well i finally got some pipes running after my precats. i was pretty tired with the drone and my *** vibrating 24/7. but anywho.

left my truck at the shop. drove it away. then finally looked at what they did.

is it good or bad to run 2 pipes running of both cats?. its sorta what i wanted? but idkk heres some pics. and i am finally adding pics of my truck in my album there not very good though lol

 

umm..

so you have true duals...with only precats, and turn downs..

which mufflers do you have? no matter what you do that setup will drone and "vibrate your ***"

 

What are you trying to ask? If its ok to only be running two cats? Well duh! 4 cats is way too much, two cats will be fine, especially our 2004 pre-cats. They handle the fumes well, with only a mild cat-less scent.

 

You have a pipe running from each precat, turned down, with no crossover?

I'd have an H pipe welded in for better performance, or an X to quiet the exhaust down even more...
