Hey fellas, I recently found a video on youtube that contained a truck like mine that has 3" straight pipe from the y- pipe back and im wanting to this to my truck. Will straight pipe drone the cab and will I hurt anything?

 

Only if you don't add chrome truck nuts at the same time.

 

No truck nuts here lol.... My main concern is drone I do alot of towing, on the performance side will it hurt anything?

 

Yes it will drone, especially if you're towing a tall trailer - sound bounces off solid objects.

And yes it will hurt your towing performance unless you get custom tunes to account for the increased exhaust velocity.

If you really want to dump the muffler and cats, get it done right with a quality system (to include long tube headers) and custom tunes.

 

Im planning on keeping the cats. I don't have alot of money so I can't afford headers and what not. I'm thinking I should just keep it stock.

 

I think you're making the right decision - save that money for a programmer with a custom tow tune.
