What are some good high flow cats that I can get for my 05 coupe id prefer to pay less than 400 and its a plus if they are street legal

 

Technically speaking.... I don't think it's legal to remove a working cat, even if the replacement meets your states emission tests... but I really wouldn't worry about that. The two best I've heard good things about are Crawford and Fast Intentions. You might find some used ones for under that amount.

 

yeah, you might need to bump up your price limit to get quality. Might find some used ones though. Check the Marketplace here on the forum.

 

There's no such thing as a truely street legal HFC.

Fast Intentions, Crawford, & Berks are one of the more popular HFC out there.

.

 

Unfortunately HFC are HFlow because their comb space is wider and thiner and has less platnium so their life is cut short compared to oem cats which must last 80-100k.

Many of them don't last beyond 2 years in a measured emission test.

 

ive seen the berk just under 400

You CAN go cheap but I decided not to and decided to wait.

You can get some test pipes from ebay or anywere and get 2 custom high flow cats welded in.

But honestly you need to know a decent welding place that wont charge you an arm or a leg either.



You can get the test pipes for around 100 and then the cats for another ~120 but then you have to get them welded which is still a big p.i.t.a, the cats have to be small and they are in a weird spot...

I chose to just wait till I have extra cash for the berks.
