I got my parts from g8only fit pretty cheap (I think) and began to install today. It took me about an hour and 15 minutes to take the factory stuff off and install the hesders. At that point I figured I'm home free... after another 30 minutes of messing with the connection pipes and x pipe I decided to stop. I had friends coming over and needed to drink. Now, I only have 15 years experience working on cars and I am working under jackstands so I know it's not ideal but, is it necessary that the slip fit connection between the x pipe and connection pipes is .00000001 mm? I made that up. My point is, why is it so tight? ****- it's supposed to slip in and then be able to move around so I can fit it to all the pieces and then tighten it down. I have to give all my strength to try and "slip" the connector pipe into the x pipe and then I can't maneuver it to get on the header. Needless to say it's fun. Hopefully I'll get it on this week. Other than that the parts look great.
