high power-low db prototype muffler
 

ODM project sneak peak

Happy driving,
Team Ace

Could you please tell me/us what style of muffler is this? That is, is it baffled, straight through? Is there packing material involved that is going to age and result in a louder muffler?
What are the chances of a single exit muffler with the same design criteria of high flow low noise?

Initial impressions is that the exits hang too low, it doesn't look quite right. Might depend on larger tips but those look smaller than OEM.

This is a little OT question, but I have always wondered, why when the packing material has "aged" there will be an increase in volume?

It doesn't age per se - it gets moved around and compacted as a result of the exhaust flow and thus doesn't absorb sound as readily as time goes on.

Hey Snooze, muffler has a unique baffle design. Since it is not ours that's all I can say.

There is no packing material.

It's up to the designer if they want to do a single exit version. But everything is possible

If the general public thinks it's too low it's a simple thing to modify. Again, up to the designers.

The tips are from a factory FR-S which are small to begin with.

Has it been tested with ace header and front pipe? ;) Any sound clips or videos? I can't wait to ditch the rattling stock axleback!

Im in for single exit weight saving version

Car has Type B350 with OEM FP and MP

Not the best video...constructive criticism is greatly appreciated

WOW! Thats quiet!

I think for someone looking for a near stock sound it will be perfect. However while I'm okay with the DB level, I wish the exhaust note was sharper.

Sounds good to me, I'd want that if it was a full catback plus bigger tips.

Yeah, I think bigger tips are a must. Say 4", angle cut to match the angle of the number cutout.

Excited!!

Any plans for full catback?

4.5 / 4 inch tips? Ti option? Ballpark Eta? (i know thats a little obnoxious to ask so early in the r&d, but if you think you'll have the first ones out within a year I would definitely wait).

Just installed Ace header and in the market for a catback now.

Love your products !

At what point would this be needed over stock OEM catback? Can you test gains, if any, from using this rather than a stock catback?
