Big thanks to ehroof and bluecaka69 and clermont!!!
Got home, removed the header which is a PIA without pulling the engine to get a screwdriver on the rear screw, but clamped it down, fired up the compressor and took the cutoff wheel to it and zipppp cut it 1/4" shorter.
Took my time to smooth it inside and out, blew it out with air, and even cleaned with a pipe cleaner. Fastened it back up and wallah ... now the pipe clears so much easier.
Big thank you again ... hats off to you guys!!!
As soon as we have some warmer weather and I can take my truck outside for more than a couple min, I will get some good video
Now, back to the subject at hand ... what is ganja gonna do???
