2003 Silverado 5.3 LM7 No Cats Thrush Welded Muffler Semi-Cold Start

[@KsKaylor]

Nice sound, got a similar setup on a 2004 model, never gets old.

I love it. It’s loud but not totally obnoxious unless I’m stepping on it.

Did it set off your check engine light?

[@jacksonreid6412]

@@timjohnson6457 Yes, check engine light is intermittent due to no catalytic converters

Cool truck and sounds good!

[@jacksonreid6412]

Thanks!

Can’t beat the welded thrush for the price!

How is the drone inside the cab

[@jacksonreid6412]

It’s pretty loud. Not too bad on the highway but around town it gets annoying.
