i bought my A4 about 2 years ago and it already had a aftermarket 3R Racing exhaust on it and went to the end of the internet trying to find out if they are good products if you have ever heard of 3R Racing tell me what you think of their products
thankyou

 

if you cant find it, they probably arent that great. Since its an exhaust, i wouldnt worry to much about it aslong as its not making stange noises or rusted through

 

if its a fart can rip it off!
