hey. i have a 3" magnaflow single in single out with a turn down. it sounds "okay" but i want something much deeper and/or louder. my gmc had a flowmaster 40 with a turndown and i LOVED the way it sounded. thanks everyone!

 

maybe switch it out for a flowmaster? or if you want really loud go with a cherry bomb but rember you need to have some back pressure

 

run larger pipe before and or after the muffler. i also like the sound of 3" pipe from as far as they can cut to a 4" turn down... it has a really good rumble and if you do your turn down right its not very loud in the cab.

 

I installed a manual cut-out and it made a huge diffrence. Louder, Meaner and just overall more aggresive. I paid $28 for the part and $30 to have it welded on. The best part is, put the cap back on and your back to your old setup. check it out.

 

and i have the same set up as finalday and i have to totaly agree with every word he says great mod. ive bought so far

 

dumped Flowmaster

 

Hey travis, where did you get your cut-out installed at. Between the cat and the muffler or infront of the cat?
