Amuse Titan is very Amusing
Well in my guess I think the AMUSE TI is on of thee best TI exhaust, because
when you get to a point in reducing chassis weight and have no where to turn, you will then realize that $1500 to discount 30+ lbs is well worth it. In my opinion it is, but thats subjective.
Amuse titan exhaust for 350z

Chris with his Amuse r1 titan exhaust for his dc5 type-r
_________
Amuse r1 titan on a s2k
Hey rs2 should i get the R1 or the Extra Titan?
tell me how you got away with the ticket so when i get the amuse i can get away with it too
iam gussing people are switch their exhaust to AMUSE

People dont care if rust is actually an oxide. People see rust as rust, and oxidation as oxidation. Dont try to confuse the majority just for your own benefit of saving face.
People SS doesn't rust, Titanium oxidizes. Thats not fact, it's just what happens in the automotive industry.
Shielded gas metal arc welding is great for creating nice looking welds. The problem is that the metal you are welding onto changes it's molecular structure and is therefor weaker. See I'm a welder, and I know this. The gas used in shielding typically Argon does a good job keeping the welds from oxidizing before the metal has a chance to bond. The problem is the filler metal will oxized(rust) faster than the metal pipe will.
Welded v/s mandrel in accordinance with flow and restriction is that a welded pipe on a 30 degree angle disrupts flow due to the extreme change in direction. Mandrel is far superior because even though the entire angle might be 30 degree, its actually a bunch of small angles added to form 30. Therefor less of a dramatic change in direction.

i edited because my initial post was full of flames... even if i did go back and edit stuff after "researching" (hah... dictionary.com is research) it's better than most do just staying with their lack of knowledge.
in any case back on topic. i think those exhaust are finely made. love how you can lift an entire catback with one hand.

I dunno about losing 30 lbs on a Ti system. Maybe if both the downpipe and cats were made of Ti themselves, but I don't believe there are any Ti downpipes on the market right now.
A well designed catback in SS are in the 20lb range. Most well designed SS systems are low 20's, so you'd be saving probably 10lbs at most in the exhaust. 10lbs = 1hp. The Ti is bling and has cool factor, but the weight savings in and of itself are not that great to brag about. An extra $1000 for a 10lb weight loss is just not worth it IMO. Hell, just lose some weight, take a dump, or have one gallon less of fuel in the tank. It's all about the same.
Ti exhausts are cool, and I love them, but don't think that you'll be getting any huge weight savings by going Ti over SS.

What about the Magnaflow Ti ?
http://www.magnaflow.com/02product/s...e=Sport&id=240
It is actually manufactured in Japan (some say by JIC) to Magnaflow's specs. So it has the O2 bung and also clears the USDM rear bumper.
MSRP is $895 and it has a lifetime warranty. Obviously doesn't have the bling factor of an Amuse.
Full 80 mm piping (3.15 inch) with a neckdown to 3", weighs in at 12 lbs.
Did well in this exhaust shoot-out, just bettering the Buschur. Only downside I can see (if it is one) is that it's a slip-fit design.

it doe snot neck down to 3" at the cat... it necks down to like 2.8 or whatever...

this is what necking down to 3" from 80mm looks like.

Trinydex,
Regarding the neckdown on the Magnaflow Ti. Randy (a guy on Evom) actually has this installed on his car and he posted that it necks down to 3"; dunno whether that's right or not?

If you want to bolt-up a 3" catback to the stock cat doesn't it have to neck-down? What size does it need to taper to to fit the stock cat?

it doesn't have to... cuz the flange bolt patterns are the same whether it's three intch or not (i think and am pretty sure, cuz greddy bolts up to stock cat).
the reason why the greddy necks down i believe is because you have a hard time finding flanges that are 80mm exactly. 3" is the most common i thinks. but that's just speculation. i'm sitting right here with my greddy ti. and also i have another thread where i'm talkin' with br and i sent an email to mike at roadrace... he measured the greddy it necks down about 2mm which is consistent with what i said about the flanges being 3".

in case you wanted the cold hard facts. https://www.evolutionm.net/forums/sh...ke#post1657467
i have a thread wtih randy saying that
https://www.evolutionm.net/forums/sh...t=exhaust+neck
but it just doesn't look like it... then again... it could be because the greddy tapers to larger than 3"
and i guess the welding might throw off the visual. the greddy's is machined in somehow... not welded in. i guess this is all details.
