Would the material used and welds be able to withstand the high temps if I had one sent to Swaintech to get coated? Got this done with my RSX's Comptech shorty header and it significantly reduced engine bay temperatures.

Also, what gains are expected from an SI without any ECU tunes (stock)?

Do you still have any catted downpipes available?

I’m going to order one next week.
Yes, we currently have them in stock ready to go.

We offer ceramic coating however you are welcome to send the part out to be coated on your own. The part should be able to withstand any coatings.

I would expect around 7-10WHP and 7-10WTQ on a stock tune running 87.

Any info on what brand and model number cat was used for the rv6 catted. Trying to determine if I should go catted or catless.

The cat is a custom made part. It is 300CPSI and made of high temperature Feceralloy foil. Much more robust than anything available off the shelf.

Thanks for the fast response. I might just be going the RV6 route due to the heat shield cover.

If someone buys the catted downpipe and confirms it passes the annual sniffer emissions test, I'll buy the ceramic version.

RV6, do you have a completely stock vs catted downpipe dyno to confirm there's no loss of low end torque or hp?

@RV6 Any updates on if a catted downpipe for the 2.0 is being planned?

I can use a few extra HP's, but would also like to pass inspection so I'm keeping my fingers crossed.

Thanks!

We will dyno the catted version soon. There is no doubt the catted version will make less power. However with the high flow core the losses should be small and is a good compromise for not having to deal with smell.

No updates yet on the 2.0 base stuff. We are a bit swamped with production.

I’m eagerly awaiting your 2.0L cat version. This car is my daily and I would love to know if it will pass smog with the high flow cat. Any pictures of the downpipe with the heat shield attached? Does it cover it enough to pass the visual inspection too?

In another thread RV6 mentioned they're currently searching for high flow core that will fit the 2.0 platform, so it sounds like it's still in the design stage as that update from them was posted a week ago.

I have the thermal r&d exhaust with front pipe. I'm looking at getting the catted downpipe but wondering if the bottle neck will be any issue. So it would be 3" to 2.5" downpipe to 3" front pipe and exhaust. Or am I better off buying a true 3" downpipe? Also the thermal front pipe, were it meets the downpipe is 2.5" and rest is 3".

It wont matter if your donwpipe is 3" or 2.5" since your exhaust necks down to 2.5" at the inlet.
