GTM Stelvio Full Exhaust System

Pics and video below of my all-new GTM full Stelvio exhaust system, which I can hand-build to order for select buyers. Any of the individual pipes/muffler will fit the stock items, meaning headers only, Y-pipe only or muffler only. This is a stepped header design that has proven power gains. I will try to get it on the dyno in the near future. Contact me direct email for info, or I now have them online for purchase here; https://www.guzzitech.com/store/category/exhaust/stelvio/ -- I will ONLY build them to paid order. ~7-10 days to ship.

Sweet! I wish you would have had that a year ago when I bought my MIstral. Your system sounds very sweet Todd! I assume you need the PCIII/AT package to run it properly? My buddy has a new Stelvio but with snow, we haven't been able to get together, but when he hears my exhaust, he's going to want an aftermarket can I am sure, and I'm going to show him this one!

Thanks Scott. It’s even better in person of course. My flash for the muffler only will be good. For the full system I would recommend the full kit... as I also move the 02-sensors forward to just off the heads where they are far more accurate.
