So I got rid of my black DT and bought a moonstone hdi, just wondering whats best for a stage 1 map.
Decat standard centre pipe and straight pipe at rear
Decat. De centrebox and a nice back box
Or just full straight through?
Just looking for something that sounds decent and will compliment a stage 1 map well
Cheers

2.25-2.5" bore, no cat, no mid box and a straight through back box of whatever size you want depending on the noise your looking for.

2.25 is standard, yeah. You'll probably find your current one is a pattern part though, usually around the 2" mark, maybe a little bigger.

Yeah standard is 2.25" but tends to be a little less at certain points unless you have a pattern system where the ID in places could be well under 2"
Even 2.25" with proper mandrel bends would see gains.
