Default Best Uppipe?

What is the best uppipe available? Cost is not a consideration here. I just want to know if there is one true champion above the rest - or are there a few contenders?

An uppipe is an uppipe. Period. They will all perform the same. Fitment on the other hand varies from brand to brand. Since you say money is not an issue, by all means by the Vishnu uppipe. Has a flex pipe, and looks pretty. =) And from what I hear fits really darn good. Perrin's are supposed to fit really well. I went with a Godspeed, and had to take it apart 4 times to get it to stop leaking, but the Godspeed is one of the cheaper ones you can buy. Now that my uppipe isn't leaking anymore it works great. =) But the main concern of having an uppipe is getting the cat out of the pre-turbo exhaust, causing spool up time to increase and a good drop in EGTs. Horsepower isn't really gained, what is gained is more efficiency in the turbo, a smoother, broader powerband.. you hold boost longer to redline. Spooling sound will increase, but it sure is a pretty sound.

if cost does't matter, don't settle for anything less than a vishnu.

sometimes i find myself peeking between the airbox and my boost controller just to get another look at that thing.
it's so nice... i miss being able to hold it in my arms

Have a Nice Day? unless vish has changed his design..

friend of mine went from perrin to vishnu.
old was 304 new is 321 stainless.
it did not have flex joint.
flanges 3/8" to 1/2", in other words fit and finish
were "better" on vishnu than perrin.

but another friend has pde, 304 with ceramic coating.
but this one has bracket to use factory heat shields.
also high quailty of fit and finish..

if had 300 bills to spend on up-pipe, it would have to
be a coin toss between vishnu & pde.

my 2 cents.

Most uppipe problems (leaks) come because of installation problems. I haven't heard of one failing. An uppipe is just a pipe. Unless you are very mechanically inclined, I would advise either getting it installed by someone who has done a number of uppipe installations or by enlisting the help and advise of someone who has done several.

I have a PDE and installed it myself.

I got it because of the coating, heat shield bracket, EGT bung, and price.

It fits great and I have had no problems.

BTW, all up pipes are not the same. Early Godspeed pipes had fabrication and quality control problems. From what I have read here they have fixed that problem. I believe most of the mfg's have worked out ther bugs by now and you are probably safe with any brand.

If cost were no issue I would go with the STI pipe. It looks stock and is proven design under some pretty stressful conditions. Also has very good heat shielding.

Installation is key. Torque sequence. And, I would also use some sealant, at least around the header to up pipe joint, just in case.

I agree with the comments where "uppipe is an uppipe". The heat shield braket is not necessary since you can just use 3 - 4 bolts to hold it firm (Out of 7 total). I have godspeed Uppipe and TurboXS turboback. I had to alter the heat shield to fit the HUGE downpipe.

I would spend money on buying the downpipe along with the uppipe. This will make your installation easy since you would have to remove downpipe to install UPPIPE anyway... It would save you time for installation... (IMHO, you really want to get rid of back pressure in the TURBOed car... So, you will most likely want to get the downpipe after installing the UPPIPE anyhoo....).

Also, follow perrin instruction. You must torque the pipe in right order to avoid leak... (This really helps to align the pipes correctly to avoid leaks).

Just my 2 cents.

Dan from PA.

How close to stock does the PDE look with the heat shields in place?

I need my warranty, so I'd like to be on the DL with my mods.

Thanks

It does not look stock.

There is no heat shield arount the PDE up pipe. If you are looking for it, the difference between the aftermarket and stock is readily apparent to a "trained" eye (Inspector observes, "Isn't there suppoed to be a cat in that pipe?").

The only one that I know of with a stock looking heat shield is the STi model, hence my suggestion that you go with the STi. I don't know of many folks who can tell the difference between the stock and STi unless they have seen both and know exactly what to look for (You, "Yes sir, inspector, the cat is beneath that little heat shielding. No, I don't think it comes off. See the SUBARU stamped in the side.").

The dealer will be able to tell the difference. Several that I have talked to will not give you a problem because of this replacement (unless of course you mangle the EGT probe). One even suggested it be my first mod, and offered to buy and install it for me. Another has covered a bad engine even with the up pipe in place since it did not contribute to the damage (and, no, I don't give out names to protect those who are on our side).

Again, you said money is not an issue. Buy the STI.

I also agree with Dan. Get the downpipe at the same time. Saves labor. I didn't .

I also agree about the Perrin instructions. They are the best if you are going to do the work.

haha. a subaru mechanic will know, no matter what uppipe you use. but it won't void your warranty, unless you are dealing with a retarded dealership.

There's been talk recently of cutting out the cat and welding in a piece of pipe. Then you could replace the heat shields and look 100% stock. Have yet to hear of anyone doing it.

If aftermarket is your thing, I vote for Vishnu or PDE. MRT has a flex joint if you find that important. Vishnu has expansion collars, not a flex joint. PDE is nice because it has the heat shield bracket.
