Exhaust pipes for 1985 Thunderbird
June 2, 2007 5:06 PM Subscribe
When buying exhaust flex pipes like these, to fit over an H-pipe with a diameter of 2.5", would you buy the flex pipes with the 2.5" outlet diameter or do you need something bigger?
My brother ended up having to cut the H-pipe with a Sawzall to remove the stock headers on his '85 Thunderbird. Now he's having problems installing the new ones. He doesn't want to buy a new H-pipe (even though 2 of the flex pipes he wants instead would cost just as much, but whatever), but we're not sure which diameter flex pipe to order. I say he should order the diameter that matches the diameter of the existing h-pipe, but he wants to order the 3" pipes figuring he'll be able to clamp them or something. Help me help him not waste any more of his money.
