All good point points.RossaFerrari said:Warranty was enough to swing me towards Dinan.
From what I've read, sound like the GruppeM yields more performance gains, but I don't care a whole lot. If I wanted a lot of performance out of my car I should have bought an M3. My 911 gives me the raw speed and racecar feel I need every so often.
Wouldn't that be great! I just had an AA exhaust put on. They are a 2 hour drive from my house but it sure was nice going to a place where you can look at, touch, hear the product and talk to someone before you buy.Clem said:The best yet most difficult thing to do is drive 2 similar cars each with the products you are interested in. i.e. a 325 with a Dinan intake and another 325 with a GruppeM intake.
