perfect rotary exhaust
 

stock, sounds lovely, and just a hair of raspiness after 7.5k rpm.

i want it a bit louder, but still keep the tone. a lot, a lot of aftermarket exhausts for our cars make us sound like the ricers we so despise.

to achieve this, i'm thinking about getting a catback, and only using the muffler part, so i still have the very small piping before it gets there, will i achieve anything with this?

and to kill that raspiness at the very high rpms, could i just weld resonators along the exhaust path?

dude if you keep the cat on you shouldnt have raspiness at all but magnaflow is a nice exhaust not ricey at all a lil more deep

keep the very small piping

What part of your exhaust is 'very small'?

i've heard quite a few 8's with the cat on, and i can't tell the difference between em and ricers.
the 2.5" diameter piping before the muffler, and after the cat, and if it helps, keep the exit of the muffler 2.5" too, and weld on new tips.

i had an idea for using slp loudmouths, its not an actual muffler, basically just resonators welded to tips.

SLP loudmouths on camaros/vettes lol , those sound sick. Not sure what it would do to an rx8 though :S

the rotary engine is raspy by nature. you arent going to get rid of it

hymee claims his does what you want. i wish there were better sound clips.

I have the Hymee cat back and have been very pleased with the results.

please post sound clips.

I'm too old to be posting here, but I have tried numerous setups. The best sound is the Racing Beat Porter (Header), Mazsport Dual Resonated Midpipe, and Racing Beat REV8 Catback Dual Exhaust. It is the most extreme exotic deep throated note I have heard to date out of a NA renny. Pure joy to experience

i just installed the greddy sp2 it sounds great not to loud nice and deep

The perfect rotary exhaust has a down pipe in it :lol2:

Here is my car with hymee exhaust/racing beat header/mazsport midpipe/stock airbox with green air filter. Sound pretty nice

that is nice.

go to youtube look up mazdamaniacs exaust test clips. the HKS one sound the best i think, nice and deep even at high rpms

but it's single sided, isn't it? looks retarded if you ask me.

god that neighborhood looks boring.

car sounds nice though. +1

You are right about the boring neighborhood. Too many seniors....and cops are really mean. The first year (make that first summer) I moved here I got pulled over no less than 5 times and some of those were just to ask stupid questions....one of them was "Is this your car?"

good good set up, very nnice, suprisingly nice, very exotic/sporty...too bad i can't get headers, or a mid pipe trying to be eligible for b stock.

beers :beer:

I'm not sure if people read this thread... looks to me like he only wanted the muffler to pair with the stock piping...

it doesn't have to be only about me. right now we have the suggested hymee, with evidence. very good. not raspy. loud and not annoying

I chose the Mazdaspeed dual exhaust exactly because I didn't want to sound like a ricer. It doesn't sound loud at idle, just a nice purr, and it gets louder when you floor it, but if you don't want that you should just get a Civic :P

Thanks Anthony for the comment. I really like my set up but I will be installing turbo(esmeril kit) very soon. On the set up that I have there is no drone on high way and it sounds really nice inside the cabin as well. It louds when you want to and calm when drive normally. It got my GF stamp of approval!

In my opinion the perfect rotary exhaust has NO hint of raspiness at all. Raspiness sounds ricey and horrible. It sounds like you couldn't afford a real exhaust. They key to not sounding raspy is in the size of the muffler(s). The larger they are, the less raspy they are. The deeper the tone they are too. Mazda's Lola race cars from the early 80's have lowly 12A engines but gigantic mufflers. Those are the meanest sounding 12A's I've ever heard. You don't have to have 4 foot long mufflers but they do need to be bigger than 6" in diameter and you should at least run a presilencer. That should keep then raspiness away.
