Hushpower (Flowmaster) DBX Mufflers

I was on my second rattley stock muffler and was looking for something with a little more aggressive sound. These look like straight through mufflers but actually are not. They do employ some noise canceling technology. They are currently available only direct from Flowmaster by special order. Just finished installing a pair yesterday and I am very happy with the result. Barely noticeable at idle but a deep growl when accelerating and a pleasant bass burble when letting off the throttle. Noise level at cruising speed is louder than stock but no annoying drone.

a sound clip at idle and drive by would be nice if you can get one.

I paid $250 for the mufflers plus shipping, about $75 for tips, clamps, bends and bar stock, and $30 to have it welded. I did all the measuring, cutting, bending, fitting and tack welding myself.

I'll see if I can get a sound clip.

I'd like to hear that and the "hushpower" as well!

Hushpowers

Glad to hear you like our mufflers. I work for Flowmaster/Hushpower. These are very unique mufflers with patented design and cool exterior temps. We recently put a set on a GTP Spice race car to meet sounds requirements for Infineon Raceway. With no loss of power. Check them out online at www.hushpower.com. Glad you like them. Love the creativity.

Flowmann, your company should make these for boxsters. All the aftermarket ones we've used on this forum, including me, are "prone to drone" and the cabin resonance is deafening if you're caught in the rain in the city and you have to have the top up and you're forced to drive in the 2-3k rpm range.

I'd be happy to work with you on a prototype

How does the weight compare to the OEM muffler?

Ok, I recorded some clips with my Ipod and posted on Youtube. The first is idling and reving a bit. The second is a drive around the block. The third is a driveby. Meanwhile Flowmaster has asked me for a couple photos and a blurb for their website. Maybe I can get a free t-shirt or something.

Well, I know vids/sound clips don't give us a 100% idea, but it's better than leaving it to my imagination. I have to say from what I heard of your little cruise around the block, those sound pretty nice. Like you said, a little loud when they need to be, but not ridiculous.

Now take a passenger with you so we can hear a little highway cruising.

Reviving an old thread. To the OP, do you have any pics of the setup?
