Each Billy Boat performance exhaust system incorporates 3-generations of fabrication skill and racing talent. Every system starts with T-304 stainless steel, known throughout the industry as the highest quality material practical for "after-cat" exhaust applications. All exhaust tubing is mandrel bent on sophisticated CNC machinery for a precise fit and uninterrupted exhaust flow. What's more, the use of T-304 stainless steel flanges offers high strength and complete resistance to harsh elements. All hangers, resonators, and tips are T-304 stainless steel as well. Billy Boat Performance Exhaust mufflers are crafted in-house with years of racing and street development invested into the design. Each muffler is tuned to match its application for the best possible performance gain and sound quality combination. For strength, the muffler end-plates are radiused at the inlet and outlet preventing premature cracking. Additionally, reinforcing gussets are used when necessary.
This product was easy to install, and the quality of the surface finish and sound is absolutely bar none. This was all to be expected for an exhaust system of this caliber and price. There are no horsepower gains to be had with this system, and fuel economy did suffer an mpg or two. I certainly expected this, as the original bmw exhaust system flows really, really well. One thing though, the new system is much lighter than the old. I didn't weigh either of the systems, but it was obvious when handling both units that the BB system was lighter. Now the bad stuff, the fitment wasn't perfect. I don't really understand why Billy boat doesn't use the EXACT same mounting tabs in the EXACT same location. The cat to muffler pipes were pretty close or exact, but the muffler was way off. I would have coupled the two cat to muffler pipes together to be more like the OEM exhaust. I was only able to get one of the two muffler clamps on, which isn't great but the new unit is so much lighter than the old one that it doesn't really matter. That does cause the muffler to be slightly cockeyed, but I don't really care. I love the sound, and I get a lot of compliments on it. Really super nice growl at idle, not too loud. Once you let the throttle go sounds... just... amazing! Music to my ears!
