Which Exhaust System???
Just got my MazdaSpeed exhaust installed.... haven't really tested the car and see the performance...
What kinda exhaust are u guys using (if you replaced it)? And how is the performance comparing to the MazdaSpeed unit??? Thanks guys!!! |
from what many of the guys here say, the aftermarket (GReddy, RB, REAmemiya, etc) net very little perfromance gains (2HP or so) because the Mazda engineers did a good job with the stock exhaust. Even the Racing Beat guys admitted that they aren't able to squeeze that much performance from their exhaust (+3HP) like they were able with the rx7 (+10HP). I think some people found that the aftermarket ones gave LESS performance than stock. From what I know, the MS exhaust isn't supposed to give you any performance gains but does give you a more throatier growl. I think you're probably the first one I know of that has it.

Looks like I pulled a noob and didn't do a search. Here's a link with the discussion on the MS exhaust and a clip of the MS exhaust sound. I guess the only performance gain is that it is lighter than the stock, so you are saving weight.

RB just came out with a racing muffler that saves some weight. You may want to check it out

well the MS exhaust does sound a bit better, and according to the tech's that not only the MS unit is lighter also the structure inside is better-flow than stock!
|
I have the stock catback with the rp supercat midpipe. It is not much louder than stock, but the higher flowing supercat definitely adds power.
|
I have a Borla myself. Sounds amazing, and does seem to have a LITTLE more top-end pull than with the stock unit. Could just be a placebo effect, but that's fine by me. ;)

COOL! Well I've tested a couple highway runs on this MS system, and it FEELS like giving me more kick on the high end from 5500 to about 8000 rpm.... and I love the sound since it's deeper but not annoying!
|
where did you buy your Mazdaspeed exhaust from?
i'm tempted especially if Canadians can buy MS parts from Mazda dealers now. |
After doing some research I figured that the most power/response cost effective (my car is leased) mods would be: RP supercat (395USD) and a better flowing air filter, I went for the one Pipercross UK makes (50USD). The only benefit to an exhaust system is a better sounding engine note as well as more aesthetically pleasing bigger exhaust tips.
However I was planning on keeping it I might put an exhaust system that would complement the supercat. |

I like the sound the G35 and nissans make, anything make the 8 sound like that

you cant get the G/Z sound with a rotary.. you need a v6 for that... you must hear a Z with ano exhasut sounds fabulous....very deep and howls .. while the greddy for the 8 sounds more throaty and 'fast'.. |
