The Vibrant Performance STREETPOWER Round Muffler delivers unrestricted exhaust flow and aggressive sound in a durable stainless steel package. Engineered with a true straight-through perforated core design, this performance muffler eliminates restrictive baffles to maximize horsepower and throttle response.

Key Features:

  • True straight-through perforated core design for unrestricted exhaust flow and maximum horsepower gains
  • Densely packed with premium multi-layered sound absorption materials for a deep, aggressive exhaust tone
  • 4-inch inlet and 4-inch outlet in center-center configuration for versatile installation options
  • Constructed from T304 stainless steel for superior corrosion resistance and longevity
  • TIG welded inlet necks and outlet tips ensure maximum weld strength and durability
  • Round canister design for compact fitment in tight spaces

Ideal for street performance applications where you need both power gains and refined sound control. The STREETPOWER series strikes the perfect balance between aggressive tone and livable daily driving volume, making it an excellent choice for street-driven performance vehicles across automotive and powersports applications.

Had what I need when I needed it. Thanks

All good

Great seller. I ordered a banks intake system for my 2001 silverado and I recieved exactly what I ordered. I'm very happy with this seller as a matter of fact I would be ordering my exhaust system from them. Besides they had the best price

First time using Autoplicity. Online ordering was fast and easy. Price on tuner was lowest I found. I called customer service with question about shipping,Got right through.Shipping was FAST. I just found me a new favorite online store. Got to give Autoplicity an A+.....

Smooth and efficient

Great customer service!Fast shipping! Product exactly what I needed!

Just purchased a B&W 5th wheel companion hitch to tow my new camper. Got an awesome price on it and shipping was quick. I would make a purchase again from them and would recommend Autoplicity to a friend. AAAAA++++++++++++ <br><br>Thanks<br><br>Dennis

Great price

best prices on internet quick ship from seller great buy

Wow I love the race ramps I bought for my 2009 dodge challenger srt8 I used Thelm to change the oil 2 days after I got Thelm and they worked great I have extra clearance I wouldnt think of any other place for my parts gas shipping great prices and great shipping prices I'm a very happy customer

The best deal on the same parts that everyone else has. Saved me $75 from the best price any 'Seller" had on the "bay". Will be back. A+ service.

Nice and quick

Very good first experience with Autoplicity. Order arrived promptly. No issues.

It took a day or two for them to ship my order, but it arrived quickly once shipped. The price was by far the best available.
