Product Details

One of the most popular modifications in modern cars is the muffler delete. While not entirely an upgrade, it provides the owner with a much more aggressive exhaust note without shelling out large amounts of money in the process. Most full exhaust systems are designed to maximize horsepower while still sounding well mannered and devoid of drone. While this is fine for the discerning enthusiast looking to preserve the marked distinction of his or her Bavarian, some of us just want to hear our engine and are not concerned with the change in horsepower that may or may not result. Up until now, our options were pretty limited. Piece together a section of pipe and do some home welding, or pay your local muffler shop to toss a perfectly good muffler in the dumpster. 

Not anymore.

Fabspeed has come up with a solution that not only looks incredible but allows you to replace your factory muffler at any time you wish. Gone are the days of poor backyard welding and muffler shop mild steel. This is a muffler delete that you can be proud to show off. Designed and built in-house out of 14-16ga T304L 3"-2.5" stainless steel tubing you can be assured the fitment is on point and the durability will exceed the stock system. Another key point to mention is the weight saving factor. 14 lbs to be exact, is shaved from the rear of the vehicle by removing the bulky factory muffler.

Features:

  • Saves 14 lbs from the rear of the vehicle 
  • Constructed from 14-16ga T304L 3"-2.5" stainless steel tubing in-house at Fabspeed Motorsport
  • Includes Deluxe Quad Style Tips in your choice of finish. Choose between Brushed Single Wall Stainless Steel, Polished Chrome, and Satin Black tips
  • All Fabspeed performance products are backed by the Fabspeed Lifetime Limited Warranty

NOTE:  Installation requires cutting the factory exhaust near a factory break point. Everything required for installation is included. The Fabspeed system installs quickly over the factory piping using the included Torca clamp. Reinstallation of the factory rear muffler is quick and easy!
