Mat_Mandangle Posted October 28, 2019 Share Posted October 28, 2019 About 5 years ago I had an STI uppipe installed and now it has a crack in it. Pretty significant and stinky exhaust leak, coupled with some white exhaust fumes (on a cold day) coming from the hood. I originally went with the STI uppipe because I had read that they fit the best and resist cracks better than Invidia etc uppipes. I've been searching thru the forums here to find an updated list of good uppipe options, and am wondering if the best option is finding an OEM gutted UP, or should go with Cobb or something else? It's getting nice and snowy in Colorado and I'd rather not drive with the windows down/die of exhaust fumes any longer... Also, I probably won't be able to get this fixed for another few weeks - is there any potential harm to the engine/turbo with waiting to fix this problem?

shralp Posted October 28, 2019 Share Posted October 28, 2019 I’ve had years of use and abuse to both Perrin and Cobb options with great results Link to comment Share on other sites More sharing options...
cryo Posted October 28, 2019 Share Posted October 28, 2019 stock sti/06+ wrx/07-09 LGT is going to be the cheapest, I go with grimmspeed otherwise due to the lifetime warranty.

ashwinearl Posted November 3, 2019 Share Posted November 3, 2019 I just found a crack in my Cobb up pipe. It is about 4 years old. I am going to go Grimspeed for my next one. Can a cracked up pipe contribute to running rich at WOT? Link to comment Share on other sites More sharing options...
HDTurbo Posted November 3, 2019 Share Posted November 3, 2019 Both my Invidia UPs cracked. Replaced with GS; has flex... Link to comment Share on other sites More sharing options...
gimpydingo Posted November 7, 2019 Share Posted November 7, 2019 OEM or GS. I went GS since it was cheaper at the time. Works great and came with gaskets. Link to comment Share on other sites More sharing options...
