ok.. thanks for the info on the flowmasters..mbut are there any good mufflers for true dualss made by flowmaster... il change if i hae to but i really dont kno what to do... now u guys say keep the cats as close to the headers as possible... so can i just bolt them to the headers or do i have to have some sort of pip in between.. is it possible... thanks... oh do they make dynatech headers and cat combo fo rthe 4.6 97-03 i saw they had them on troyter but only for the 04 and up but for the 5.4... built54 did ur headers come with the cats.. thanks

 

you can PM as soon as you hit 100 posts, and you are PMing someone that has 100 posts or more

 

i used to be able to.. im pretty sure but i was logged off for so long and thought that was the prob.. oh well.. thanks

 

they may have changed the rules since then, but thats my understanding is you have to be a "senior member" = 100 posts -and- 3 months

 

well that answers my question on how i would be able to PM in the future.. thanks

 

i bought the header and cat/midpipe kit, but not at the same time, they only make them for the 5.4... I didnt realize you had the 4.6

 

this is so aggrivating... im thinking about staying with the single in dual out but swap to the 40 series delta flow bc i dont kno what to do for true duals or how to fit it but i still dont kno what i need or what will fit... i need to find a good exahust mechanic and ask him bc i dont kno how much piping i need and everything else.. i really want to get his done... uhhhhgggg

 

i wouldnt go with flowmaster... Its not that big of a deal, if you are doing it your self, just buy 2 pieces of 5' pipe and cut the factory Y pipe... Or just take it to a shop and tell them what you want.

 

do u think i can swap out my flowmaster muffler for a magnaflow di/do muffler... not sure if they will line up or not.. then i wanna get the magnaflow hi flow cats and x pipe... can i bolt the cats to the header since people are sayin keep it as close to the headers as possible or is that not possible.. how much distance.. thanks.. i hope to figure this out by the end of next week.. i guess its more the lining up and fitment rather than parts.. thanks.. u dont kno how much u guys helped me

 

Take some measurements of your current muffler and go to the magnaflow website and look at their mufflers. They give measurements of their mufflers on their website, even for the piping inlets and outlets.
