Hey
What mufflers/exhaust are people running on noise restricted tracks.
New track opening just north of Calgary, Rocky Mountain Motorsports and we have a 95dba limit at 50ft.
My car is pretty much a dedicated track car. 2011 GT with stage 3 cams LT headers. Has resonators, don’t remember the brand. I had Varex valved mufflers. Too loud in open and on the Dyno lost 40hp with valves closed. Local mustang shop suggested Borla XS. Had those installed today and shop said it is almost as loud. I haven’t picked it up yet.
suggestions?
