I was wondering about the mazdaspeed exhaust how would that be will there be a gain is horsepower or which other exhaust is good but not to loud I want to stay close to stock sound or something with a nice sporty sound not a raspy or deep sound?

 

Use the search toolbar my friend.

 

Borla

 

If ur looking for quiet ms is a good choice so is jic. Shameless plug, mine is for sale if u want to buy one...

Listen to the clips on this site, and decide for yourself.

 

SR Motorsports full cat back with high flow cat with resonator

 

RX8Store which uses Magnaflow cans.....very nice deep sound. (Opps, you said no deep sound?!?!?) Well, like most, this exhaust is pretty quiet at idle but really comes alive with the right foot. I added mine about 2 months ago and love it!

You're gonna get a whole bunch of opinions on this thread. It would be best if you could find a few folks in your area and listen for yourself.

ps - from what I've heard, the MS exhaust is not much different than stock.....seems like alot of money to spend. The HP gains with ANY cat-back system are gonna be minimal (like less than 5hp regardless of the manufacturers claims). It all about the sound!

 

Have you thought about changing the tips on your stock exhaust? If you dont want to go that route, then get the RB, I had it and it is pretty quiet compared to HKS, Greddy, and even the Borla which is on the quiet side also.

 

Does anyone know why the tips bronze on the RB exhaust? Seems to me it would have something to do with the material it's made from, especially if others do not do this.

 

The fact of the matter is that no exhaust will give you huge gains although you will get some. Many of them are very comparable to each other. Which one is best is purely subjective and open to opinion. It is hard to get an accurate idea of how one really sounds just by listening to a sound clip on a computer. You're going to have to find a way to hear some in person to get a good idea and then decide from there. The ones that I think sound good may not sound good to you and vice versa.

 

I just like the look of Hymee's and the fact that the tips do not discolor is what is selling me (I have yet to purchase an exhaust for my still unpurchased car!)

 

clips on which site?

 

This site. I searched for: exhaust clips and voila

MS Is quite and then racing beat
but I luv my greddy sp2

 

I would suggest the Racing Beat muffler...that way you can ensure you are not reducing your HP.

This is from the Racing Beat website...

http://www.racingbeat.com/FRmazda4.htm


The following table lists the measured power gains from various aftermarket components. Testing has been conducted on the Racing Beat engine dyno with both pre-production and production Renesis engines.

1. Intake – enlarging the oval inlet to the factory air box - +2 HP (this modification eliminates the VFAD intake duct.).
2. Headers – approximately 4 HP peak power gain.
3. Mufflers – muffler & connecting pipe - 2-3 HP.
4. Removing the muffler from the car (engine) – about 4 HP.
5. Remove catalytic converter and resonator from the engine completely, and replacing with "cat" replacement tube – max benefit 8 HP – regardless of what muffler is used (or even no muffler).

"The muffler "off" will yield about 4 HP, with a very loud exhaust note. With it "off" the car, the noise is unbelievable! We find 2-3 HP peak RPM maximum improvement from our exhaust, or any competitive system that we have tested. So someone can see from these numbers, it is quite difficult to get a lot more HP from this engine. The max potential with a header and race exhaust would be around 10HP."

During the prototyping of our RX-8 exhaust, we kept hearing claims of rather large HP gains from other aftermarket exhaust systems. Since we were not observing gains anywhere near some of these claims, we decided to obtain two of these systems for our own reference. One of the systems performed as expected and produced around 3 HP, as did the RB prototype unit. However, the other system did not fare as well and actually produced less power than stock!

Since it is our policy not to "bash" or downplay competitors products, nor do wish to embroil ourselves in a controversy over HP claims, we will keep the brand names of these other systems confidential. Aftermarket manufacturers test products using various methods, and as you can see the results can vary!

It has been our recent experience with normally-aspirated Mazda applications that significant HP gains from an aftermarket exhaust system are hard to obtain. Mazda is simply doing a very good job with their exhaust systems! In today's horsepower hungry marketplace, it is unlikely that a significant amount of horsepower would be left behind in an ineffective OEM exhaust design. But hey, that's just our opinion!

 

I love my RB exhaust. I've had it a year now and still turn down the stereo to listen to it zoom up to redline. It sounds good, sounds expensive, I call it the "poor man's Ferrari" sound. The stainless tips don't bronze up much at all anymore. When I wax, I use an SOS Pad on them and they really shine. It gets all the black junk off the inside edge with little effort. The Borla and MS are canister like the stock exhaust. I prefer the duel muffler look. Plenty loud when hot, but quiet when I'm driving my mother or my boss and am focused on being respectable. Lots of posts on them, and I have yet to see someone who bought it that didn't like it. Second choice is Borla, just a bit louder at low speeds, but the folks who bought them like them too. I've never heard the others in person, but they are not as universally praised on the site. Hope this helps.

 

You use an SOS pad on your exhaust?

 

Any comments on HKS Legamax?

 

oo legamax is one nice exhuast...

 

hks... and also about 1g.. i would get that but damn expensive for an exhaust IMO.
