catted v.s. cattless dp's

Chewyjr15 · 11-24-2008, 08:44 PM

looking into riss racing because they are local, and have a reputable name. So what is the power difference between the two. I would opt for catless but i dont want to have tp deal with the smell. So can someone who has catless chime in about he smell if any?

thanks

Joey

I just ordered RR Catless downpipes.
So I should know soon, but alot of people are running them.

Riss Racing FTW.

Catless will yield about double the power gains. All world records were set on RR catless DPs. Catted are nice as well and give good power. Just not as high as the catless. The 02 SIM is a must on catless DPs. For catted 95% of the time you don't need an 02 SIM but some cars do need them.

If you leave your stock exhaust on you should have no smell at all. With a fully catless exhaust there is minor smell. I don't even notice it nor do most people.

Chewyjr15 · 11-24-2008, 10:54 PM

from in the car it is not noticed correct? if os than i would be fine getting it. Although I would never pass smog...

coco_m3 · 11-24-2008, 11:04 PM

Have you seen the youtube vid's of RR catless downpipes with stock exhaust?

coco_m3 · 11-24-2008, 11:06 PM

Chewyjr15 · 11-24-2008, 11:16 PM

is their a video anywhere with rr catless dp's and rr exhasut because thats what i plan on purchasing. Btw anthony i am Joey we corresponded via email today.

coco_m3 · 11-24-2008, 11:18 PM

Oh yes, be careful you might need to listen to it everynight before you go to bed, it sounds so good.

The first part of the video is with stock downpipes and RR exhaust, 2nd part is with RR catless downpipes and RR exhaust.

Chewyjr15 · 11-24-2008, 11:54 PM

And you'll be taking extra laps around parking garages, and seeking out those long tunnels :smile:

We have catless pipes in stock, as well as catted, and have a special running on the catted! Shoot me a PM if you want more info!

spr · 11-27-2008, 12:42 PM

Btw per Riss' website the catless give 30/50 whereas catted give 25/35. That's not double the power for catless-

john08135i · 11-27-2008, 05:38 PM

Catless on any turbo car is the way to go...

ki__ · 11-27-2008, 06:10 PM

john08135i · 11-27-2008, 07:04 PM
