Nice! Is he in Orange County? I just noticed the 714 area code for his contact info.

I would definitely try to get Stan, Hassan and maybe Nicks input if they would be so kind to help. Maybe digger as well? There are definitely people on this forum with a good amount of exhaust knowledge.

Let's make this happen!

I don't think a section 1 is necessary as most of us with higher HP will be running V1s or ARH which both require a special section 1. I think even Epic needs a special section 1.

A mandrel bent section 2 is really what we need on the market for higher HP cars. Not sure if a single 3.5 or dual 2.5 would be better. Then there is the debate on who needs the cross over and where to put the cross over if you go dual 2.5. For my application I don't even need an additional cross over. I also need it resonated.

The muffler is another hard one to nail down for me I want something conservative, but with a nice tone and sound. Some people want louder mufflers. Some as quiet as stock. It's going to be hard to agree on that one. It should have 2.5 inch piping though. Also drone free is a must like you mentioned already.
I am with you 200%.

A muffler that sounds great, with an exotic, throaty, and refined tone to it, but not too loud. LOUD is not always better IMO. Personally, I don't want a muffler that will out-shout the induction roar from a CSL Airbox. The RE El Diablo, is the best sounding muffler I have heard on this platform. If it sounded similarly in tone/volume but added more performance, I wouldn't be mad at all (totally a stretch though and I am sure not everyone will agree). I love the renaissance movement that seems to be occurring with product development for our platform. This is exciting.

You could basically copy the Bimmerworld design but use a different muffler and maybe a bigger resonator.
That will bottleneck so hard though.

I'd be interested in something that rivals the SS Sport in quality and sound. A nice refined tone for cruising, but a throaty growl when you open it up. And price point matters as well, if it's lower than the SuperSprint, I'm all ears.

Do you have a test car? Have them dyno test different configurations, specifically with X (if it's a true dual) or Y pipe locations. Resonators are a must, but they could getaway with using Helmholtz resonance tubes - it could provide additional gains if they manage to do it correctly. I could dig up the formula to figure it out, but they should be able to manage it

I like the way you think. 83mm tips would be fantastic.

No surprises here, but I am also a HUGE fan of the way beveled, polished SS tips look on this car. It just looks "high-end" and like it could belong on a Ferrari. I think it complements the car well. 83mm would be fantastic.

Something like this:

It would also be nice to have options for different finishes on the tips: polished, satin black, titanium, etc. Personally, I want satin black.

Yup IMO the Eisenmann 83mm Lemans tips are the best looking tips made for our cars. I didn't care for the Eisenmann race as it drones but I have always lusted for those tips. They are slash cut and spaced to align with the rear bumper.

Check it out:

Aren't Helmholtz a little difficult to tune for? Especially with a wide array of header and power setups? I imagine the frequencies for all our different setups will cause problems?

Satin black is easy to achieve on your own if they don't offer it. Just get it Cerakoted.

Have you looked into Milltek exhausts?
