YOU guys are coming up with great stuff

very curious!

Yep we have tested the catted header + exhaust, dyno details are in the other thread. And no it did not throw a check engine light. I'm fairly certain that we can avoid a CEL with the catless header as well. I've designed multiple downpipes for factory vehicles that use wideband secondary sensors and had no problem fooling them in the past, but our long term solution on secondary catalyst monitoring is going to most likely be a method of putting the secondary oxygen sensor aft of the downpipe catalyst.

Jason, for those that have already ordered the pipe, are they going to start shipping without the resonator?

Could we opt to wait until the resonator & possibly header testing is complete and then decide on adding a resonator to our pipes? I know I will be getting a header, and I am in no hurry. I'd like to weigh all the factors once testing on the full system is completed.

Thanks

Certainly. We were planning on contacting all of our customers to discuss this prior to shipping. We'd rather have people happy than having to yard parts off down the road to have us rework.

I have the before sound clips in the cabin as well as outside of the car, and will have the after clips shortly. I also have a lot of logged frequency data to share if I can find a method of capturing it to video. May have to call on some of our video editing friends to make that happen, but I'll do my best.

I'm not too far from you guys. Would be interested in coming down to have it installed. Can't wait to hear it when you get the resonators nailed down.

I'll discuss warranty issues elsewhere, but we have been selling our downpipes for the WRX & STi through a number of dealerships who are going as far as pro-tuning their customers cars at local shops, so I'm not terribly worried about dealing with snarky dealerships who want to scare their customers away from modifying their cars. We have had a number of issues with Kia/Hyundai dealerships not knowing enough about the Turbo Optima and Sonata to be able to diagnose issues completely unrelated to a wide variety of parts we make for those cars. In all of those cases we have been able to effectively diagnose the actual issue the car was having (unrelated to our parts) over the phone with the dealerships and in one situation we now have a dealership that puts over $3k worth of our parts onto brand new Kia Optimas for the showroom floor. The bottom line is: we are excellent at corresponding with dealerships in the stead of our customers and we have a number of great contacts on both the parts sales/service side of the shop as well as the technical side. My neighbor is a parts director at a very large Subaru dealership and one of our employees families owns a large Subaru dealership as well.

Yeah no CEL with the catted design at all. Like I said earlier I've got a lot of experience with designing within the constraints of a factory tune and components. A few years back when I was working for a local Mazda performance shop we put an intake on the market that threw no codes, required no tune and made 36ft lb and 33whp. Billet MAF housings and positioning in the induction stream is absolutely critical in tuning an intake design for use without a tune. And generally these designs work equally well with a tune and MAF recal. Same is true of the downpipe and catless designs. Position of the sensor is critical, there's a narrow window of avoiding the CEL codes for catalyst below efficiency as well as a narrow window of avoiding the warmup below efficiency codes - both are on either end of an optimal design. Pull the O2 sensor too far out of the stream, it won't warm up fast enough, put the O2 sensor to close into the stream, it'll won't see enough difference between its reading and the primary O2 sensor reading.

You guys rock. I can't wait to see what you do with tuning.

ANy updated videos of the exhaust with the resonator?

[V1B]

Do we need cats? What about straight pipe? Just curious . Pros,cons?

This won't work on RHD cars I assume?

the standard factory fit downpipe will fit on RHD cars no problem. The one with the integrated overpipe probably won't.

Here's the one you want:

Nope won't work on RHD cars, but never fear, we do have the factory fit design available for our brothers down under. Just had the general manager from Pedders Suspension here for half the day, we can't wait to make a trip to Melbourne. Thinking about making a trip down around Christmas this year or next (Summernats has been a goal of ours for tens of years) and making some more connections for distributors in Australia. Not sure if you followed our work in the last few months but we have been doing fabrication and service support for the Summit Rally Team (also from Melbourne) in the Rally America series. Looking forward to a lot of collaboration and development with them in the future as well. The connections we have made through Will, Ross and the rest of the team have been amazing. Never would have guessed we would have spent half the day with an Australian suspension manufacturer even after doing the rally car work. Word travels fast!

Curious what your thoughts are. Think we should just make it one part on the RHD cars as well? I certainly think so. Seems to be silly to put a flange in there for no reason. Can you email me? I'd love to get some details on the stuff down in that area of the engine compartment on the RHD cars. jason.g@namelessperformance.com

Guessing ballistic louds. Could probably do a resonator instead though! I'm diggin' the idea factory that is FT86Club.com

Hi Jason,

Thanks for your reply. Im on my iPhone now and will send you an email when I go back to work.

Thanks

email sent Jason.

Thanks

Helmholtz is dialed in. Just right. Still has a great exhaust tone and sports car sound, but dead silent at cruise and running around town. In cabin and out of car GoPro vids to follow.

GoPro died when we went to do the out of car, got it plugged in and copying the in cabin onto the computer right now.

Really happy with the way this turned out. Will contact all people who have downpipes on order to discuss.

I think you'll find that it's a band stop filter.

Looking forward to the Go-Pro vids.

Damn it! You're RIGHT! Band pass would only selectively allow the target frequency and eliminate frequencies above and below, wouldn't it!
