[**335i**]

hi

what do you think about those http://www.rissracing.com/catteddpb.html i am wondering to change stock exhaust into BMW » 335i E92 07+ » EXHAUST » RennART BMW 335i Coupe Cat-back Exhaust (resonated) and put Riss Racing 3" Catted Downpipes (coated)

thanks

p.s maybe someone know what is difference between coated and non coated dp?

Downpipes are your best bang for the Buck... Great HP gains, and youll get a great throaty sound with them.

I say pull the trigger and get them... you wont be disapointed.

If you are going to get DPs you might as well get catless. Cost less money and produces more power...its a win/win

Great setup. We've installed RR downpipes on a couple of customer cars with our Resonated and non-res exhaust... SOUNDS AWESOME! Thumbs Up to Riss!

Go with catless dp and non resonated full catback. I'm not saying I have them I'm just saying.

The Catless/catted downpipes with the Renn-Art system sounds very good together. You can choose to go catless with the resonated Renn Art system or even Catted with the resonated/non resonated system. Not too loud, sounds just right!

[**335i**]

u see i afraid that inside a car then sound will be very big i am not talking even when the windows will be open so maybe Catted Downpipes (coated) + RennART BMW 335i Coupe Cat-back Exhaust (resonated) is the best option for a good hp and a sound

[vase330]

How much difference in Hp are we talking about here catted vs cattless? I'd think cattless wont pass emmissions right? If you live in an emmissions strict place, you better verify that you can pass before opting for cattless. Maybe difference in hp is so small as to be mute.

[C-Level]

It's probably a 5-10HP difference when compairing catted vs catless. When you start tuning, though, catless gives you much more potential. There are 4 cats on the 335i, so it's not like you are running straight pipe out. I think it all depends on what you want from your car. The less restrictions that you have in the exhaust, the more efficent your turbos will be.
