**Official Aftermarket Exhaust Thread**

5zigen ProRacer A-Spec.

60.5 mm diameter, catback.

I'm the only roadster owner I know of, in the states, with this exhaust. I didn't know what it would sound like, but took a leap and bought it anyway based on information about it on 5zigen's website.

Impressions: It is just as quiet as stock at idle, except with the addition of much more bass. No rasp whatsoever. Minimal highway drone. It really growls and booms when you get on it, without becoming too much of an annoyance. Which is exactly what I wanted. It's an awesome exhaust.

This may be the first place someone has documented their opinion on this exhaust, so hopefully this helps the next 5zigen customer.

off topic but I really want some old school Advan 3 spokes now curse you! might I ask what are the specs on them?

[JSanker]

Get some Advans! We need more roadsters wearing them ;)

They're 16x8 +32 rear and 16x7 +32 front (25mm adapters 4x100>4x114). Currently on lookout for a pair of 16x8 ones so I can have matching shoes all the way around!!

DK wolf, where's my thank you? lol jk.

The HKS sounds pretty good, perhaps a bit loud for my taste.

Here is my custom set up, I have a magnaflow resonator right after the cat, custom bent pipe, to an n1 canister style obx muffler. Pretty simple, but sounds great, and flows even better. It definitely pulls harder throughout the power band. Next step is header and high flow cat, then probably another resonator, because its already extremely loud. Absolutely zero rasp though, just a super deep booming sound.

Here is my Jackson Racing exhaust! I'm pretty sure it is actually for a 1.6, but it works. It hits on the axle at times, I had to remove the ladder brace, and it hits on one of the areas where one of the ladder brace bolts go into....I need to fix that because the occasional rattles annoy the hell out of me!

Took off the magnaflow (left) and replaced it with a RS*R Exmag GT-II catback



I freaking love the sound and how it looks.

Here' my dirty Racing Beat. I love the growl it adds, while staying quiet. And the upswept angle with slash cut tip is perfect.



Cleaned up. (I don't have any real pictures of my exhaust)

[— fwdtamiya —]

That RSR looks fresh!

i should record some video of my bsp/hks shotgun exhaust. with the jr header/cat and the s/c whine, its a nice soundin machine

I've been running a Mazdaspeed setup for a few months now...

Mazdaspeed 4-1 exhaust manifold (type-1) w/ heatshield





Mazdaspeed sports sound muffler (type-1)









The size is not too much bigger from STD



Also put in a magnaflow bolt on high flow cat with it. The mid pipe is a custom job (2 inch, no resonator).

whole system is 50mm/2inch all the way from headers to muffler, with a 70mm/2.75inch exit.
these were the first gen of parts avail for na6ce by mazdaspeed, and by design they are all black. The exhaust itself is made by Yumex (which make the std oem muffler on na6) so I expected it to be a very mild upgrade.

Performance is good, and the sound is very close to stock except with a little more bass. Idle is silent, on cruising speeds its identical to oem but significantly louder at wot. The rasp is still there but there is more bass during decel and mid rpm accel. Low end is lacking (prob due to the 4-1 header design), mid range felt almost the same but top end 5k+ was noticeably better!

(I have since put in a drop in corn*s ecu and low & mid range is back)

The rev matching on downshifts... mmmm gotta love dat sound

[BoBo]

RacingBeat w/ pre-silencer on the mid pipe. I love the tone, it's not obnoxious for everyday driving. A great compliment for NA & turbo setups.
