 60 mph low frequency rumble, that's sounds sweet. The problem is my wifie dosn't like it (imagine that)! Can i wrap the exhaust with a
high temp fiber tape, but not the muffler. Would their be any consequences for
doing this? Higher exhaust temp in the muffler or turbo? Thanks, in advance

I have the same system and have not noticed the rumble increasing at those speeds. I have not yet heard a complaint from the wife or kids. I just notice it is getting a bit loud when towing the passes with a 10000lb trailer. I did install dynamat when I installed the entertainment system and maybe that is the difference. My wife does have a aftermarket performance exhaust on her superchargered hummer though which is just as loud.
