Exhuast question

[da1990]

Wats up guys so I'm about to get my exhuast on my integra, I'm getting a 2.25 custom pipe from the cat back, I also want to buy a hi flow cat off eBay.... Now all the cats have a 2. 25 inlet or 2.5 but all the headers I'm looking at have a 2 inch outlet, how do I get the headers connected to the cat If the outlet and inlets are different sizes, will they weld on with no gap? Need some advice thanks guys

here's my advice : Don't buy ebay junk

Well even an invidia test pipe and other name brand ones have a 2.25 inlet on the cat and all the headers are 2 inches? How does that fit?

[thatnikkatito]

Buy a header

All the headers are 2 inches at the end, will that fit fine on the 2.25 inch cat?

Lmfao ur goin about this all wrong keep the header or get the one that is 2" cause when u put the donut gasket it adds the .25 u will be fine no extra nothing needed
