Thank you
Thank you
i got a RB race pipe, everything bolts right on. that pipe replaced both the resonator and the cat. its really smelly now, but the sounds is nothing. its just alittle louder and more raspy. on the day that i installed it, i could tell noise was louder, but after the next day, i don't even notice it anymore. its not even as loud as stock mustangs or other american muscle cars. i only saw one cat on the car when i was working on it though, so i don't know what u mean when u say both cats.

i am getting some funny noises too, but more like metal rubbing and sqeaking noise. at first i thought it was my brakes cuz it would go away when i brake. but my brakes are ok. i think it only comes on when i step on teh gas. sound familar? i'm gonna jack on my car to check anyways but just want another opinun.

The first impression was after 4k it sounded almost like the pipe was vibrating and contacting metal creating a very ricey sounding buzz. I at first started to wonder if I left something loose so I went down and rechecked everything...but that was not it. I then took it to a shop and got it up on a lift thinking that it needed a hanger...but the only place that comes close to hitting is where the midpipe and header meet. In that area the clearance between the transmission and pipe is very tight...so I assumed that perhaps its vibrating against the transmission. I then did forum search after forum search and the only things I found were...it could possibly be the factory system heat sheilds vibrating...or its a "normal" noise which was once muffled by the factory cat/resonator which is now coming out due to the midpipe....

I had cel concerns about getting a midpipe too. This website sells O2 simulators and guarantees them to work or your money back. Not a bad deal. I was told to get the $25 simulator and was re-assured that it would work for an RX-8. I never had to try it out though because I ended up going with a high flow cat because of inspections. Here a link to the site:

I have the same cat pipe as you eviltwinkie...
Can you shoot flames though? Because for some awkward reason I can, and I don't get any CEL... Revving in nuetral is what let's me shoot the flames though...
Did anybody remember that RX 8 Backfire thread in the performance section? It just dissapeared!
I think I'm just going too buy a video camera and link too my own movies... That'll take a month...

Its all in how hot you get stuff...after a spirted drive hovering 6-9k for a few minutes...things are pretty toasty and a quick blip of the throttle or high rpm shift will ensure success...
