Last night I installed a summit racing O/R h pipe on my 89 GT with shorty headers. Install went pretty easy until I went to install 02 sensor on pass side. Bung is facing starter with no room for sensor to fit. Are these pipes that poorly designed or is mine just a screw up? I'm calling tech line Monday and if it's that poorly designed I'm going to ask for money back instead of trying a second and paying for shipping again.
