Does anyone now which was is the lightest and that is not including titanium?

StealthFox

maybe greddy, thats a good question, i know for sure JIC's full titanium setup is but it doesn't qualify haha

nace0088

I know for sure Racingbeat could be the heaviest.I know for sure its heavier even than the stock it replaces.

Sup guys..i just brought my 8 on sat and when i walk in the parts dept. of Mazda, they had the racing beat exhaust on displays. Their price was like 634.00. If they are selling that at the dealer then i was wondering if it's street legal? Any idea? thanks

Mazda dealers in Australia fit the "Hymee" to brand new cars, both demo's and customers' cars

I browsed through the whole thread, and could not find the Trust PowerExtreme mentioned anywhere, so here goes. The Trust PE Ti can be found here Trust PowerExtreme Ti, and is probably one of the best upgades. Costs a bit more than the SS ones, but:

a) produces some nice HP (around 7-8HP according to Trust/Greddy), and
b) is VERY lighter than the stock or ANY SS exhaust out there.

Compared to any other SS exhaust or the stock (all of them weigh around 17-18Kg), the Trust weighs in at 3,7Kg We are talking about -15Kg weight saving just by swapping the exhaust....

As for noise levels, this exhaust is rather deep and throaty, but the noise increase is very, very modest. At high rpms you may not even notice you have an aftermarket exhaust (except for the backfiring )

StealthFox

its also very very expensive(around 700+ bux) and shipping from japan on a catback woudl be VERY expensive as well. Greddy makes a US version of one of their titanium exhausts which is simularly priced, except you can actually find them here in the states since its a USDM product and you don't pay over a hundred dollars to ship it over here

The Ace

Actually it's much more expensive than that. The retail is around 1250$, and we (in Greece) end up paying 1350E (~1500$) including shipping. I guess the price will be the same for the US. However you can't blame the company for the price, since titanium is a much more expensive material than steel

My whole point was that a titanium exhaust more or less justificates it's price not only by the increase in performance, but also by the weight reduction. The SS exhaust might give you the same HP increase (~5-7HP), however only the Ti ones will also provide a 15Kg weight reduction. Can't beat that....

If you can find the same exhaust/design in titanium by a US company, then by all means go for it. However I couldn't find many other models, just the JIC one, which is much more expensive...

can anyone tell me about the RE-Amemiya one?

Tim Benton

11 pages and we know little about the weight of the systems posted above.
Hymee - 15 to 16Kg
Racing Beat - heavier than stock
Stock - ??

Does anyone know the actually weights of the systems or was this exhaust summary really only for sound and price comparisons? Since we all now know that most cat-backs aren't going to add much in the way of HP, it WOULD have been nice to know the weights of the exhaust systems. Similar HP gains but the weights of the systems aren't...ie Racing beat being heavier than stock.

I'm getting the Mazdaspeed dual-muffler exhaust installed tomorrow. Are there any special break-in procedures that are recommended with a new exhaust? I don't think there is, but I wanted to make sure.

Thanks!

Ensure you bounce it off the limiter before you side step the clutch.

Drive by the nearest Police station and rev the **** out of it.

Then drive around their parking lot and repeat.

You forgot to tell him to then pull up to the front door and get out and wave to your new audience.

Sweet, I like these breakin procedures.

As long as you break something, then I guess any proceedure achieves the desired outcome.

Hey any feedback on that Mazdaspeed dual muffler sport exhaust?

I'm looking to do the same upgrade but don't want any truck sound.

Has anybody gotten that installed yet. Looks promising from the spec. data. Nice stainless steel cans!

I installed it last week. I love the it!
I was originally looking to buy the Racing Beat Exhaust because I didn't want anything too loud.
I decided to get the new MS exhaust because the price was right, and someone posted a sound clip. It didn't sound like it was too loud.
After a week of driving with it, I can say I'm very happy with the sound.
If you real get on the throttle, it can be very loud, but at cruising speed on the freeway doing 80mph in 5th/6th gear, it's very quite. When I leave my house in the mornings, I keep the rpm's low, and it's pretty quite.
Once it warms up, it is definitely louder at full-throttle.
I planning on doing some in-car video at different cruising speeds do people can get an idea of what it sounds like.
