M4wd&Fabrications

my exhaust bender with swedging / shrinking is my new favorite tool. 


used the auto bend feature to make two identical bends today for first time.  was awesome to just push a button and have repeatability. 

Newer Hemi Rams have a resonator (or a tiny muffler?) after the muffler.  But any performance systems have it between the cat and muffler. 

I'll even let you use your porta-band if you want . It should be here today. Can go in the straight pipe between cat and muffler.   

Drivetrain fluid change last weekend. Transmission fluid and filters looked relatively new. I was hoping it was gross and a change would make it work better .  Other fluids were definitely ready for a changing. 

Put on a giant muffler, the largest one that Dynomax max in fact. It is much quieter but still has that tinny sound. Ordered a resonator, hopefully that helps.

Second power steering pump is making a loud ticking noise like the last one.  Shop is going to put in a Mopar unit.   

how's the shoulder to manifold comfort and noise situation? Satisfactory?
