Thread: 2000 grand prix slp headers

Flexpipies are flex pipes, just make sure you get a double walled or tripled walled and you'll be fine. The one Scotty linked will work fine and is inexpensive.

They have triple wall? Are they stiffer any disadvantages?

ive not seen a triple wall, double wall is fine. the new one is much stiffer then the old single wall i replaced.

ScottyDoggs is it possible to cut the old flex off my headers and keep the overall length the same with this flex you linked? Or would you think I would have to get a flex with 2" of pipe welded on each end to make it easer for the guy welding it?

whats there is about 6 inches. so it should be a direct swap. if you gain clearance its a plus. i know i did. id not add any pipe to it.

only thing id think about is a v band on both sides of the flex. that way you dont even have to un bolt the dp if the flex fails down the road. you just cut the two v bands off and re weld them on the new flex.

So your saying if it ends up being up to like what a inch shorter or so it'll still fit fine? How much shorter did yours end up being? I'm not to concerned about the new one going bad I don't drive the car alot it's a summer car because it's been painted and I have ALOT of money in it. Everything is literally new lol I drive it like 6 months out of the year I only put a 1,000 miles on it last summer.

its fine a bit shorter, things still line up fine.

i keep forgetting to take a pic of how it sits now.

Okay thanks man
