I've got a SI/DO catback Maggie system with dual side exit (passenger side only in front of rear tire). I want to add two more pipes to the other side of my truck but have been told it is illegal to run true duals here in VA.

Is there even an option for me? Will I lose torque if I change out the muffler to inlclude four pipes?

 

Can't even be done. There's a big black thing in the way and if it gets to hot, it tends to explode. What would that thing be called.................. the fuel tank!

 

x2. Fuel tank prevents you from doing that, and if you get it done anyways no one will inspect your truck. The only way to run that kind of setup is to run the left bank outside of the frame. If you want the look, fab up dummy tips.

 

sorry, won't work.
