I heard that putting the muffler on the tail pipe adds about 50 MPG's, so I had to test it:



I now need to go back out and try to find the muffler. I think I might have hit one of the road signs with it on the way down the highway.












































Anybody ever use flex tube from the cat to the muffler? Just curious. My dad says it works great, but I think I might just take the truck to the muffler shop on Friday and just have some regular tube done.

 

Dont use flex tube, biggest POS ever... take it to a shop and have them cut / weld..

Thanks!

 

yes...if you use flex tube you will end up replacing it quite often as it burns out quickly
