What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[George B]

not that I know of, I think corsa sells or used to sell a cat back which was not cheap 1200-1400 usually
the escalades had a dual pipe option but you have have the rear bumper cover and either remove the spare or modify the pipe, not sure what the difference is in that regard

I asked because I wonder about mine. Seems louder than others but I believe it is a factory system.

Replaced the hood pins for my under hood lights on both trucks, they tend to get rusty after 2-3 years, cheap and easy to replace

Can't they collapse internally? If so that might be why.

The baffles could've collapsed internally making it louder.

Took the rig to OBX to hit the 4x4 beach with the family for the week! Sun, Surf, booze, and a lot of fishing!

I’ve had a factory muffler or resonator (forget which one) fail before internally. All the glass insulation?, literally strings of glass started blowing out of my exhaust tip. It started to look like my truck ate a wig and was śhitting it out.

My factory muffler was sounding pretty "farty" chocked up and muffled before I swapped it out.

when I went to have the oil changed I didn't have the container with me so the lunchbox crew put it in a empty Gatorade container and rinsed it out with water DOH!

I could not imagine a response to my sample if I had the wee ballas to send it.

 

[Doubeleive]

I just did this one to make sure there is nothing going on that I don't know about
