downpipedaddyUSA muffler

downpipedaddy.com had one goal for the downpipedaddyUSA muffler - to make the absolute best muffler possible, no matter the price, and then sell it for under $500.  

Our muffler is a universal fit, hand TIG welded, 304 stainless steel design, designed to flow well, sound fantastic, minimize rasp and eliminate drone. The construction, fit, and finish rivals catback exhaust systems over $2000 - and we could only sell ours at this price by creating a universal fit solution.

Our high quality welds, .065 wall stainless, and thick, solid baffles leave you with a muffler that feels incredibly solid, and weighs in at only 7 pounds. The Stainless Steel construction proves to be a strong yet lightweight source of metal, resisting corrosion and putting up with extensive heat cycles without fatigue.

Please note that the stainless construction will lead to the exhaust eventually growing to be colorful. Based on exhaust temperatures, you could see shades of yellow, blue, and purple at certain points on the exhaust. This can be removed with a metal polish.

On top of all of this - if you post a sound clip of your car with our muffler on social media, leave it up for two weeks - we will send you $100 back. Send us an email (admin@downpipedaddy.com) with your URL - and then a second one in two weeks, with your paypal or venmo address. We would love for you to keep your video up after this, but it isn't necessary.
