05legGT Posted October 22, 2010 Share Posted October 22, 2010 im installing an autospeed turbo back in a few days. Do i really need to gut my up pipe? I am going stage 2 but I am not hard on the car and I only drive it on weekends. Is my up pipe cat really going to disintegrate nd get lodged in my turbo? anyone on here still using the catted up with aftermarket turboback?

Max Capacity Posted October 22, 2010 Share Posted October 22, 2010 Up pipes are cheap enough, I didn't take the chance. I have catless up/dn. Turst me. You'll like the feel in 1st gear. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

forayzor Posted October 22, 2010 Share Posted October 22, 2010 just like max capacity said, while you're installing the turbo back you may as well install an uppipe. theyre inexpensive, and gives you the peace of mind by not worrying about the cat. plus its less restriction to the turbo, which quickens spool times. they can be found at fred beans for pretty cheap Link to comment Share on other sites More sharing options...
almostinvincible119 Posted October 23, 2010 Share Posted October 23, 2010 Quick question (and I'm sure its a noob one to boot), and not to derail this thread from the OP's question: I've seen Uppipes on eBay and such that say they will fit 05-09 legacys and nothing else. But then, some of the WRX/STI uppipes say they will fit the legacy. What gives? Are they the same bolt patterns? Thanks guys for the help. Link to comment Share on other sites More sharing options...
Max Capacity Posted October 23, 2010 Share Posted October 23, 2010 Sorry, I'm not a big fan of Ebay. I rather buy from someone that supports this forum or the guy that Tunes my car. For the OP when you remove the oem up pipe, you'll understand. It weights about 15lbs and is very plugged. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

scoobydoobie Posted October 23, 2010 Share Posted October 23, 2010 ALL of the STI UP will fit the legacy. Link to comment Share on other sites More sharing options...
GTTuner Posted October 23, 2010 Share Posted October 23, 2010 Honestly, gut your stock pipe. It will last alot longer than an aftermarket pipe. Link to comment Share on other sites More sharing options...
SubOperator Posted October 24, 2010 Share Posted October 24, 2010 ^^^ That or get 07-09 LGT uppipe - same fitment sans the cat.

Pijanica84 Posted November 5, 2010 Share Posted November 5, 2010 If you get a 07-09 uppipe or an STI uppipe do you still need a tune? Link to comment Share on other sites More sharing options...
Heedz Posted November 5, 2010 Share Posted November 5, 2010 No tune needed exceptyoull throw a code until you use a 2.2k half watt resister in the get sensor plug Link to comment Share on other sites More sharing options...
almostinvincible119 Posted November 5, 2010 Share Posted November 5, 2010 I think I would tune. Actually, I am going to. The uppipe really didn't help my power out all that much. Just the pull from above 4k in 1st gear. Link to comment Share on other sites More sharing options...

OutbackXT05 Posted November 6, 2010 Share Posted November 6, 2010 Either go the cheap way and gut it. But make sure EVERYTHING is out. Or I think the uppie can be found as cheap as 30-40 dollars on ebay so I've heard Link to comment Share on other sites More sharing options...
SubOperator Posted November 6, 2010 Share Posted November 6, 2010 No tune needed exceptyoull throw a code until you use a 2.2k half watt resister in the get sensor plug we just kept the sensor connected and zip tied it to harness such that it does not hang around. zero cost.

LosAngelesLGT Posted November 7, 2010 Share Posted November 7, 2010 im installing an autospeed turbo back in a few days. Do i really need to gut my up pipe? I am going stage 2 but I am not hard on the car and I only drive it on weekends. Is my up pipe cat really going to disintegrate nd get lodged in my turbo? anyone on here still using the catted up with aftermarket turboback? I dont understand. Subaru stopped using catted UP in 07+ because they recognized a major design problem/flaw and engineered a solution (air pump, etc). Catalytic converters work because they GET HOT. They do not work when they are COLD. We all (hopefully!) know that when things get hot they EXPAND and when they get cold they CONTRACT. Metal fatigue is produced and a lot of air is blown through the fatigued metal. If you drive your car far enough that it comes to temperature and then let it cool off you are being destructive to your catalytic. It is my understanding they CAN start coming apart in as little as 60k miles (not our uppipe cat specifically but catalytic converters in general). (Clearly some metals are specifically tempered and designed for repeated, low-temp heating such as cookware). Link to comment Share on other sites More sharing options...

All it takes is an un-noticed miss-fire to over heat a cat. And all it takes is just a little piece of metal or carbon to put a turbine, that turns at 100,000 RPM plus out of balance. This will destroy the bearings and after that it is all down hill. "Belief does not make truth. Evidence makes truth. And belief does not make evidence."
