APS 3" true dual. No crossover. Exhaust pulses can be felt 10 feet back at idle. Probably the most obnoxiously loud and annoying exhaust system I've ever dealt with. Wonder if the velocity and turbulence around the exits is contributing to the wrap-around. Permanent soot stains go up the bumper diagonally toward the sides (thank the previous owner for NEVER washing it LOL), a couple feet more and its at the windows.

 

A good Polishing compound will take that off, no problem……

 

That's why I was asking. I was thinking, maybe a single would push the pulses out further from the car?

I guess my car will be a good comparison with it's single 4".

Or a really bad one seeing as it's a vert lmao

 

I'm thinking your side exit is probably better since the wind will pull the exhaust backwards off the side... with the rear exits it gets looped back around in the vortex behind the car. Maybe a big ricer wing would help.

 

HFC'S are the only fix.

 

The wastegates are currently dual side exit, but the exhaust is single 4" aluminum out the back with a little tiny vibrant muffler lol.

About to go home and put together the lower intake now that I finally have the plugs to fill in the extra taps we put in for the direct port meth
