We were asked to make a super light, no compromises center muffler delete that would work in concert with our Race headers for a racing application. So no valves, no care of drone, just light weight and makes power. Most all center muffler deletes lose power in the mid range when coupled with Race or Catted headers. We wanted to solve that, so we made one our way... Using a reverse Megaphone design coupled with a 3.5" Xpipe, made from 625 Inconel for long life, light weight and wicked sound. When coupled with our Race Headers the car truly sounds like an RSR!

• Loud, will not pass sound at Laguna
• Will wake the neighbors
• Is livable on the highway, can talk on the phone above 2500rpm it gets quiet(ish)
• 5.5lbs so combo of Race headers and Crack Pipe is 60+ lbs weight loss.

We're still making fitments but the plan is to offer it for 991 and 997 Race headers, Street Headers and possibly OEM headers. Just to be clear, it is LOUD! and your valves won't work, etc... If you're on the fence at all, this isn't for you, get our Loud Muffler...


Will update with Dyno data, for now enjoy the crazy RSR Sounds, videos below

Our Engineer Mike is pretty excited about it!








5.5lbs








Connector pipes will be made in Inconel as well, but for the first article had to confirm fitment and made it from some 321 we had on hand.

Phil needs one.😁

Waiting for full Inconel system with wrapped headers.

you won't have to wait long.....

want loud, but not doing headers

Thumbs up. Sounds like the 454 I had with straight pipes at idle and like an RSR on full boil.

I can't image how loud that looks. haha

bogey1

That sounds ridiculous! I need to move out of the City of Atlanta so I won't need catted exhaust!

Gasman85

Want this for stock headers and cats

Since we're moving to old school F1-derived materials, can you make something out of berillium next? Even if it's door handles, that's ok.. I just always wanted something out of berillium

Good stuff for speaker drivers...

You don’t need emissions in Atlanta for the first 3 years of the car. After that though it is a part of the yearly inspection though :-(.

Jeeeeezzzzussss

Damn.. this is loud... Why Megaphone design? Why not just run a 3.5 inch pipe all the way.. I assume it is to slow down the gas on the exit and create some back pressure?
Any dyno yet stock vs this setup?
