Thumbs up Perrin Subaru Performance uppipe

Quality construction and perfect fit. I had an extra EGT bung welded in for my EGT gauge and it works great. I would definitely recommend this uppipe. It's a great deal for $200.

I would also have to say that the Perrin uppipe is top notch. Quality was second to none, and for the price nothing compares. I bought mine with the original group buy so the $200 price may not be around but many places carry them GRD Performance (GRD_REX handle on i-club) and vividracing, to name a few.

Thumbs down

I have a Perrin up-pipe installed, but it didn't go in properly. I bolted in the top end to the turbo first, and that went very smoothly. But then two things were wrong; first, the end which mates to the exhaust manifold was not square to the manifold, so I had to torque down the hardware pretty tight to make the seal. Second, and most important actually, the two bolt holes on the bottom end of the up-pipe are the wrong distance apart, there was no way the bolts would fit through, so I had to seriously ream the holes on the up-pipe and exhaust manifold out to make room.

If you torqued the turbo to the up-pipe first, that's exactly what Perrin says not to do on his web-site. His instructions specifically say to do the up-pipe/manifold junction first.
Read me

As for your other fit problem, I've never heard of the Perrin pipe having that problem, that's something you should talk to Adam and Jeff about, they need to know if there are these kinds of "QA" problems. It sounds like you got a lemon of a pipe and installed it incorrectly, you really shouldn't have to torque on these junctions. Factory spec is only 28 ftlbs or something like that, over torque them and they have a tendency to leak.

Supermarkus has a valid point, but what I neglected to say was that I originally tried to install it the way Perrin describes, but that was was literally impossible, not just a pain like the way I described. Despite my displeasure, I'm probably going to buy other Perrin parts!

Besides the fitting, any comment on the expected performance of the pipe?

Here is my impression, great product, beefy construction, good thick flanges. Thing fit perfect, no leaks after putting it in. A little increase in noise, but nothing to bad. Had to put mid pipe cat back on other wise I would be running catless (guilty conscience), no check engine light, the provide 2.2 kOhm resistor to put into egt socket keeps that from happening. Turbo spool is faster, and egt's dropped. More lowend power, if I went catless I'm sure I would notice a bigger difference, maybe I will just for fun someday put mid pipe cat elim back on for giggles. Install took about 4.5 to 5 hours. Here are my recommendations, buy extra nuts for the header stud before doing this, they are the same as the nuts for the turbo to downpipe nuts, I stipped two or three nuts while doing this, and yes I used a metric butt ton of liquid wrench. I bought from motormatrix.com, I don't recommend them though I have a write up in the vendor reveiw forum about them, terrible service. But all in all money very well spent, even if just from a reliablity standpoint, so the turbo doesn't get destroyed by broken off cat material, or broken egt probe, the factory one is pretty weak looking, not like the autometer one I have.
Good luck and happy wrenching.

I can't answer for the EGTs... but after my perrin uppipe was installed my spool-up went from 3100 rpms to 2400 rpms.

Great uppipe... and Jeff is a great guy to talk to about the parts.

If anyone is looking for a Perrin uppipe, I have a brand new one. It is the newest one (exact one found on site, shiny metal). I'm asking $225 obo for it. BRAND NEW! I will pay shipping in the U.S if you buy for $225.

i also have a perrin Uppipe, as far as gains go its about 11 whp if im correct (dont quote me i think i read that some where) but more importantly youve removed the cat in the pipe that tends to break up and cause turbo faluire.. so that the biggest advatnge..

later steve
