High flow cats .....i have a racing beat cat back exhaust, and I'm looking to replace the cat with a high flow.....I'm not going with the racing beat replacement pipe cause it causes the engine light to be illuminated. Any help or any idea of which might fit my exhaust. Thanks

 

Bonez supercat (rx7.com)

 

^^^ yup!
I have that exact same setup, LOVE IT!

 

RP Supercat. Had that with my Racing Beat exhaust & it sounded awesome together.

 

Ahhh okay thanks alot and this will not illuminate my engine light, and are the horses worth it, im planning on getting the Cobb access port so Im thinking this will help it run better.

 

It's just another part of NA tuning. Will it give you a ton of hp for the money, not really. But the question is what NA accesory will give you really any bang for the buck. But it won't compromise your reliability like some of the other (i.e FI) stuff might.

 

I know that the RB exhaust is considered to be on the quieter side...but how much louder does it get with the cat??

And does it actually CHANGE the RB sound or just make the RB sound louder??

 

it gives the exhaust more 'grunt' at the lower rpms and it's a bit louder at open throttle

 

Doesn't really change the RB sound, just a little more. Little more grunt on the low end, little bit louder on the high end, whereas there is almost no difference on the low end between the RB & stock, but a bit louder on the mid/high end. Perfect to me. When you drive by the cop he won't be able to tell the difference, but it sounds great when you open her up.

 

i'll have this combo this weekend after i install my RB exhaust.. -yay-

 

I went from
RB Intake + Stock Cat + Stock Exhaust
to
RB Intake + Stock Cat + RB Exhaust
to
RB Intake + RP Supercat + RB Exhaust
to
RB Intake + midpipe + RB Exhaust.

The best sounding was probably the Intake+Supercat+rb exhaust
I was still getting a CEL though so I went ahead and decided to go straight pipe in prep for the eventual turbo application. Now I LOVE the low end, but it gets a bit raspy at high RPM. It's pretty loud.
