Went down to the muffler man today and spoke with the guy who'd be doing the work. Very cordial and straight-forward. They put my car up on the hoist and we looked it over, wasn't bad at all considering it's been in Alberta the past 4.5 years. Saw the point on the driver's side where the midpipe has to make a small detour (AWD). The guy echo'd much of what you've said, in that other manufacturers also do a "pipe in a pipe", which can result in the inner breaking down and causing issues. In short, he was pretty quick to suggest that doing custom is going to cost a whole lot more than to bring in something like a Tsudo, even if it's just replacing components. He said he could put the whole thing on, including modifying the mid-pipe, in about 1.5 hours.

The axle-back pipes he figures aren't even 2" so even if I go the custom component route that's still going to be there, along with the nested midpipe. Those are mighty sharp turns at the back alright, one of them being nearly 90 degrees. I see what you mean about the X-pipe -- it looks like it went into a hydraulic press! Why didn't they just use regular pipe? Anyhow, at $600 (or even $399 I've seen it listed for) the full Tsudo from what I've heard sounds pretty decent, with the added advantage of being able to try the axle-back first, then if not loud enough put on the mid, and if too loud then simply sell that piece. Have also heard a Tsudo mid with Magnaflow mufflers that sounded good.

Btw, first thing he said was to compliment the colour

Not sure how much custom 2.5" mandrel would be, but considering the cost of tips as well, perhaps this is a solution for the axle-back? Could then just insert the Magnaflows:

Btw, there are several similar-looking resonators in the 2444x 2" series -- how'd you decide which one? Same goes for their 2.25" series, many to choose from. Are they essentially the same excepting for length and inlet/outlet size or is there something else to choose between them?

Yikes, no mufflers on that set up. looks nice though and kinda pricey. You can always do what I suggested and buy online, the separate bends, and a couple of 3ft pieces of stainless, and have the shop weld them on. As for the resonators, biggest difference is gonna be in/out diameter and body length/overall length. Many different options to fit in different spaces. I chose the one I suggested for you based on being the most similar to the length I already had. Just dont go shorter than mine. A few of the TL guys went with the 20inch one which lowered the tone a little more than the 17inch one. Who knows.... if you go with the longest one that will fit, you may be able to run that "no muffler" axle back setup you posted. Would be good R&D for everyone else here... lol

Ha yeah, no way I'm going without resonators or mufflers! Yours is as loud as I want to go. Wouldn't it be tough to find the exact spec bends of pipe and such online, would end up having to piece a bunch of segments together and be better-off just having a shop form them? Or do the shops charge bigtime for the pieces that we can otherwise get for less online?

Chopping out the cats, X, and old reso's for new pipe, X, and reso's in the midpipe shouldn't be that difficult, it was more the straw-like axle-back portion I was trying to figure out. One of the problems of being a perfectionist. Have seen a couple people selling their Tanabes, and maybe a Magnaflow ends up for sale, too, but this setup at least has a nice big mandrel pipe and ends already formed and could just add the mufflers.

So the Walker resonators are for the most part built the same (in a specific series), just differ in size? The longer they go, the more they attenuate but don't really change the tone? So many different ones but there seems to be little difference from the 24440, 24441, 24443, 24444, etc. With no secondary cats and moved X, it looks like we could put as long a resonator as we want under there but maybe there's tighter limitations in our and other cars that I couldn't see. Thing is, we know how yours sounds so I'd seek to keep as close to that as the basis, aside from maybe changing out for more 2.25" (and as $ permits).

Any shop that carries stainless pipe and does mandrel, is gonna charge for it. Companies that mass produce stainless bends, can sell them cheaper... example... http://www.mandrelbends.com/mandrel-...-16-gauge.html
I cant remember the exact one I ordered from before, but I built the entire 4" exhaust on my Camaro with pieces (perfect mandrel bent pieces). I think I spent like $150 total for all the pipe, and had it all assembled for like $75, plus the $75 for the 4" mufflex muffler.
Some of the resonators are listed as "race bullets", but I have no idea how similar they are to the ones listed as "muffler", but yes they are all very similar... 12" body with 2" extensions on each end, 12" body with 4"... several variations. And going longer will deepen the tone slightly more, but also takes out more "rasp", but dont know anyone that has gone extremely longer to see if there is a cutoff or not.
