[quote=RPIpower;3816532]Our M3 scoops are $99. As for the exhaust, we will most likely offer 2 different setups. The ST setup would include just the rear muffler section (around $1200-1400). The GT set up would be a more aggressive exhaust which includes the delete of the cats.

Are these the newest version onf the scoops designed specifically for he M3 and if so are they that much better than the red ones released a couple months ago for the 335/m3 that were on sale b/c they were slightly bent.
Thanks looking to order ASAP

Its really not that beneficial other than telling someone you have a "titanium" exhaust. Aside from getting things overseas, working with the material is VERY expensive. All our products are made here in the states so the benefits vs. cost is really not there. For example our full exhaust system for the M5 weighs 59lbs compared to the stock 122lbs.

I don't think they have an M3 specific scoop like RPI either, just a 335 scoop from AFE or something.
believe rpi's are also the same exact scoops for the 335 and m3. when i ordered them from the website, it didn't make make me specify between the 335 or m3....simply grouped them together. Hence, they're likely the same fitment/style for both cars.

We are still working on the exhaust right now. The first few prototypes showed no hp gains and even though the sound was ok. We'll keep you all updated on the progress.

The new 335 and M3 scoops are the same. The old M3 scoops did not work with the 335 (no hp gains).

Thanks for being patient guys. We are going to sell this exhaust as a GT series only. There exhaust system will be broken up in two sections.

Sec 1 header back race pipe (will need our ecu tune to avoid cel): $1224
Sec 2 Muffler Assembly: $1707

Full exhaust package price: $2637.90

Dyno charts will be available next week. You local guys are more than welcomed to come watch the dyno session and hear the exhaust in person.

will the header back race pipe have silencers in it?. Can we assume that it will bolt up to the header and the oem muffler in the same way the AA x-pipe does?

WOW these definately have my interest. Decent price, now all we need are the Dynos!

My car is stored over the winter and this is exactly what I was waiting for ... MORE competition!!! As much as I like the ASR Dyno we havent heard anything since and the full system from AA is just WAY too expensive.

Both sections will bolt up using your oem clamps so they are interchangable. If one or the other will fit another company's exhaust I have no clue. We do encourage people not to mix and match though as the systems are designed as a whole. One companies front pipe might not perform well with anothers rear section. The race pipe will not have silencers in it. Its an all out aggressive race set up.

You'll get dynos..... plenty of dyno session as EVERYTHING we make will be backed up on the dyno and on rear road testing.

Appreciate your honesty on the power results from the exhaust. Were these dyno's with the 1st section, catless? It seems the real power comes from deleting the secondary cats, and replacing the primary cats with high flow cats, any plans to do this type of setup?

I think that dyno chart is for the scoops, not the exhaust.

A little confusion, I'm not referring to that dyno on the scoops, and it appears they made some power. In his post, replying to a question from m3psycho, about the upcoming exhaust, he said the first few prototype exhausts made no power.
