Does anyone know which exhaust system flows best. I know that sound is very important,
but Since I have the Greddy Turbo and concerned about the restrictions of the turbo which
will also quite the exhaust system. I currently have the Mazdaspeed Exhaust and I'am
wondering if maybe it more restrictive than other systems out there, I also have the RP high
flow cat, which I love..

Any info out there about this.....

speaking of good exhaust flow on aftermarket exhaust systems is the new racing beat single exhuast exit good in flow? because i see it maybe exiting on the rear right? if so -- is this the best exit i think maybe a left exit would be better flow wise but im no expert so any out there seen the new racing beat single exit exhuast? and would care to express their opions on it?

someone should update this thread with new(er) clips. I.E the new ms exhaust. And clips with hi flo cat or midpipe. Seem like those thread about soundclips of midpipes and hi flo cats are popping up every week.

MS Exhaust VS Tanabe Super Medalion Hyper Spec.

I am trying to decide between getting the MS exhaust and Tanabe Super Medalion Hyper Spec. There has been lots of good press about the MS system, but little info on the Tanabe. Does have any advice.

Thanks in advance.

i don't have either. But search for username modena, he has the tanabe exhaust fitted on with soundclips available. There is also clips of ms exhaust lurking around.

Power wise like mention many times both would not yeild any noticeable gains so decide on sound and style.

Thanks for the tip. I checked out Modena's post and it does sound pretty sweet.

I think I will end up getting the Tanabe. It is a more expensive, but the tips are bigger (100mm vs 90mm), and the angled-tip complements the design to the car very well.

Thanks again...

Yep. Something nice about 100mm angle-cut tips

Cheers,

Trying to be unbiased...

From my own experience, and if you are after some more noise... The RB system is louder than stock, but quieter than the "Hymee".

Cheers,
Hymee.

Originalk MS exhaust was single can and looked identical to OEM. New version is twin can design.

From what I have heard it seems that the Racing Beat is one of the quietest aftermarket exhausts, but one of the best looking, IMO.

The new MS exhaust lets you know that there is something under the hood, although I have never heard the Racing Beat I am going to say that the new MS is probably louder. This is based on hearing others opinions.

Here is a link to a picture of the originial MS exhaust:

not sure but i dont think mufflers take off nearly as much power as a catalytic converter. one thing for sure is your car will be loud as a MF

hmm, i've really been looking forward for a B&B exhaust or borla (i for one want a little shiver down my spine when going over 5k rpm

). the thing is that i was told borla was bad quality. some days later, i was told B&B is even worse then borla. would someone be able to tell me (perhaps personal experience) how much truth is behind these words?
