4" pipe? WHere does the 4" start? After the muffler? You probably lost some serious torque.

 

how about some underneath pics and sound clip??

 

That is what I was thinking--4" would cause serious torque to disappear. I've had people tell me my 3" pipe probably took a decent amount of torque away from my 4.6, though I can't say I've noticed...

 

no your fine with 3". But that flowmaster on the other hand...........

 

^ haha

 

You can kind of see in one of the pics where it ends underneath from the side. It's about 2 feet long with a 2.5 pipe on the end that bend towards the muffler.

I haven't noticed and power loss. I also dont tow or race the truck. When I do tow something I'll see if I can notice the difference.

I figured I'm running all the cats and stock piping along with a better flowing muffler its just as good as those removing some cats and running high flow mufflers out the back. I could be wrong though.

I'll try and take some underneath pics and sound clips. Just busy lately since I"m still working on the roll bar for the bed.
