Also try to make sure the 2.5 to 2.25 step down is smooth.

yeah that's what i would do.

But if your header is 2.25 collect, just get a high flow 2.25 Cat to suit the entire system and that should be sweet.

went to right price exhaust today, they quoted me the metal cat with $310 fully installed.....but i dont know they talking about the branding 'metalcat' or just a metal made car. (Is a genuine branding 'metalcat' like that cheap?)

and then i went to Lee's exhaust, they quoted me $290 for a magnaflow cat with fully install......

so which one should i go and have they quoted me the reasonable price?

anyone? :)

Clarify re: the metal cat first with right price...

but i found the 'metal cat' even on ebay is $300++ for the cat itself, how come they can do $310 with fitted....
