Have searched, people are saying X force are good and bad, Metal cat are good and bad, steel internals are bad cause they melt or buckle, ceramic internals are no good.
Im confused, I want to fit a 3.5 inch hi flow cat but dont want to spend a ridiculous ammont of cash on it. Ive got HKS exhaust front and rear sections with Nissan or compliance cat bolted in at the moment.
Which hi flow cat do I get, needs to be able to handle 300AWKw.
help!!
