I am looking for a recommendation for a full exhaust system for a 01 s4. I am looking for a nice sounding full exhaust system. Possibly also where to get it in ontario canada. Thanks

For the cat back section I really love the AWE Twin 2, looks amazing, much lighter than stock, great sound without being overly loud.
For down pipes both the AWE and Milltek DPs with high flow cats both add significant hp increase, and more desireable sound. We have everything in stock, shoot us an email and we'll talk
