the only real difference is that the M2's are cast aluminum and the rx7fashion's are polished stainless steel. only matters if your planning on welding on a flange later on.

If I may,
M2's are not *cast* aluminum but extruded Aluminum
pipe with mandrel bends. Aluminum pipe is extremely tough to bend and to weld and hence is reflected in the price or the raw stock. Polished SS is relatively easy to work with and weld.

1 pipe is cast aluminum (primary turbo) and one pipe is bent / welded aluminum tubing (secondary turbo) on the M2 kit. The primary turbo pipe looks too short to put in the multiple bend radii required to use bent tubing. It's also a bitch to install.

just that one is aluminum and the other is SS
i myself was gonna go with M2's since all my other pipes are aluminum but it took them about a month and a half before i got a "it'll be ready next week" that i just decided to go with rx7fashion's pipes. i havent been disappointed

1Bad7, Yup...you sounded like a dick.
As for being the same...ever hear of Extrudehone?
Well it's one process used to remove irregularities and imperfections and otherwise rough interior surface finish found on *cast* components. Extruded pipe has a naturally smooth internal surface...better for flow. Perhaps you overlooked that detail?
Tyson, Thanks for the civil clarification on the two pipes offered by M2.

ok crispy, since i started this im going to finish it
first off we're both right... the primary turbo inlet pipe is in fact cast aluminum. you cant make those kinds of sharp bends by extruding. the secondary turbo inlet pipe is in fact extruded aluminum though because it doesnt need to have those sharp bends. now as far as me overlooking something... i havent. there is absolutely no difference in the smoothness of either of the pipes. the only difference is that the cast pipe is thicker and therefore more expensive

haha, hey sorry jmo87
i can bet that youve got more than enough info huh
i'd say that it comes down to personal preference. if you can then go for the M2's since the intake plenum and just about everything else in the engine bay is aluminum. that way everything looks the same. the SS is very close but it just has a different shine to it. either way they're both good products

I looked at both and ended up going with the rx7 fashion units. Both companies will dick you with oh it will be ready next week... Even worse though the rx7 fashion people told me they had them in stock. So I ordered them... Yeah they were in stock, but they were not polished I had to wait like 2 months before I finally got those "in stock" parts.
I don't want to whine here, but both of those companies suck when it comes to filling orders.

No argument...I think that was adequately clarified

Yesssirreeebob, agree

Yes again. And beacuse it's lighter and cheaper to make. :P

If the internal surface finish of the cast pipe is of the same smoothness as an extruded pipe then it's a mighty fine casting process. Good for M2. But I will always take issue when someone makes a carte blanche statement like calling all cast and extruded material the same. Sorry, my bad.

What is the inside diameter of the pipes?
Thanks guys,
STEPHEN

hey spoautos, sorry about the late response dude
the rx7fashion pipes are 2.5" ID each. im not too sure about the M2's but id guess that they're the same, maybe just a little smaller because "cast/extruded" aluminum is thicker than SS. hope that helps ya

I have the M2. And they are 2.5 in diameter.
I only installed the longer secondary pipe. Now I have a slight internal turbo oil leak. Only happens after a WOT run or highway run using both turbos. Some burnt oil smoke is coming from exhaust. After shutdown.
I have the acordian factory in the front turbo still and the M2 hardpipe for the rear. Would this make a difference?
thanks j
