How is the power with the Bomiz high flow cats compared to catless?. I would assume that the smell of unburnt fuel will be reduced but not eliminated with that price. But from 1 to 10 how bad is the smell with those cats. Also I am not really familiar with flow coat. What’s the purpose behind it and the benefits ? And how much did it cost youLast edited by Mustafa564; 11-19-2025, 08:06 AM.

I don’t notice any power differences. They also may get better at doing their job after some more miles and heat gets into them. 1 being no smell and 10 being you’re worried about passing out…., maybe a 3.5.Originally posted by Mustafa564 View Post

With the windows rolled up yesterday it was a 1.
From my understanding the flow coating is a slick ceramic product that helps exhaust flow and protects the inside of the header. By ceramic coating inside and out it definitely helps with the heat. I can’t remember the cost. It wasn’t crazy.

but comparing the stock catted headers with your current setup I am assuming it’s day night difference. Correct?Originally posted by theOracle View Post

I’m not exactly sure which differences you’re implying. If it’s sound, then yes the headers are louder. If it’s performance, I’d also say yes it’s a big upgrade. Partially because you need to tune the car which makes a big difference.Originally posted by Mustafa564 View Post
