In the video we show the comparison between stock exhaust, RENNtech Sport Mufflers, and RENNtech Sport Mufflers combined with the RENNtech Downpipes.

We tried to capture the sound differences in multiple scenarios; start-ups behind the car, revving behind the car, fly-by’s, and launches with an exterior mounted GoPro.

Both, our Sport Mufflers and Downpipes are bolt-on solutions. No cutting or welding is required. All of these RENNtech exhaust products are designed and manufactured at our Stuart, Florida headquarters.

I have already spoke to John B about bringing my car in. I do have a question, when it comes to taking my car in for scheduled service, how quickly could you return my ECU to stock & then back to the upgrade? I live close to Stuart but it is still a good couple hours drive. Also, would you need the car there each time?

Nice video!! Your R1 package lists 611 hp. When you add downpipes to the package how much HP can you expect total?

Does downpipes and mufflers void manufacturer warranty?

Thanks!

Hi! What kind of muffler options do you have for a non-performance exhaust car? And does the muffler and downpipe combo in loud mode cause any drone at highway speeds? Thanks!

Chris Estes

Yes ^^^ what he said!!

Also, any progress on OBD/hand held/non remove ecu tuning from you guys, I'm dying to tune and slap on some downpipe but don't want to have to remove the ecu every service...😣

Can you share this info? I'm curious as well as to how much more HP/TQ your downpipes add with the tune.

+1 for the non-performing exhaust people. Will I need an Ecu update to get rid of codes or is this exhaust even compatable with a non - performance exhaust?
