Loud growl passenger side when pressing gas
I've got a 2003 Tahoe that just hit 200k miles and is now making an intermittent loud growl on the right side. Happens after truck is nice and warm, 5-6 miles of warmup, and the growl is sporadic, not constant (video attached with the noise clearly audible). Took it to a local small shop who I've always trusted, but I'm not sure they got it right this time. They said initially they couldn't duplicate then called back and said I need to replace the exhaust system from the catalytic converter back (not including the converter, but everything from there back). $1750!! He's ordered the parts but I figured I'd check here and see if I can get a warm fuzzy on this. Thanks in advance!

i dont see what a cat-back system would do to cause a growl. i know cats can rumble or knock. almost sounds like they want to guess at what it could be, but 1750 for a cat back is up there, should be able to buy one yourself for under 400

I thought the same thing regarding the "take a guess". But the manager said "this is common in these trucks, we just had one in here a few weeks ago, same issue". Unfortunately I don't have much time to mess with this, so I'm going to bite the bullet and report back here on Sunday and let ya'll know if it fixed it or not. I got $100 on NO.

theres a woman on here that had a shop tell her its common for the master cylinder to go bad and suck brake fluid into the intake and they just did 3 other chevys for the same problem. "google" the issue and see how common it is. i would try to rev the engine in park and see if it does it. also trry to things different like change gears or put it in 4wd

to go with what sub said, my 04 imp had the same issue. but when it busted loose it took some of the resonator with it. apparently the gap was small enough to let dirt and crap sit on top of the resonator and let it rust out.

Although I'm sure I could have paid less for the fix, they kept my trust another day. I was very skeptical after everything I've read, research I've done and people I've talked to about what the truck was doing. But I picked it up from the shop and it's fixed, and about $400 less than they quoted me. Would have never thought that noise was from the exhaust.
