'07 4.0, best exhaust for towing

'07 DC prerunner
I'd like to find the best exhaust possible for towing my ski.
Long tubes or shorties?
Remove all 4 cats or keep 2 or all?

Long tubes / catless y-pipe / cat back....does anyone sell the whole setup?

 

What do you mean by "best"?? Performance?? Not getting soot on your ski??

You can look around URD and talk to Gadget-You'll be able to get all the parts there depending on what you want.

 

Performance and mileage when i'm not towing.

I did check out URD after I posted
They had...
Catbacks:
AFE, URD, JBA, Jardine
Y-pipes:
DT, URD
LT headers:
DT

Only one maker of LT's for our trucks after 4 years.
I'll do like you posted and talk to Gadget at URD for the best setup.

 

If you want the best performance for towing, get a muffler that sounds good, and keep the OEM setup.

Any aftermarket exhaust setup you go with you will move your powerband up a bit in the rpm range (trade low end for mid/top end).

Best performance mod for towing... TRD Supercharger.

 

Yup....Xrunnit hit the head.
