This is a FULL race exhaust from the headers back. The price of the set up is $2637.90 which is a geat bargin at $109/whp. This system is also great for weight saving (The full exhaust is about half the weight of the stocker).

The downside is that the full system is not for the mild. Its really designed to make your nuts rattle. lol. We will be doing some dyno runs on just the mufflers shortly.

Sounds good! Sound questions if you don't mind:

1) How big are the tips?

2) Kinda hard to tell from the pics but are those mufflers a circular mufflers (N1-style) or the typical flat oval mufflers on Euro cars?

3) Any pics of the whole exhaust system not on the M3?


4) Cost of ECU tune to avoid CEL? How much more hp/tq (at peak & max on dyno) w/the ECU tune? Or is that last graph w/the ECU tune?

Thx!

quad 3.5" tips

They are slightly oval with single in, dual out.

3) Any pics of the whole exhaust system not on the M3?

No, these pictures wont be posted at this stage. We posted pics of our GT system for the opel gt two months before it was released. 3 companies now have the same exhaust design.

4) Cost of ECU tune to avoid CEL? How much more hp/tq (at peak & max on dyno) w/the ECU tune?

We literally finished the exhaust today so there is no tune yet. Our goal is to be able to give you the full exhaust + tune for about the same price or less than many other companies muffler section alone. We anticipate the tune will be around $1000 bringing the package price to about $3700ish.

I am also working on putting an intro package for board members like purchasing the exhaust and getting a set of ram air scoops for free.


Thx!

How many db at full throttle? I don't want to get black flagged if I decide to track the car.

We havent taken db levels yet. I got a chance to do some dynos with just the rear section today. The gains are 8whp and 8wtq throughout the powerband. I also weighted the stock front section at 39lbs where ours was 19.6lbs.

Its no cats. Its hard to compare whp and wtq numbers against other manufacturers because of the way we test the cars. All our dynos are done on a dyno dynamics and we dont post the numbers unless they numbers can be backed up 3-4 times back to back (no cool down and hood closed). Our gains are done on a bone stock M3 (no scoops, no tune, no aftermarket filters, etc.) We are working on a tune that will give us even more power at this time. Exhausts will be ready for shipping in about 30 days.

Out of curiosity is warranty voided if you have no cats at all ? If yes are you looking at doing a setup with a freer flowing cat that doesnt give error messages (like AA's setup).?

At this time, we do not plan on doing high flow cats. The reason is even with 200cell high flow cats, the performance difference compared to the stock cats are minimal. As for removal of the cats and warranty, you would have the check with the dealership. Removing the cats wont harm your vehicle but you guys all know how BMW can be a very mod unfriendly company at times.
