Review on 🔧 Gibson 615532 Single Exhaust System - Stainless Steel by John Collins

This is a good system, well made, but had to be modified a bit for installation and is too loud for my taste in the car, and after 3 hours the highway smells still after something burned. The stock system had a heat shield when it went over the axle, this system doesn't. I'll try boxing the muffler to see if that helps with the interior noise, if not I'll return the stock system. Not sure about the power increase or fuel economy, doesn't look better, could be worse, I will do further analysis and report back.
