Does any body have the Rev8 exhaust and cat replacement pipe?
If so how loud is it and is there a major difference vs just the exhaust

Its insanely loud.

Even in the car people always comment on how loud it is. Outside it sounds really really loud, especially from behind the car. I'll post a vid in a bit

I will take this as a chance to get one of my questions in as well. I have heard that removing the cat from the 8 makes the car stink.....Why? doesn't that stink come from the cat letting you know that it is going bad? I had the cat removed from my cougar when I had it and had no problems there. I would greatly appreciate if somebody could explain this for me.

The cat is what removes the stink. http://auto.howstuffworks.com/catalytic-converter.htm

I actually heard, or read on this forum that the exhaust was quite. Is the Pipe the loud part or both?

straight pipe makes it loud

I guess I will be loud does any one in the north have some extra ear muffs?
lol
My turboxs is almost as loud
what is a canzoomer?

MazdaJeff

Thanks. Just wanted to confirm.

Canzoomer unit was the first piggyback EM unit for the RX8. It was basically a greddy emanage blue with the proper wire harnesses soldered onto it so it was plug and play. Also he sold it with some RX8 specific maps loaded. Basically to get much out of it you still had to tune it yourself. He's a vendor on the forum. You can check there for more information. You're better off getting the int-x or emanage ultimate if you want a piggyback EMS, which I assume you already have since you have a picture of the sweet sweet PEttit SC sitting in your engine bay.

I get so confused with exhaust system pieces. What is the difference between a mid pipe, straight pipe, catback, cat converter, and all that jazz? Why do I see some systems using mid, and some using straight, or some are just mufflers, or without catalytic converters. Break down please.

shaunv74

stock exhaust= cat converter+"catback" exhaust (which is muffler and associated piping)
catback=pipe and muffler downstream of the cat converter.
mid pipe=straight pipe=cat delete pipe=taking out the cat and replacing it with a straight piece of pipe=not emissions legal

its got rice written all over it

Ah, thanks Shaun. So whats the difference between Racing Beat's two different systems besides the price?

Their race catback is a single outlet exhaust that is louder and lighter than the REV8. They don't make many claims that it gains much more horsepower than their street exhaust but it's lighter. If you're looking for a street application the race exhaust will probably be loud and annoying for you.

The mid-pipe they sell is also for race applications. It is a replacement for your Cat converter. It is also not street legal. But for racing it removes the restriction the cat. creates and frees up a little more HP and weight. Again it's also MUCH louder.

My advice for a street application is get the RP supercat high flow cat and the REV8 exhaust. If you really want to go with removing the Cat then get a mid-pipe with a resonator (which Racing beat also sells). This is basically a small straight through muffler in place of the cat. that keeps the sound under control but doesn't reduce the flow very much.

If you like a louder exhaust the Greddy SP2 exhaust is louder and still sounds really good.
