I need some help...

First of all can you use like a WB header on a HMF pipe?

Second...do you guys think it would be worth it to buy a WB header and E-series exhaust if it is a year old, but looks like it is in condition? Basically I'm thinking about buying this used one or getting a brand new FMF powercore pipe because I wanna spend under $300...

How much do you think a used WB pipe and header would go for?

HELP PLEASE!!

 

you can get a used one but I would take out the packing inside the pipe and repack it once I got it...you can buy the slip on for now and get a head pipe later on when you get more money if that is an issue...one more thing you left out is you will need to rejet the quad(very important thing to remember). Any ?'s just let me know.
