I had the quad tip exhaust from Inside Performance fitted a few weeks ago and it has to be one of the best mods I could have had done. The new exhaust both looks and sounds absolutely Fantastic. What I found interesting is if you keep the revs low and light on the gas then I swear its quieter than the original but step on the pedal and its a completely different story.
I'm told that it also brings me about 10 PS more.
I havent made any sound clips yet but have a couple of pics. showing the new exhaust.
The service from Inside Performance was first class. I dropped my car off at their garage in Mainz and a couple of hours later the conversion was complete.
Many thanks to the guys at Inside Performance
