the_marquis78 Posted February 21, 2007 Posted February 21, 2007 I have a Perrin UP for the LGT and was about to install it until I talked to a mechanic who works for the local subaru dealership. He asked if it had the flex point in the middle or if it was just a solid piece. The Perrin UP is one solid piece and he told me that he has installed several of that variety and they have all cracked in the middle. He told me that the only way to go is getting an UP with the flex point in the middle unless I want to waste my money. Can anyone confirm or deny this? Additionally, I know lots of us put on the STi UP on the LGT, what is the form of the STi's UP? Is this guy full of crap or do I have the wrong UP?
rao Posted February 21, 2007 Posted February 21, 2007 The Sti uppipe has a flex joint. The guy is not full of crap. Search, this is a hotly debated topic. I would not install an upipe that doesn't have a flex section. Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT
the_marquis78 Posted February 21, 2007 Author Posted February 21, 2007 I've tried to search a few times but I always find things that don't really apply to my specific question and I swear I'm not computer retarded...anyways, thanks for the input
lvethesnow Posted February 21, 2007 Posted February 21, 2007 auto speed has a nice up pipe that has a flex at the bottom so that the exhaust has more time to straitin out. there web site at www.autospeedperformance.com they have nice down pipe and cat back too History does not entrust the care of freedom to the weak or timid People sleep peacefully at night cause rough men stand ready to do violence on there behalf
the_marquis78 Posted February 21, 2007 Author Posted February 21, 2007 I actually already have a Cobb DP and the exhaust already done so the UP is just the next step I suppose, thanks for the tip
the_marquis78 Posted February 21, 2007 Author Posted February 21, 2007 last question then, is the STi UP just as good as the ones made specifically for the LGT? Should i save money by getting an STi UP or spend more?
rao Posted February 21, 2007 Posted February 21, 2007 All uppipes that fit the WRX or STi will also fit the Legacy. IMHO you will not find any material performance differences between any uppipes. Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT
Scooter Posted February 22, 2007 Posted February 22, 2007 Here's a very recent thread: http://www.legacygt.com/forums/showthread.php?t=53042&highlight=flex Seek first to understand, then to be understood. In other words: SEARCH before you post!
suds2250 Posted February 22, 2007 Posted February 22, 2007 I've run a crucial up-pipe (it's solid, no flex) for 10K miles, never a leak and no cracks. The only crack to worry about is what that subie tech was smoking. 335HP/360Tq VF-22/1820 clone with Meth
the_marquis78 Posted February 22, 2007 Author Posted February 22, 2007 that thread was the perfect one, thanks! don't know why I couldn't find it before
waverunner Posted February 22, 2007 Posted February 22, 2007 I have ran my perrin- up for about 11 months with no problems at all, like mentioned before no difference in performance just preference,both will do a good job. Perrin is made of 321 stainless, pretty solid piece.good luck.
