Always good to see local RS3s coming back for more! had one of our stainless valved exhausts installed a few months ago, and now he’s taken it further - pairing the exhaust with our downpipe.. for track days 🔥

TTRS V1…. .5😤 We’ve always optioned the V1 setups with smaller rear mufflers due to the space constraints in the rear of the vehicle, but that’s come to a change! Our 8Y exhausts use these same mufflers placed in the rear with great success, so we gave it a try with reworking the placement on 8S/8V. Needless to say it worked out great. Sound clips are coming. Product going live on the site soon🔥🔥

Porsche Turbo S exhaust 🔥 The goal was to achieve a nice change from open to closed valves modes. Priority flow through 3.5” tubing from turbo outlet flanges - with 2.5” closed valve routing through the mufflers. Finishing it off with handmade dual wall tips. TIG welded & backpurged of course 🤠

Single exit w/ muffler, straight center section no split, and 4” downpipe is rowdy 🔥🔥 RS tip on the single exit - just an idea we played around with, but it would be cool to block off the other side 🧐
