Hey All
I am considering adding to my partly upgraded exhaust as currently I have raptor H6 headers 3rd cat delete and phat quad tip s/s mufflers
I am looking at 200cel cats and possibly the xforce centre and y pipe but am quite hesitant just to bolt it on as the x force muffler can be quite droney
I have heard from a muffler shop that the stock centre pipe muffler is not overly restricting he also compared it to a forester muffler
I dont have much of an idea on this type of thing and am just looking for some advice
Also with cats do brands matter as with most things for better quality ive heard only jap cats are decent but dont know much about it,
for example....the diameter of the cat and pipe to go from headers to the cats and then from cats into 2 to 1 then to centre pipe
Any advice is appreciated
Cheers
