Right now I have no cat ant muffler on backwards, but it doesn't quite sound the way I want it to, to much resonance in the cab. I want it to sound aggressive on take off but i'd like it mild when going down the road, as I drive 60-70 miles to see my girlfriend every other weekend, and it just gets annoying. I'd like to do a cheap high flow cat and muffler upgrade, what do you guys suggest? I'd like a deeper tone, and somebody suggested Flowmaster 40 series with 2 3/4" pipe. any other suggestions?

This is what I want.

 

I have put a cherry bomb straight flow glass pack... but i want to change the tip for one without that resonator in it....

I run a 2.5 inch flowmaster super 44 with a magnaflow high flow cat. The tone is very deep and aggressive, the aem bruteforce cai helped the tone as well. I don't mind it going down the highway. I had to do the spark plug non fouler trick to get rid of the cel because of the high flow. When my tuned pcm comes in I had him remove the downstream o2 sensor so it wasn't worth the time but ohh well lol

 

i was thinkin of switching up to a flowmaster super 44.... it has my attention because people are saying too little backpressure caused by straight flow mufflers are no good and you ned the backpressure....

 

I'm not sure of how much back pressure you really need. I know several guys that just run straight pipes. Although, after they heard my supper 44 they soon put one on lol. Its a nice deep and agressive tone that isn't annoying like straight pipes lol.

 

Gonna change up soon... deffinately
