I'm thinking of getting a HPI Dual/Split front pipe and either a Trust PE II or APEXi N1 Evolution for my R34 GTT.
Seeing as the catback exhausts are 80mm (or 80-95mm for APEXi) is it recommended for me to get a 3" cat?
Or does the size of the piping not matter in this regard?
There are so many brands out there, SARD, APEXi, Catco, X-Force, MetalCat.
The jap ones are tooo pricey for a cat so i'm looking @ the last three.
I'm looking to get a 200cell cat with maximum CFM.
Are there any issues with the cats mentioned or anything i need to know?
Any recomendations?
ps. I have tried a search
Thanks
