Hi just checkin, is this MazdaSpeed Sports Sound Muffler (pix here )the 'MazdaSpeed Exhaust' that you guys has been talking about.

There isn't any spec on the site, so does that mean it really doesn't produce any extra hp at all??

Thanks.

 

Does anyone have the JDM MazdaSpeed Sport Sound muffler?

Any tangible benefits for an $800 muffler?

 

It has Mazdaspeed engraved on the tips.

Other than that, it's been reported that there is no performance gain over the stock muffler, although it is just a bit louder.

Buy the Borla. It shows 10-12 HP gain over stock at high RPMs, and has engraved tips too. It's also less than $600.

 

I think I gained 1HP but I know I didnt loose any power...It does sound just a little louder.

 

me personally, i'd say wait till more companies produce them...blitz has one out already, but im waiting for hks or apexi to start selling them...hmmm wonder if they are on sale yet
