Daytona IROC Stock piping size

[GLHSKEN]

Downpipe is 2.5", What size is the pipe from the cat back. Almost looked 2-2 1/4"....

[BadAssPerformance]

2-1/4 sounds right... maybe smaller over the axle? :eek:

[GLHSKEN]

LOL... No issues over the axle... Who needs that...

If it's the same as 8v applications-
2.5'' before cat
2.25'' out of the cat
1 7/8'' right after the last 90* turn to go up over the axle and into the muffler
