Will it void factory warranty if I put a bassani x-pipe with 3" borla pipes?

 

chk w/ you dealer. I had 3.73 FFRP put in w/ a warranty by Ford for 12,000/1 year. Make sure you get it in writing.

 

I am not sure if you have to cut your catback to get it off on the IRS stangs? If you don't, just swap it back off if you need any warrenty work

 

it'll only void certain parts on your warranty. if they can link that X to a failed part, they'll void it. if your tranny goes, they can't link that damage to an X pipe. trust me, pretty soon you'll just say fudge the warranty and throw a blower or nitrous on there.
