[sy2478]

what size is the down pipe to where they merge and from the cat back...it all looks like 2.5"...but not sure...are there any header options for us..? Or should I just port the factory ones.

Re: size of factory pipes

I know your new here so im going to have to say look at the SyTy vendors. There are header options out there but unless your doing a big build on the motor and a Very large turbo there is no need for them. As far as the Down Pipe goes, Yes its 2.5 look around a bit and you can find all the options out there.

Re: size of factory pipes

Money better spent would be on a complete upgrade turbo kit w/dp . Then larger injectors and the list goes on . The stock cast manifolds have been on a few 10-11 sec trucks and arent really *needed* until a certain point .
