The Helix cat-back exhaust is manufactured of the highest quality t-304 stainless steel and is warranted against product failure for 5 years. It is manufactured in three sections for economical shipping and ease of installation. All seams are TIG welded and will not corrode. This exhaust, along with the Helix intake, gives a dyno proven 8 horsepower increase. The tone is throaty without being obnoxious. The system comes complete with all hardware needed to install, including the highest quality band-style clamps. Unlike typical saddle clamps, these are manufactured of stainless steel and don't deform the tubing, allowing for easy removal and reinstallation for service on your Cooper.
