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?

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.

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

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?"

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

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.
