Best would be the magnaflow catback system, but the axleback would be better than just the muffler. All depends on what you want. If you want performance and sound go full catback. If you want sound for cheap, go axleback or just muffler.

 

Well I mean when I changed out my muffler on my truck total cost was 140.00 dollars for the muffler and installed.

 

what muffler did u get, and did u have the shop weld it? I know all of RRM's products are just bolt on stuff u can do at home.

 

I got the flowmaster 40 series. Yea it was all welded up and even welded and braced up all for 140.00 flat. That included all labor and muffler.

 

thats not bad what were the gains?

 

I had three power mods at the time and each one gave me roughly 10 horses. There was a stock truck that dynoed 30 horses below mine. So out of three they averaged 10 horses each. Had a CAI,Exhuast,Superchip.
