Old muffler to new muffler - almost identical in terms of sound, within a 2% difference. Overpipe downpipe, we'll be testing here shortly and have a good opportunity to test it on a stock vehicle as well to compare it directly to the 2.5" version we have been testing with. Give us a week or so and I'll have actual numbers. Sound wise, the larger overpipe downpipe makes a LOT more noise from what we can tell. A few more tests to go to validate all of this.

As for the flange...well....move along, nothing to see here.

Any idea how the header plays out with the early-adopter exhausts?

I'd really hate for there to big a significant difference in the current developments over the ones we picked up last year.

If we sell slowly and don't flood the market, we should still get reasonably good resale price.

So that means it'll be no good with the header? That's pretty disappointing. I was assured when I bought it that it would be the best option for when the header was finally released.

I didn't say that. I was just saying if we "upgrade" we shouldn't sell all at once or we all lose.


We'll probably be fine.

This header will bolt right up to our existing exhaust. No problem. Seriously guys, if you heard this thing at full 3" you'd hang on to the parts that you have in hand right now. It's ballistic. Of course, you throw a turbo in there and the 3" will quiet down substantially. Again, that is why we designed the 3" system was primarily to use for forced induction. We are curious to see how it will perform but I doubt there are 5% of the owners out there who would daily drive this exhaust - it's nice and sweet at idle, but crack the throttle and it'll scare children off the sidewalks.

Again, this header will bolt right up to the 2.5" overpipe/downpipe combo, same outlet location, etc - that is why we have the v-band in the pic is to do differential testing between the two.

Honestly, no clue. Probably lighter than the stock unit though. This one has a bunch of extra flanges in it for testing. While at least one of those will be available optionally as a matter of design, none of them are necessary.

Or they could do a Stage1 (early designs?) that integrates well with the conventional axle-back ( @Tainen 's setup). And this would be a Stage2 header to go with a Stage2 (new gen) exhaust.

I'm going to answer this again just for good measure - not a chance, our goal is to design around our existing system designs. The 3" stuff really is targeted at full race cars where decibels have absolutely no factory in decision making or turbocharged cars that want a 3" exhaust and have the additional muffling capacity provided by the turbocharger.

We're not by any means interested in a) screwing over our customer base or b) developing outside of the range of constraints that 99% of our customers have made very clear (the main constraint being reasonable sound levels).

Thanks! Any idea on power differences? Currently, with my build goals, sound isn't really a consideration, I'm looking for maximum gains possible. I'm really only planning headers, exhaust, and tune for my build (for power, anyway), so I want to eek as much power out of the combination as I can. I fully trust you guys to find that peak combination on this car, I just hope I don't have to start over to reach it.

The flanges are located the same. I'm mainly interested if there's significant power differences. If there are...well, my shit's probably for sale. Though as brought up in another thread, a 3" downpipe is kind of a waste if a 3" overpipe can't be fit.

Got any vids @Jason@Nameless? I want to know what ballistic is to you...

Flange is for testing different collectors and lengths?











(and turbo placement?)
