Been looking at replacement of the factory exhaust on my 2007 RS4. I really like the sound of the GMG WC exhaust out of California. Milltek is my second. Anyone heard of western canada shops that will install? Looks like i'll need to order and ship the system to my location from the US. I'd switch it myself as it is a direct bolt on system but i dont have a hoist and I'm not too fond of trying to do this in my garage! anyone having opinions or input/experiance is appreciated.

 

Had the Milltek on an RS4 and never had more than a few days go by without a compliment on the amazing sound. I truly miss it ! BTW, it was resonated non-valved ...

 

Good to hear. Miltek is a close second, however to my ears I favor the lower tone of the GMG. Its a personal preference thing I suppose. Realistically i dont expect any significant HP increase but figure that the weight difference and better tone is worth doing it. Might take a road trip this summer to California and have them installed. did you notice any performance difference with the Miltek added??

 

Purchased the car with the Milltek already installed so can't provide a comparison.
