I notice there are no HP/TQ benefits listed on the website for these. Do catless downpipes alone provide any HP/TQ benefit by virtue of reduced backpressure? Or must they be paired with tuning to get any increases?

Also, what happens when it is time to get the car smogged for registration renewals? Do the pipes need to be switched back to stock?

Are these catted or catless? Sure looks like a cat on the upper piece that connects to the turbos...?

Id be interested in giving them a try for that price if they are catted. Been catless for the last year and am thinking of changing it up.

Gains will vary between cars depending on factors like pump vs race gas, stock or tuned ecu, etc. Generally, they gain around 30 hp/tq. Yes, the downpipes will increase HP/TQ without a tune but to fully utilize them, you will need a retune. Yes, to pass smog (depending on where you live) you would need to reinstall the factory exhaust.

The downpipes are catless and for off road use only.

Whats with the larger diameter chamber right after the turbos then if it isn't a cat?

That particular section was designed to pass visual inspections!
