B&B Race Cat Pipe question....
 

Does anyone have a B&B race cat pipe on their RX8? If so I just want to know how you guys like/dislike it? How's the sound? Any horsepower increase? Any info would be very helpful since I'm in the market to buy a race cat...

you two might want to get together.

Your close
 

I have the B&B cat back with racing pipe. It increased performance, but it was some what loud. :rolleyes: I was concerned I would blow out the neighbors windows when I fired up in the mornings. Put in a glass pack and that toned it down just right. :D Tell you one thing, it does not sound like the RX8 you drive from the lot. :cool:

One thing putting in the B&B system revealed because you have to take out the cat, the RX8 is set real rich for US imports. I am still tuning it back. Man I get some of the most spectacular tail pipe flashes when I run up the RPM and let it drop. On the track, I get a lot of attention and thumbs up with my dragon fire display on the straight-aways. :D

it totally replaces the cat, right?

yes it replaces the cat but has no catalyst. just a very nice pipe.

sorry if this is a silly question, dont our cars need catalytic converters to be road legal or am i missing something. I was thinking of gettting a system like this but didnt realise there was no cat at all.

yes you do need a cat.

beers

bit of sarcasm? ;) lol

So with this system, technically the car isnt road legal?

Correct. Run a straight pipe at your own risk!

If you want something that is legal, then check out a high flow cat.

no sarcasm at all. sorry if you missed what i meant. the answer is running without a cat is illeagle on pubic roads.

beers

Ah right, no worries.

Suppose its a risk people take :) thanks

...i still want one!

You can standa foot from the tail pipe and the fumes will rise up your lead and make your eyes tear. The RX8 is so rich. $$$

do u still get the 'flames/sparks' when hard on throttle and lifting/changing gear if you have the Hi-Flow cat?

^^^ Yes, you do.

which has a better hp gain b&b cat back pipe setup or high flow cat and b&b muffler?
