Hi all, first time Audi owner but have had an wide range of cars previously - ive never gone down the tunning road. like most ive spent fair bit of time researching options and MRC seem to highly recommended. i put a call into them today and had a good chat about a stage 2 upgrade package which involved software, pulley and air intake. they didnt seem to think an exhaust change would make any difference to performance (apart from sound) im keen to use MRC based on all of the reviews etc. is there anything else i need to be aware of etc. Thanks
