Sometimes things just don’t line up the way you want them to, and it becomes necessary to improvise. Use these adapters to change the diameter of an exhaust pipe to a larger diameter. They’re swaged to slip-fit the mating pipe exactly, needing only a simple muffler clamp to achieve a perfect seal and mechanical integrity. No welding required.

There are always those purists who push the envelope in their pursuit of maximum performance. It is for these true enthusiasts that we build what is one of the most extensive line-ups of muffler deletes in the industry. Extreme performance and extreme sound can be yours.

It’s only a matter of a few minutes to give your exhaust system the ultimate reduction in back pressure. Just unclamp the muffler and hang this polished stainless delete pipe in its place. It uses all the factory hangers, so it looks like it belongs there. Great for car shows, drag racing or dyno testing, but will probably get you a ticket on the street.
