Ok so I know what I want:
Take out the cats and add high flows(what brand not sure yet)
Get LT headers (brand is still also in question)
Then I want to get true duals (borla mufflers)

Now to my questions, the high flows I think Ill go magnaflow, but the LT headers what is a good brand thats mid range? For the true duals whats the difference between X Y and H pipes? And finally I am not sure which muffler from borla is the same as the roush offroad, I cant find anything on their website??

Thanks for all the help

 

Go with Magnaflow cats, and Dynatech headers. $700 will buy you the headers, or $1200 will buy you the headers with Magnaflow cats already attached so all you will need to do is drop the 1st O2 sensors and bolt up.

Y pipe = single exhaust
H pipe = cheap way to cross over for dual pipes for better exhaust scavenging
X pipe = best method of cross over for dual pipes. Both pipes combine 100% and flow out helping to retain great scavenging for optimum low end torque performance.

You will never get the exact Roush Off-Road Borla muffler unless you score one on ebay or buy the kit, but I have heard the S type is close to the Roush sound.

 

what do you mean drop the first o2 sensor?

 

The front sensors end shoertly after the manifold, pretty much in the top side of the downpipes, LTs go all the way down and end at the cats, so O2 extensions are necessary.
