ill definitely check that stuff out; also, I've been looking online, and I can't find a flex pipe anywhere. Is it part of the headers, or a separate part, or what? Where can i buy one?

I thought I answered this in my original post. Road Race Engineering sells flex pipes and an exhaust shop will cut the old one out and weld in a new one...

IMO, that flexpipe looks F'd.

When it comes to exhaust problems, a muffler shop is cheap and effective at fixing it. Here's how I suggest you find a good muffler shop: Go to an auto/performance shop that has nothing to do with welding exhausts and ask them where they have their exhaust work done.

a flex pipe can cost about $60-100 alone. I got mine for $55 and I knew the guy.

thx man, this stuff worked really well, i patched up the leak, there is no smoke anymore, and the engine sounds a WHOLE lot better
but there is still noise coming from what seems like the valves. I'm thinking maybe my exhaust valves wore out because the leak was there for a long time. How can i check if my exhaust valves are okay?

New Flex Pipe

I am about to purchase a new flex pipe for a similar reason. The weld just before the mesh area completely broke twice ( I had it rewelded once). Mostly my fault. I am able to get a new piece of pipe and necessary gaskets for about $140 (Bosal). The dealer wants $280.

Removing it may be a challenge though since exhaust bolts have a greater tendancy to seize up. I purchased some anti-seize aerosal foaming stuff from the dealer just in case. I can't wait to see how it works.

Good Luck!
