I got a buddy with 27 years experience to install mine. I got dual three inch with 3 inch ravin mufflers. They flow good and sound bad *** and bent installed for 400 bucks. Yep so I got a good deal and a good job. Not it wasn't cheaper pipes.

 

the true duals had the better sound id imagine?

 

You got it bent for 400 dollars? Was it mandrel bent that you cut up or just a regular bender? What material was used? What is the HP or Torque gain?

 

Like I freaking know I went in with open headers driving through the my city at 7 AM in the morning. But if you match the size with horspwer and back pressure you get the best efficiency.
