This system utilizes the stock header assembly. Bolt on and slip-ons replace the stock restricted muffler resulting in better sound and an increase in power.

Retro Drag Slip-On(s) in Black.
M4 Performance Exhaust engineered the Retro Drag dual slip on exhaust system to offer an original exhaust that provides performance increase along with the obvious sick looks with the black ceramic coating.
The look of the M4 Retro Drag dual exhaust is not the only thing separating it from the others, the sound produced from this exhaust announces pure power.
Replacing your stock mufflers with the Retro Drag cans will lighten your load thanks to M4's diet plan of cutting out unnecessary materials.
Stage 2 quiet insert Q3 is optional (sold separately).

Note: All M4 systems are designed and intended for closed-course competition use only.

Sounds of speed

I've never had the pleasure of owning the M4 exhaust and now that I do, i couldn't be more happy. I read truly surprised by the sound and appearance of it. Since I'm not a mechanic savvy person, i can't give any performance data however im super impressed.
