Bryan: One month after install
- Living with the exhaust has been a pleasant experience. I had to first get over the feeling that someone was following me, as I wasn't used to the subtle tone of the exhaust coming from the rear at all RMPs. Next, I was worried about the much larger exhaust melting the rear bumper fascia. I've seen some exhaust applications that have eaten holes in the fascia, but that hasn't been a real problem. There has been a little scorching on the inside lips of both sides of the fascia, but nothing to be concerned about. One very unexpected benefit is that my gas mileage has increased by 1-2 miles per gallon. Bottom line: would I do it again? Yes. What would I change? the safety bracket
Chris: 1 month after install
- Chris Bull checked the rear apron around his Supersprint exhaust installation with straight tips and reports that no melting or scarring has taken place. He is VERY pleased with the upgrade and highly recommends the Supersprint exhaust to other 2.8 Z3 owners.
Spence: 1 month after install
- Chuck Spensor checked the rear apron around his Supersprint exhaust installation with DTM style tips and reports that there is some melting on the drivers side. However the scarred area is not very noticeable and the exhaust tip hides most of the damage. He is VERY pleased with the upgrade and highly recommends the Supersprint exhaust to other 2.8 Z3 owners.
- Update from Supersprint:
- There are two different 2.8 Z3 exhausts, one for the '99 on Z3 2.8 coupe and roadster, and one for the '98 and before Z3 2.8 roadster. The part number for the 99 is 78.67.06 or 78.67.66 (I guess one is straight tips and the other is dtm--don't know which is which). Supersprint experimented with a '99 Z3 2.8 coupe and moved the center bracket approximately 6-8 mm towards the driver's side of the car to give it a perfect fit. They did many runs to get the exhaust up to temperature and verified that it did not come into contact with the apron even under hard cornering. One point to note is that the '99 models apparently have a bigger cutout in the rear apron than the ones before that. For the '98 and before 2.8 roadster, Supersprint is modifying all current and future stock to have a side-to-side adjustable hanger to allow for precise fitting.
