Get you feedback from people that actually has them. PM Edwin, he has one and no problems fitting it. Edwin will direct you to his friend who also has the Titanioum Greddy cat back on the Evo 9 without fitment issues.
Lets not speculate..

BTW, i think it's worth the money for Ti.

Yea I sent Gruppe S a pm for the Helix Ti.. it looked like it was thicker than the Greddy, thus the weight increase. They also dont have a mandral bender so they have the weld each bend, however the price is cheaper than the Greddy. Don't know if Gruppe S will respond or not, but hey, it is the day after X-mas

If Im going to get a Ti system, I'd like one with a little thicker walls if I could. Also, if theres a chance for better fitment I'm down. Warrtalon, get of your bit, I've had the unfortunate opportunity to see your stuff all over posts even back from July 04 when I search for exhaust stuff. Christ o mighty!
Its cool that you should steer newbies towards making smart decisions with there modding but you can leave some of us alone, especially when were posting in a thread about the lightest exhausts available...
Like it or not Titanium is lighter than steel... now if we could only get some cast aliminum exhaust or something (and not melt), which should be even lighter than titanium!

Ours fits and is the lightest stainless steel system out there. Our catback with our Buschur Racing muffler is only 16.5 pounds, this is 20 pounds lighter than stock. Entire turbo back system weighs in at 23.8 pounds. This is the offroad pipe system and lightweight muffler.
There are some "issues" with the EVO9 exhaust. First off it has a two bolt hanger that goes at the back of the cat flange. This is there to hold the wires for the 02 sensor. The spread on this hanger is not wide enough to get around a full 3" piece of tubing. I don't care who's exhaust you have, IF it is 3" tubing this bracket will not go around the tube. What we do is simply use one of the bolt holes in this bracket and place it back on the exhaust. There is also a tin heat shield that Mitsubishi for some reason decided they needed (I have no idea why). This heatshield has to be removed to clear the larger diameter exhausts. Simply unbolt it and then the two little studs sticking out have to be taken off.
On our catback we are installing the 02 bungs even on the EVO9 systems. When you later install a high flow cat or an offroad pipe you will need a place to put your 02 sensor as stock it is in the middle of the cat. This bung we put in can be used to move your 02 sensor later or for a wide band now. Either way we install it even though it isn't needed now.
The catback is $450 with your choice of our mufflers. The full turbo back is $825 shipped to you.
ALSO, our system is 100% 304 grade stainless steel and mandrel bent.

the only fitment issues one might have with a 9 is a downpipe, but all you have to do is find a downpipe that fits any '05 as the transfer case is the same which is larger than the '03-'04 models with the exception of the old RS's.

In this case, we are talking about AN EXHAUST. This isn't rocket science. You are a fool if you think there are lower margins on these $900 Ti cat-backs than on a $350 stainless steel cat-back. That's absurd. These companies are laughing all the way to the bank because of people like you who think it's SO COOL TO HAVE TITANIUM that they are willing to pay a gigantic markup just to follow some perceived "progression" as you call it. Hey, if you want to be THAT person, then fine by me. The rest of us with some common sense will stick with much cheaper exhausts that provide the same power with only slightly more weight.

Mitsubishi has to use Iron blocks for having one of the highest HP to displacement engines in history. You aren't teaching me or anybody here anything they didn't already know. Which is why i'm even in this thread in the first place. I guess you have a lot of fanboi's on this forum that egg you on and that's why you are on your high pedestal. But teach me , or us for that matter, something we didn't already know. Your true interest isn't in helping people here. It's actually in influencing people in your ways. Which isn't a positive attribute to this or any forum. Saving people money? If someone drops $35K on a car and they want a nicer piece than the local-yocal stainless exhaust for $500. what's wrong with that? Yeah the functionality is there, but what if someone doesn't like the way it looks? So in your logic, you'd marry some 350lb woman because it's functional and cheap, not because the way it looks right? And don't say it's not a proper analogy, because it's totally valid.
