Turbo 5.3 w/ Corsa exhaust
I have a 2008 Silverado 5.3 and I just put on a single 76mm. The truck has a Corsa DB exhaust that sounded absolutely wonderful on an otherwise stock 5.3
Now after the turbo install it sounds like a straight pipe or a glass pack. I doubt this is normal from losing the cats and adding a turbo.
I used a sawzall to cut the exhaust and connect to the downpipe. Possibly shook something loose in the muffler??
It is so bad I don't even want to drive my newly boosted truck!! Any ideas?

No it's actually better when in boost. It's in the low to midrange rpm before boost comes in. Around 2500-3500 rpm. It may be normal but sounds really obnoxious compared to how it was before. It's no longer smooth and throaty--more like a wrapping sound that you get with a glasspack muffler.

Brought back an old memory lol. When I had the 07 in sig with rear mount installed in place of the muffler and no tail pipe, it sounded stock. But when it was full boost it sounded like a high pressure air hose. SSSSHHHH! Was some funny ****...ok sorry back on track...
