Installed last week and can’t get enough of it!
Great Product! Install was easy and shipping time was great. I don’t usually right reviews but I had to for this one. Was throwing code P0420 on my Evo X for months. Previous owner did a CAT delete. Bought a HFC from another company and it didn’t get rid of the CEL. I was recommended this product by the shop that tuned my car. Installed this catted test pipe last Sunday and no more CEL! Thank you so much ETS! Will definitely be buying from you all again!
Great quality product and straight forward installation. Car also now passes emissions! Wouldn't hesitate to buy another.
Sounds amazing you can hear the pops and bangs just with the cat, but once pair with the ets open dump down pipe and the ets v3 extreme you got a dream sound.
I already had a high flow cat. Kept throwing check engine code. This took that away and also doesn't stink after driving it. Awesome product!
QUESTIONS & ANSWERSAsk a Question
Can I order the (extreme) decatted version
We no longer offer a catless version of this part, we only offer it with the GESI catalytic converter.
Will this work with a Tomei Cat Back Exhaust?
Yes it will.
Should this work with an ams downpipe or would I need to purchase a ets Downpipe?
This will work with the AMS downpipe as well as any other downpipe that terminates in the stock location.
Hi, just purchased the GESI. Is the cat their High output rates for 500whp, or is it their Ultra High Output rated for 800?
We use the ultra high output option.
Would the GESI HFC pair with your V3 exhaust?
Yup! We designed our GESI HFC to be a direct replacement, so it will work with any downpipe/catback combiniation that mimics the factory design.
What are the difference between the 3 of them?
The GESI version has a GESI High Flow Catalytic converter in it which is for emmisions.
The regular catted version just has a 200 cell high flow catalytic converter.
The Resonated option includes a 3" bottle style resonator to help eliminate drone and offer a slight reduction in noise.
The straight through option is just that. Straight through test pipe.
Does this item come with a new gasket, or does it have to be purchased separately?
Gaskets and everything you need to bolt it on the car.
Would this pass in California emissions?
These are not CARB approved.
Hi there! Was wondering what the difference was exactly between your HFC and your GESI HFC. Thanks!
Gesi claims to get the car through emissions testing while having no effect on flow at all. It is just a higher quality catalytic converter
Does this Test Pipe work on a Mitsubishi Ralliart?
Yes, this works on the Evo X and the Ralliart.
Does it require a tune
While the vehicle may operate and drive with this part installed, a tune is stongly recommended for proper vehicle operation and optimal power production.
What is the total weight?
This test pipe weighs 9.3lbs compared to the stock weight of 16.5lbs
