    After putting a few hundred $$ into my front end, I'm looking to do an inexpensive fix and lift my sagging exhaust tips. I've seen the post about using an adjustable clamp to tighten then up, bit would rather spend a few more $$ and replace the older failing part. I'd look under the car myself but its sitting on 3" of snow. How many of the insulators do I need? And a part # would be great too! Thanks!!

    Right, I think the part description calls it an exhaust insulator.

    Should be like 7 of them.

    2 that hold the middle up where the Cat converter is. 1 where it bend around the gas tank to the Y, then the mufflers each have 2 that hold them up.

    Ok, I replaced the 4 hangers in the back end of the muffler. It lifted the tips a little, and my left side is still a little low. I don't think you want these too tight into the bumper or they'll start melting it. Definite improvement but i think it could be a little better. Sorry about the crappy cell phone pics.

    Thanks! I'm just wondering where they should sit.....like they did when new. I have to look at the brackets to see how they can be bent to lift that left tip just a bit.

    I just looked at old pics of my 00 GT and the left tip on it sat slightly lower too.

    I just did the 4 in the back, but will probably add the rest to my next order from Pace (I want to get the front and rear strut tower braces too). They are pretty easy to replace and i did notice the ones further up the exhaust were stretched out.

    I replaced all of mine as my exhaust was sagging and bagging around on the sway bar. I did do the hose clamp mod to level out my tips.
