Default Header - Exhaust Options

Well, think I have an exhaust manifold issue on my 2003, or I've picked up a moped running in my engine.

Basically have a drivers side puttering sound like a moped. No performance issues, just sound. I suspect it the exhaust manifold, either bolt of gasket though its very very hard to tell with the heavy rust. Thinking if I am going to invest in any effort with this might as well explore options.

Any opinions on Header, Exhaust options for 03. Seems like OBX has a reasonably priced header, exhaust kit. Any have one of these?

As always any thoughts most welcome.

Sounds like you have the infamous broken header bolts. Do a search here and you will see many others including me that have had this problem. Replace them all with the GM upgraded ones that won't rust and snap.

This was posted on another forum, we've been talking about that kit for a day or so. Just an option.

Been looking at that same kit but with cats.

Kinda wondered if the site is legit. Hesitant after being burned on a seat I guess.

Be careful. Both those links posted are for 2007+ H2's
You need to call AA to order the correct Kit/Headers

yes the link I posted is but if you just enter your information it will pull what you need exactly-the pic is the same though for either kit.
