    Speak softly and carry a big stick—Flowmaster HP-2 Series Hushpower Mufflers are expertly engineered to unleash a subtle, warm rumble from a high-performance, straight-through muffler design. A rich tone and record-breaking power—it could only be Hushpower.

    Don't let their seemingly simple exterior trick you into thinking these Flowmaster Hushpower Mufflers are simple on the inside. The belly of your muffler boasts advanced exhaust flow technology that cancels out unwanted noise, leaving behind a rich tone reminiscent of '50s cruisers. Plus, Flowmaster mufflers are equipped with Cool Shell cases to further reduce drone and insulate against heat.

    Only premium stainless steel is used to craft your Flowmaster HP-2 Muffler, and you can choose between 409 (tough) and 304 (tougher) stainless—both can be polished to a brilliant gleam. Plus, the compact size of these Hushpower mufflers makes them the perfect fit on street rods, lowriders, sport trucks and customs. They're also backed by a Limited Lifetime Warranty.

    Nice workmanship. Sound and design (shape) may effect m.v. inspection. A 2" muffler tip may have to be welded or adapted. Small outlet; u-know. Hangers and connectors need to be welded and or installed. A nice starting point.

    These have a unique sporty sound and not prone to droning. They flow like crazy, and picked up noticeable power on a couple of the cars I use it one. The smaller 12 inch version makes an awesome resonator. Since they are fully stainless and not relying on fiberglass packing, they will last forever. best mufflers i have ever used.
