URD MAF CAL vs Doug Thorley LT

Hey Everybody,


I am interested in getting either the URD MAF cal w/plug n play or the Doug Thorley long tube headers w/ 02 sim. they are about the same price. Questions about the doug thorley headers how hard is it to install the 02 sensor. Also I live in Georgia would emissions fail me if I installed these headers. What performance gains are there. Also if you where me which would you choose. Any answers would be great.

 

any bumps

 

i would go with the long tubes first then the maf calibrater, o2 simulatar and plug and in play, when you order the maf and the o2 chip urd can have both of those chips wired in the plug and play harness that way you can just plug the harness in and not worry about splicing.

 

I'd get the headers which will yield better performance. o2 sim is a simple 6 wire hookup.

If you get the headers plan on changing the muffler out because it will sound bad with the stock setup which causes rasp from removing the front 2 cats.
