WTB AFtermarket Midpipe
 

Preferably 3''.. doesnt matter what brand but i don't want custom made :| let me know what you have.

I take it you have a shorty DP and are looking for a catless midpipe (AKA racepipe)?

umm no actually, i have a helix catless DP and was looking for a midpipe of a catback exhaust(hks,greddy, idk something like that) not race pipe, something with a resonator cuz i heard they're really loud with racepipe..

Oh okay. I think that's commonly called the rear-pipe. I have a stock one from my 03 WRX if you're interested.

oh yea i see, its also in the middle :D well i need aftermarket one, but thanks.

Yeah, I need a 3" section as well at some point. The "cat-back" but without the "axle-back" on that diagram.

I'm assuming that is what you are looking for as well.

The rear pipe looks like it would be easy as hell to make since its a straight piece.

yea thats what im looking for. :|

yea but then it would be a race pipe, unless you can make it with a resonator, i just dont want something hella loud is all..

you can buy universal resonators from summit.

true but idk.. im not down to get custom made..

If you have an aftermarket DP then you are in to custom made.

hmm.. i doubt it, i have one and it bolts up to stock exhaust nice. and if after markets bolt on to stock DP then it should mount to my after market DP also :?: lol.. that makes sense to me, but idk about everyone else lol..

Your helix DP was custom made and then mass produced. A custom rear pipe can be made and fit just fine. Buy a straight piece of pipe, resonator, and 2 flanges and have a shop weld it together.

yea, that is all true. But i think i would waste more money doing all that then buying one from someone :|

You're pretty much the only person around here who defines custom as "not stock" whereas the rest of us understand he's referring to locally fabricated one-off pieces.

I understood what he meant Kevin M. The problem with his thinking is that he thinks a part that is not made specifically by Helix, COBB, Perrin, etc. is going to have problems or be half-assed.

But that's not what you said. You were arguing a purely semantic point that had nothing to do with what he says he wants.

well this is how i see it, i rather buy one from a company that makes them all day long "aftermarket" even though they are custom made (everything in the world was custom made), than me trying to put pieces together out of some pipes.. but its cool that you have your opinions too.. it doesnt really matter to me because its gonna be for me, you can do your own custom exhaust but i dont want to make a custom exhaust..

That's fine. The only reason I posted what I did is to give you another option.

just buy a catback and call it good!

No man, i want to keep the sti axle back, thats why i want just the midpipe..

If you're keeping a 2.5" axleback, you don't need a 3" midpipe.

yea thats true, well idk then, im just stupid :oops:

might need to go ...gulp... custom.

:huh: custom,,what is that :?: naw jk. idk. i guess i might have to.. or maybe i should keep the stock catback..

Does your DP have a 3" flange or the OEM style donut gasket?

If it's the donut style, http://www.daddysscp.com/dcart4/prod...&cat=17&page=1

3" flat flange: http://www.daddysscp.com/dcart4/prod...&cat=17&page=1

I was thinking the same thing. But at some powerlevel there's theoretically a benefit but the only evidence I have to support that is the fact that the TurboXS Stealth Back is a TBE that replaces everything except the stock muffler. For a stage two 2.0L, for example, the muffler doesn't seem to be a big restriciton (although it does hold back probably 5HP)...but you'd think that the muffler would be a bigger restriciton than a straight pipe given that the muffler isn't straight through like the pipe. Dunno.

The gasses cool and contract as they travel down the TBE. Larger pipes offer less performance benefit toward the exit end of the exhaust tract (the muffler) than they do toward the hot side.

cool. thanks for the links, yea, i just wantet to have the 3" midpipe so it could be alittle bit more flow, i have the sti catback, if thats on the sti its good for me, but i just wanna keep the axle back not the stock midpipe, idk if it will add any power, im sure it wont but still..

My CBE is really overkill since I'm essentially just stage II on a 2L. I have a ceramic coated DWG shorty DP to 3" ID all the way, straight through with one high-flow cat in the midpipe. All I'd need to go to a bigger turbo is injectors, TMIC, the snail, a tune and a tranny fund. :unamused:

yea lol.. you need to get new exhaust, i have 4" DP on top and goes to 3" and sti catback, catless ;) i recently changed my turbo, injectors, ecu, TM :D

I don't need a new exhaust, but it sounds like that STi CBE might be a serious restriction if you've got a significant turbo upgrade.

That whole thing is a myth. It's based the Ideal Gas Law, PV=nRT, except for one slight flaw- IGL deals with closed systems. If you keep your axleback, there is no benefit to replacing your midpipe.

Why?

If he is going from a 3" DP to a 2.5" axle back then he would need a mid pipe like the one in Cody's link.

So you're saying that a bottleneck midpipe isn't any different than a bottleneck before/in the muffler, for example? Interesting. Do you have a source you could link me to?

NT RLY. Unless it's flat flange and just plain won't seal to his stock mid.

Link? No. Just think about it. How is moving the obstruction 30" downstream affecting anything? The gains in that old TXS setup come entirely from the downpipe, because the stock downpipe flange is a much bigger restriction than the piping size of stock exhaust. But once that's gone, if you don't upgrade all the pipe sizing you don't get much compared to replacing all of it.

I don't understand your post.

I don't understand anything anymore :?:

adolfo.. sack up and go custom!!!!! haha!

hahaha.. i think im just gonna try to get an Apex catback, they sound nice.

tanabe midpipe. no cats no resonators.
