i will be purchasing a greddy turbo kit for a 00 integra gsr and am looking to upgrade the downpipe to a 2.5 inch one since the one with the kit doesn't fit 00and01 integras. I am looking for one with a flex section and an 02 sensor bung in the factory o2 sensor location so I don't have to mess with the harness. Also I need it to bolt up to the factory converter. Does anyone know someone that makes this pipe that will fit with ZERO modifications? Also it has to retain AC.

 

i just visited ktellar.com but it only lists downpipes for the sohc greddy 15 g kit. I need one for the 18g kit.

 

greddy owners help me out!
