A few weeks ago i had the stock muffler and resonator taken off my 05 Envoy and a Flowmaster 40 Muffler put in with a straight through exhaust with chrome tip at the back. Also had a 2nd pipe put in to make it look like dual exhaust but of course it isnt :laugh:. So now after weeks of driving the flowmaster is a little to loud for me and does sound a bit ricey. Even some of my friends say it sounds like a Honda lol. But aside from the drone and loudness i have noticed quite a bit of low end torque increase. How do i go about modifying this exhaust so that i quiet the drone and loudness( i still do want it to rumble, just not all the drone in the cabin) but still retain some of the power i gained from going this way in the first place? i also would actually like to make it a true dual exhaust. Thought? Comments? Suggestions?
