You will not be disappointed. I got the full exhaust and tune done by them and it is simply awesome. There is a marked improvement in throttle response and the fuel economy...well.. I'm sitting around 13.8L per 100Km at around 43Km/hr average speed. That used be around 16L!!! I tried to do a sound file but the bloody wind kept on interfering and distorting the sound!!! There are photos of my car and what the OTR etc look like.. Click the link in my signature!
David is the workshop manager and Mario does the tuning! All of them were really helpful and I was sitting on the couch watching my car being tuned on TV with the computer graphs etc. I'm sure they will help you out with all your questions.
ok...my sig doesn't seem to be working so here is the link
