**Riss Racing** 3 inch CATTED downpipes (Prototype)

Adam@Riss Racing · 03-27-2008, 09:34 PM

Hi everybody,

The long awaited Riss Racing 3" CATTED downpipes are available now!!! Here are the pictures of our Polished and Ceramic Coated!

1. POWER? Catted downpipes will still create tons of power. Our cats are located near the bottom of the downpipes. They have custom Metal Substrate Catalytic converters which flow from 3" to 2.5" smoothly. The reason for this is to continue to build boost up top with 3 inches of flow and putting the cats in before the sensors so we don't have a CEL.

2. DYNO? See above.

3. AVAILABILITY? TODAY.

4. 135i? Yes, it fits the 135i!

Pictures on our site are not updated yet. They should be updated this weekend. They are available for purchase!

NEW UPDATE:
Videos and new pictures below!!!

Is it worth it to change them out every two years for inspection?

If they are catted they would pass emissions. Also, in Texas they test through the OBD2 port so the BMS o2 simms would pass you for emission purposes....

McLuVan · 03-27-2008, 09:47 PM

i would buy these

It is a PITA but doable from what people say.....

Back on topic. The DPs look great....

Check your laws locally on how they smog. If its through the OBDII, the 02 sims with our Riss Racing Catless DP's will pass.

much better like the previous thread, thx for info Adam. Looks nice, curious about performance compared to RR catless ones.

Not here to stir any fires. We know the first release was a tad bit long

. Not trying to make the same mistake twice. We'll open a new thread for new goodies we bring to the table for you guys.

stuff in there still looks cramped. cant wait to see the gains/price here! im just
trying to get the most power and still pass emissions!

What cardboard stuff are you referring to????

I think that sounds about right. Should net pretty good gains though. Hope to get some custom tunes for our catted dp's too.

I did not mean the original RRDP thread. Just the one which - as it seems - got prolly deleted from here, prolly because of the pointlessness of the first post followed by similarly meaningfull responses. Make threads like this one and U'll be good. Make other quality product like your catless DPs and U'll be even better. Make them in time and U'll step over your shadow

cn555ic · 03-27-2008, 10:07 PM

Well with these catted ones, I think there is no need for group buy needed to produce them!!!

doba_s · 03-27-2008, 10:08 PM

sweet ... i really hope it will be available before the bimmerfest ...

Soni · 03-27-2008, 10:26 PM
