Thoughs on single exhaust..?
Right now my exhaust setup is pretty much what everybody else has.. RB header, presilencerr, and two N1 style mufflers, with exception of my catback piping being stock. I was wondering if i should just replace the Y pipe with a single pipe (2.5") instead of the "fake" dual exhaust. I dont see how having it split in two can be beneficial. (besides to look cool)
any thoughts or comments?

Thats odd. Ive had it for quite a while now, since May of last year I believe. The tip does discolor slightly but its nothing a metal polish wont solve. As for rust, theres none on mine........

that just means he has a cheep muffler or doesnt drive it alot and lets it sit outside. There is nothing wrong with single, why would they put a single exhaust on the most preformance rx-7 they have made the 3rd gen?? i would think to reduce weight cuz the only reason for duals is to look good. its true you can have true duals but i dont see why you would do it its like 2wice the weight and the added hp gains would probly be offset bt the weight gains. I have a single cat back right now with gutted cats and you should see the difference in how the car sits, the rear eand sits higher now that o have a light as hell single and took about 3-4 bricks out my exhaust(hunnycomb from the cats)

??? where did you get that information??? you would have less back pressure with true duals if thats what your saying cuz you have less air having to be forced through the same diameter piping.a single you have all the air trying to go out one pipe causing more backpressure. and 87rx7guy my if your refering to my muffler being a 10 dollar muffler it was a $119 muffler not including the piping to the cat. any muffler will rust out expecialy if your in an area where there is alot of salt in the air(the coast) or if its not driven all the time and setting outside in the weather.you can buy the highest quality muffler there is and still beablr to rust it. I cant see how having 2 pipes from the hedder back to 2 mufflers wouldnt be 2 times the weight with single you have one pipe from the hedder back to the muffler. mabe you where refering to a dual exhaust with a y pipe which may be abour 1/3 more weight

I would have gone single for my TII from a performance perspective (not too worried about looks) but since I want it to be quiet, I guess I have no choice then to go with the Racing Beat system.

this comes up every week...i dont understand why pple think that mazda put duals on just for looks. that wouldnt make any sense. they made these cars to be light, so if they wanted to go lighter they would put the single on, but they didnt, they put the duals on for a good reason...if they believed that the single would make the car faster or better handleing then i think they would of done that. i think they might no more than what u think
....jus little bit

its simple mazda put dual to make it quiet, just like they put a restrictive intake on to be quiet and restrictive exhaust manifolds for quiet. the majority of people who buy cars one a quiet car not a loud one. yes ive seen under a 3rd gen there isnt much room but if it was nessicary to put it they would have probly designed the gas tank differently. on 3rd gens i dont think mazda worried so much on how quiet it was cuz it was like $40k and a sports car, most people buying those cars arnt worried about how quiet there cars are.

Two cans = greater volume at reduced velocity.
Meaning if you are running the stock Y pipe, with rice cannon mufflers, it's going to be pretty much the same.
since the true duals are supposed to be "Loud"
Duals are louder, there isn't the exhaust sound waves from both ports to cancel each other out.

I've had my CS Single for about 5 months now and it's never rusted. The tip did get a bronzing color to it but will most likely come off with a cleanser.
On an NA it is LOUD! I set car alarms off. Even After I removed the straight through down pipe and cat and put a Bonez Super Flo on it was still loud just not as raspy.
I bought the CS single cause it was the cheapest and I expected to buy a TII and then I'd swap it over. I don't know if I'm going TII now though(lookin towards a 95 BMW M3 or 3rd Gen RX down the road).
