Mak y pipe
Has anyone had or currently have a rattle almost loose baffle or heat shield sounds from their mak y pipe with stock exhaust?
Heres what I have 2013 F150 5.0 S&B CAI,ported mustang intake, mak off-road y pipe and stock cat back. As soon as I installed it I heard a nasty (horrible) rattle at 2,000 rpm. Obviasly checking for any rubbing or anything loose and finding nothing. After about two days of driving this I bought a MBRP cat back with a resonator hoping this would quote it down. I was wrong, while the rattle was gone it sounded like glass packs. So at a loss I sold it to a guy I work with for a little less than I paid plus his stock cat back that has 30k miles on it. I literally had the MBRP on it for 5 min. I'm thinking my stock cat back at 100k has a loose baffle or something. Wrong again 30k mile cat back sounds even worse. I have a buddy with the same mods only difference is he has AFE y pipe and only has a hint of rattle at wide open throttle. I really don't want to spend twice the money on the AFE but I can't deal with the horrible sound it makes. Thanks |
