MX performance + avo front pipes
 

Looking for a front pipe and overpipe (2.5in) for my NA RHD 86

Can't go for the Nameless combo as they are designed for the LHD and Perrin is increasingly harder to get in Aus

My two options are:
2.5in Perrin ovepripe + ceramic coated and catted AVO front pipe
or
2.5in MX performance over and front pipe combo

Any thoughts towards which one would be better or does it really not matter that much?

Also, are there are reasons to go 3in when I have a 2.5in catback (Perrin resonated) and am considering FI down the track (hence no rush for header upgrade) or will 2.5in application be enough for healthy gains?
