RENN-Spec | Photos/Video of Akrapovic GT4 System!!
We got in one of the first GT4 systems in the states and we quickly went to work to get this system on Constantin's car. We went ahead and wrapped the rear sections around the diff/axle shafts with heat wrap to keep the temps down in that area.
This exhaust is for "race use only", it does not have o2 bungs for the post cat o2 sensors, nor does it have any cats/resonators. As usual the quality of the Akrapovic system is amazing, even though the GT4 system is hand made the fitment is still perfect! Constantin's car is equipped with an ESS supercharger system, you can hear the supercharger whine faintly in the background. The exhaust note sounds much better in person, the video doesn't capure the sound too well with all the wind noise. Last edited by Tonester; 10-10-2010 at 02:14 AM.. |

Absolutely Sick setup! Straight pipes and super light is the best of both.
I'm curious to see how much power this setup would make over the Akra with HFC. The key is the weight savings though! Well played!

I have these mids and they made quite a bit of power over my catted challenge
But this with the Eisenmann is extremely loud, not so much in the cabin though as I expected which is very good |

Yes, we carry this exhaust system.

This system actually retails for $1,000 over the regular Evo system. |
