I can do Db testing with my Radioshack sound meter though.
I have heard a true straight pipe racing and it sounds AWESOME.
Loud..but makes the car sound WAY meaner.
Street use on this car sometimes so we had him put the bullet in.
Takes some of the raspyness out of it.

Well I know you and Joe wont make the SD tour next year, no way you will be under 93db. :D

Mike, what kind of muffler is that? Burns Stainless painted black? And what happened to Shelbi getting a straight pipe?

No kidding. Mike that exhaust is FUGLY. God. Don't you know anything about exhausts?

Our custom quad-exit exhaust is almost finished. Yeah, it's 52lb heavier than stock and loses power but it looks TIGHT.

(This is not particularly directed at you, but all those thinking loud exhausts on auto-x cars.)

You know.. joking or not, that's exactly how clubs lose sites....because someone cruises past sound meters, but break the limits elsewhere on the course. Many sites are now imposing sound restrictions on their sites.

If you *know* you're going to be too loud for a site that has sound restrictions, stay home... that region doesn't need you there ruining it for them just so *you* can have some fun for a few minutes.

You want to keep this sport alive in places that you visit? Meet the rules of the region. They're there so others can continue doing what they enjoy.

The best place up here for auto-x (Devens, Ma) has a sound restriction. 1st time you break it, you're told to fix it. If it's not fixed on 2nd run, you get sent home. Not fixed 1st time out next event? You're sent home. And this continues.

I don't know...Although Mark's pretty much goes straight with a turndown at the bumper, it looks pretty similar. The Isley design 18" Borla on mine is louder than his.

Moderator,

Please rename this forum to: RX-8 Comedytition (Razzing)

It would seem to fit better lately.

Looks very easy to make. I'll be interested to see the dyno results. have you done, or will you do, a base dyno of your car?

Uh, you aren't the one that is going to be driving it around on a daily basis.
Really, after driving it just once it does sound ALOT better (less raspy) than the Celi straight pipe (even with the cherry bomb on the end).
Crusing on the freeway I could not even tell a difference.

by itself, not likely, but combined with a minimum weight base model, lightweight wheels, tool/floormat/etc. removal, low fuel tank, empty windshield washer tank, and some other minor savings it can all add up. Some of the Stock class RX-8's are coming in in the low 2800# range, that's quite a bit less than Mazda's 3009# specified weight

fwiw Mike, 0.00x difference is likely more of a driving situation than 20#

Could. Auto-x is usually won or lost by tenths or hundredths of a second. So any power or weight advantage could get you that extra .1 seconds needed to win.

while we are on the subject.
Any idea how much a sport + appearance package model weighs? And how much weight could be lost by removing appearance package.

Kinda a moot point, since the driver is a fatty and is about 75 lbs overweight...

yeah mines 1/2 the weight of Mike's and probably quieter too :p but it probably cost 3x as much

Talk about to loud. Barbara's car has a system like mine but uses a shorter Borla, 12" instead of 16", she got a tickect yesterday for being to loud. I drove it a few times at our natls warm up yesterday, had to try out those 28 series Konis , it is painfully loud in the car even with a helmet on.

A few pounds of weight in a street car isn't going to affect the way your car drives or performs. On a race car however where they are trying to get any little advantage they can, 20# is definitely something to address.

And they do State emission control compliance testing along with tuning. How convenient!
