So you don't like a better flowing unit because they don't come with a heatshield?Originally Posted by oguitar
When wrapping, be sure not to wrap a flex section; it can cause premature failure...
This is a discussion on up pipe wars within the Engine Modifications forums, part of the Tech & Modifying & General Repairs category; I don't like aftermarket up-pipes because none come with a heatshield. If you get aftermarket please heat wrap it....

Grimmspeed uppipes are $160 new. Locally, a quality uppipe goes from $50-100.Originally Posted by Drews

after getting into it today to fix a leaky thermostat i am now thinking about a full header-up-down pipe-tune budget be dammed, ill just save a bit more. but even headers and up pipe i need a tune correct? im not to worried about heat soak from the up pipe, my drives are really short(3 miles to work) or long cruises at 75-80 for hours.
grimspeed up pipe and headers+tune. can i get 250hp from a 140k motor?

It's not the up pipe. It's the headers. Without the headers the fueling map is fine. With the headers it may need changes.

I'd skip replacing the headers if you're going to be using the stock turbo. The stock cast iron exhaust manifold will provide the best spool and they're not going to restrict flow with a stockish sized turbo.
cool thanks SD. yah,thats got to be a big change in flow. loving the way my car performs already but those factory manifolds are Ugly. im hoping to find a tuner on the west end of MT or denver this summer.
and mainframe too. i had it in my mind it would be easier to get all that replaced in one shot than fight up pipe then replace the headers later. but if thats the case. hmmmmmmmmmm

Yeah definitely skip the headers. The stock ones flow very well and aren't a restriction in the exhaust system.

just ugly and big then lol. maybe its the shielding(which i shall leave intact!) grimm up pipe and gaskets then. seems like they have the best, "i ordered it and got everything!" comments. 2 cases of PB and a weekend lol. i saw a lot of rusty fasteners today. and a tune....might have to roadie to denver but thats awesome,i have a friend down there that has a new MS3 and wants to play in the snow. *snicker*
Meh, they're under the car anyways, so who cares what they look like.
that picture burns my eyes just to look at.
OP i went with a grimmspeed uppipe and gaskets and didnt have any fitment issues. ive heard some others have with GS though..
ohmygod. if i do that with my engine inside the car there had better be a 911 call involved. or you can brand me with it for abusing a stocker. wonder what kind of numbers theyre pulling with it though, has to be real high load/rpm. instead of headers i was looking at grimmspeed's PnP factory iron manifold and crossover combo. that looks like a much better idea than headers. has anyone done a gasket matching on theyre factory iron(old school drumel tool pnp) and had good results? i know this will still require a tune but its a thought. ive done gasket matching on several v8's with great turnout but thats N/A.
that grimmspeed coated set looks nice though.
It was always my understanding that an up pipe added little to no power and I never saw any reason to switch it ?
