Amuse R1 Titan Extra STTI Exhaust - Review (pics/vids/dyno)
 

Hey all,

So as Mike@370ZTUNE posted in a different "teaser thread", I went ahead and bought the Amuse R1 Titan Extra STTi exhaust. I think we all know who Powerhouse Amuse is by now, so I won't waste any time. I had pretty high expectations for this exhaust, and it's certainly lived up to my expectations of power, sound...and taking a huge swipe at my wallet :facepalm:

Thanks to:
Hunter/Mike@370ZTUNE for getting me this exhaust and putting up with my pestering,
Casey/Rich@AEPerformance for setting me up with a kickass dyno / local shop, and
Daniel/Randy@Performance Associates for doing all the dirty work, and humoring me while I hung out for more than four hours. Stand up shop that, despite their obvious bias to domestics (:p) I will be going back for future dyno pulls.
Rounds on me, guys!

Off to Performance Associates. My Z is a bit out of place...

Makes the stock exhaust look real ugly.

Yay! Installed! No adjustments needed (nor really possible, it's all pretty much set in stone...)

Still on the lift...took me 30 minutes to wipe it down to make sure it was fingerprint / oil free. Dammit Mike, you made me paranoid :p Daniel (the installer) had a laugh at my expense too

More to come when I find a better video camera...because mine really doesn't do this exhaust any justice at all...

NOTE: Look @ the after dyno graph (fuzzy as it is). Had a really weird blip at the end of the dyno run. The exhaust...wasn't tapering off yet...:icon14:. Also, not sure what the effect is, but I did modify the secondary piping from standard Amuse layout (see post below).

Still, conservative, we'll call +15hp, +8tq, per weather corrected numbers. In case you wanted to know, this was done on a Mustang dyno.

Using the same review system as my old F.I. thread... (see Tony? I'm still plugging for ya, bro!)

For those of you who do not know, the R1 Titan Extra STTi uses a single 3" main pipe split into 2" secondary pipes. Since my future big mod will be a supercharger of some sorts, I asked Amuse to enlarge the pipes as they saw fit to support forced induction. So I have an atypical 3" -> 2.5" pipe setup with 4.5" tips. Note that my exhaust "sound clip" and dyno results may differ from yours!

Also note: the R1 Titan Extra STTi, as it is sold, does NOT include a midpipe. Hence why I'm stuck with the stock Y-pipe for a while.

Anyway, final impressions:

Looks: 9.5/10. It's Amuse. AMUSE! The quality of the welds had the people at Performance Associates (and myself) drooling. It's as if they were machine welds. Meticulous attention to detail in each and every segment of the exhaust. Amuse has the ability to burn out the entire tips blue if you want, but I thought it'd look kind of weird on a red car. So slightly burnt tips it is! I can't write enough about how dazzled I am by how this exhaust looks. Added bonus: Amuse guaranteed on their website that the new exhaust is no lower than stock. Well...yes, it's not, and they've still managed to show off a good deal of the canisters. No, it's not a very 'original' design, but certainly great to look at. Now if they could just use a little thicker titanium on the tips...

Installation: 10/10. No adjustments were necessary, Daniel had the stock off and the new Amuse exhaust on in fifteen minutes. I then proceeded to wipe down the entire exhaust for the next 30-40 minutes to get rid of all the fingerprints and oils. Yay for being nitpicky!

Sound: 9/10. Well...I've been through the F.I. exhaust (hope you're liking that exhaust Danny,wherever the hell you are), and as it's the most popular exhaust here, the question pops up 'How do they compare?' If I can use a terrible metaphor, the Amuse exhaust is a classical symphony to Fast Intention's rock concert. Both are great, but they're for different crowds...lol, what, it works!

The main things I've noticed with the Amuse exhaust:

• At startup, the exhaust immediately makes itself known with a nice throaty roar.
• At idle, you barely know it's there. Seriously, it's quiet in the cabin again, which was weird for a while, but I've grown to really like it. The exhaust will happily burble every so often, but otherwise it's perfectly content to sit there and puff away. If you're looking for something that howls even when you're idling, look elsewhere.
• The sound is 'cleaner' on the Amuse exhaust. It starts docile, then unleashes an insane storm when you stomp on the accelerator. The sound is higher than the Fast Intentions; more of an 'exotic' than F.I.
• CONCLUSION: Simply put, they're two different beasts, and (provided you have the financial flexibility to be considering both options) you can't go wrong either way.

Weight: 10/10. Added this category as a 'kudo'-point to make. The stock system, measured at Performance Associates, weighted it at a whopping 46 lbs. 46 lbs, not include the Y-pipe. Holy ****! Here's what Mike sent me with the Amuse stuff (with packing material on it...)

5.8 + 13.6 = 19.4 lbs. Subtract that away from 46, you get...uh...26.6 lbs weight savings. I think I did my math right...but anyway, it was really light.

Performance: 8.5/10. Haven't driven it enough to get a feel for it, and the ECU hasn't had time to settle in yet, but the car is definitely kicking again. Check out the dyno above (as of this post, not there yet, but I'll get the graphs up soon!), the car was maxed out on the test and still hungry to make more power! I can hear Jeremy Clarkson and his trademark, "POWERRRRRRRRRRRRRRRRRRRRRRRRRRR". Now then, about that supercharger... (just kidding...for now!)

Final Thought: I love this exhaust. I also reserve the right to update my posts once my midpipe gets in!

Feel free to ask any questions you guys might have :) Thanks!

:tup: Da, damn! Holy high-end exhaust!

Nice Pics...can't wait to see Vids and Dyno results...Is everything from your headers to Y-pipe still stock?

Hopefully you got great gains bc I actually think the first vid sounds better or at least more throaty.

Aesthetically speaking I give that exhaust :tup::tup:

If you look at the placement angles, he was closer to the Z in the first video (more throatier is to be expected in the first vid). This sound is pure sex. Look at those cans, man!!!!!

a single pipe? oooh... interesting, in for dyno results!

Sick faylun!

:tup::happydance::yum::yum::eek2::postwhore::drivi ng:

looks and sounds good :tup:

I need my dyno results. :D

wow these dyno results will go a long way in answering the question what's better a true dual or a single larger pipe. Phelan how big is the diameter on the tubing for the single mid pipe?

Nice! Congrats, Phelan! Now you can show up to your cosplay parties in uber style man! :tup:

cosplay is cool...... nice stuff phelan!!! waiting for dyno numbers..
