ok I finally got this done on the FG ute this morning. 160 bucks and this place didnt hesitate at all doing it so I assumed they have done it before. Thoughts: centre muffler is massive and pretty heavy, no wonder its so quiet. The sound on start up is perfect, doesnt drone at any speed, not too loud at all. I was exspecting it too be even louder than it is, even though mine stock was very very quiet compared to other stock T's. I think these should be this loud at stock. cheers
