Down to the wire

Changing the exhaust again tomorrow. Okay first off its a 2007 double cab 4.0l v6. My planned set up would be running stock headers, keeping all four cats and replacing my dual flowmaster with a Y-pipe to 4 inch tips. So pretty much just replacing the muffler with a y-pipe for dual strights. Can somebody find me a video or post theres if they have the same set up. No muffler, just all four cats
Thank you

 

I know the open headers one, the guy had it cut at the first set of cats so it had alott of back pressure causing it to sound like trash. I watched one where a guy had no cats no muffler just stright pipes, not true duals though, but having the full pipe gives it a great sound.

 

yea theirs a black DC i believe on youtube that is open headers. Sounds like a sick honda ricer car.

 

Im not talking about open headers guys

 

You said and I quote

"My planned set up would be running stock headers, keeping all four cats and replacing my dual flowmaster with a Y-pipe to 4 inch tips."

and "No muffler, just all four cats"

Sure sounds like open headers to me.

 

Isnt't open headers having your headers then everything is cut out after? No cats, pipe or anything?

 

So cutting the cats and leaving them in doesnt make a differnce?

 

I'm going to leave all four cats in but just cut the muffler out. and place a y pipe where the muffler would be to have duals
