Arguably THE BEST modification for your 135. No cutting necessary, Direct bolt-on for a complete transformation! The combination of 135 and muffler delete surpasses all sound expectations and is suspiciously easy to install! An impressive direct-fit solution, with no cutting involved. With the new muffler delete you can transform the sound and driving experience of your 135. A simple installation that can be completed with hand tools allows you to take your car to the next level at home in your garage! At the rear of the car just below the back seats, there is a factory flange with two bolts, simply remove the two bolts and barb from the factory hanger and swap with the ECS Tuning muffler delete for a direct replacement. Its as simple as that! Check out the installation instructions for a list of tools you will need! -- CLICK HERE FOR INSTALLATION INSTRUCTIONS -- The ECS muffler delete removes the heavy and restrictive factory exhaust muffler and replaces it with a high-flow, straight-through exhaust pipe. This adds a louder exhaust note in a simple, cost-effective way without replacing the entire exhaust system and is fully compatible with the OEM rear valance. The muffler delete creates a noticeable increase in exhaust sound and more exhilarating turbo noise, without adding significant drone at cruising speeds. As an added bonus, this muffler delete shaves off 23.0 lbs., weighing in at only 7.0 lbs compared to the OEM muffler at 30 lbs! Features and benefits: Enhanced exhaust tone Simple installation (with instructions!) 23lb weight savings! (Factory muffler 30 lbs, muffler delete 7 lbs!) Swivel tip adjustment capability ​ Good looking and durable 304 stainless steel construction Factory position exhaust hangers Dual staggered tip exhaust tips Installation and Support: Installation is as easy as unbolting, placing into position, and reinstalling fasteners! Tools you might want for the job: Exhaust hanger removal pliers - T379176 Product Development: Our muffler delete was designed, engineered, tested, and quality inspected by our Research and Development team in our Wadsworth, Ohio facility.
