I need some good tips, probley gonna be stuck of the ends of a flowmaster 40 series, i was looking off ebay, should they be 3" wide? and how long should they be?
16,18,22,24?

 

oh ya and with a stock set up, how thick does the inlet need to be?

 

Mine are 18" long. You can't see where they start from outside the car.

 

Got some pics of mine in car domain site as well -- 18" or 24" as well I believe, chrome - not stainless. They are slant cut, 3" -- do not go bigger than 3". I prefer them over MOST tips out there, but there are some I like better. You could go stainless, but mine have been rust free for 3 years (spray them down w/ WD-40 after cleaning them, and dont wipe the WD-40 off) - plus if they get scraped up a little, you dont care as much since you didn't pay stainless price.

 

My tips are chrome. I've had them on the car over 4 years and they're still in great shape, mainly because I take care of them.
