I can't see it causing any noticeable power loss and certainly no more than having the honeycomb in place. Especially since both cats had the honeycomb broken free from the sides of the housing and moving freely. I would imagine it does exactly what exhaust is designed to do in a straight-through muffler. Go slow and have the sound waves bounce around and cancel each other out during idle or low flow conditions. Then under high load, it blasts right past. Would be cool to see someone like engine masters do a test but I have a feeling the difference would be minuscule. Dual 3" is kinda overkill for any NA motor even a big stroker boy.
Yeah especially in that case if it was already messed up then you did it a favor. They were talking about removing the material from a good converter so I’m sure you probably helped flow. That looked like it was messed up.

Finally fixed my left rear window. When I got it the passenger rear window didn't work so I fixed that, then shortly after the driver rear quit. For the first time in a year both rear windows work!

Also had to take a picture when I was out tonight.

Dont think I have posted any pictures since I took the running boards off either.

Love this truck. Nice work.

Right there with ya. I was getting ready to pull the trigger on a set of emergency lights and Bilstein 5100's... then our front load LG washer flew apart. The month before that I had planned to buy the Westin Elite XD Pushbar... then my wife notified me that our water softener crapped itself... Oh well. I'll slowly add to it as time and money permit.

Anyone have a favorite style or brand of tow mirror? I had to back my trailer about 250 yards down an alley with cars parked on each side. I felt like Stevie Wonder with the factory mirrors. My current mirrors are power adjust but no lights or defroster and I don't really want to add any complicated wiring.
