my cousin he has an 03 gt with flowmasters im pretty sure 40 series and he asked me how that and a mac o/r h pipe would sound? so how would it.....i never heard a mac so i had nothing to tell him lol
I got the mac o/r h, but it's not on yet, if the husband lets me use the jack to put it on anytime in the near future, I'll let you know. It's been sittin for about a month while I wait...
mustangkid - Mac O/R H + Flowmasters is a deep retro muscle sound. It sounds mean as hell! That was my first exhaust setup, but I ditched it due to emissions and my flows were rusting...
Thats why I have on mine, and I'm very happy with it. It CAN be quiet, like 1500rpm and lower, but get it to 2500rpm and up and thats when it really starts to scream over the catted X I did have on my car. Do you know which 40's he has? Originals or the super 40's? The super 40's I have are supposed to have lower resonance inside, and I must say that the ride is very quiet inside compared to outside.
Basically just tell him its very deep, very loud (not the loudest possible, but loud), and he should like it.
