So after many hours of trying to figure out which intake is the best for a B6 S4, I noticed that I am stumped. The companies that I found that make an intake for the B6 are evoms, lltek, carbonio, and stratmosphere. I feel that the Carbonio is too expensive, and stratmosphere seems to have the best quality. Any suggestions?? Also, does anyone know anything about a Motorklasse exhaust and if it is actually worth the money?
Look-out for remus exhaust... If i was you... i will do a custom made job for the entire exhaust system.... no res, high flow cat, remus or magnaflow exhaust bolt-on to the original exhaust line = cheaper job and a good overall choice. its much more expensive to buy a complete exhaust line and the sound is approximatly the same....
If it helps you at all, I have the hyperflow intake from stratmosphere on my B6, along with the milltek non-resonated catback exhaust. The exhaust sounds awesome and you definitely feel a difference in power. The hyperflow intake improves throttle response and also helps the car sound mean. Installing this intake is easy, you can definitely do it yourself. Go with the hyperflow carbonio is too pricey and if you research the forum allot of guys seem to feel that lltek is not a great company to deal with.
