Ultimate Racing High-Flow Ceramic Cat | 2003-2006 Mitsubishi Evo VIII-IX (200031)

I got this so I could pass emission on my Evo 9 it had a trst pipe so I needed a cat it has a tune on it with bigger injecters and is runnimg rich but even so the cat let me pass wounderfull lie and I don't feel any loss in power compared to the test pipe as well before the o2 sensor broke because it was hitting the body of the car but with the new cat it now doesn't it hit and has way more room great product only thing is it did take 9 business days to get to me

I gave 2 stars on my first review and I would like to take that back! I thought the cat was rattling only after two weeks of use but when I took it out I found a nut inside which is what causing the rattles. I have no idea it got in there. It does not seem to have come from the cat because the honeycomb and everything inside is intact. Whatever it was, I am happy that I found out about it and it isn’t because the cat got faulty. I should not have rated it 2 stars without checking the issue first. Clearly a fault on my side. Anyway, I’m glad I got this sorted out and I’m loving this product. Exhaust has toned down a bit which is just what I expect it to be. Good quality and build!

Bought the Ultimate Racing hi-flow cat great fitment and reasonable price. Bolted up perfect.

I got tired of the fumes from having no CAT on the car so I decided to buy a high flow cat that looked stock and a 3" , looked around and found this one that had what i was looking for so I bought it and once I received it it looked amazing in quality and the price wasn't too bad, it took two weeks to get here cause I guess it ships from Canada but I didn't mind it, the only thing that didn't fit was the hardware it comes with cause it about half and inch too short to bolt up, other then that it fit perfect and it did quiet down my car a little bit which is a plus for me

Exactly what I wanted and the fitment was perfect! Thank you Maperformance
