I figured I would eventually need to do the exhaust so I did a 3" high flow cat with 3" mandrel bent pipe out over the axle and out behind the passenger side rear tire(no muffler). Initial impressions were good, sound wise and spool up and it even feels stronger sometimes however when I g-teched it lost a few mph. Does anyone know what may have caused this. Should I adjust my TPS, change plugs and/or plug wires? What could be the cause, I thought that mod was a no brainer. Oh yeah, I have a 84 T-Type(Hot air ofcourse) bone stock except for exhaust.
