Default headers beating floor pan. need advice

dont know wat type of headers they are but i only paid $100 for them and they are already coated so please dont tell me how shitty they probly are, i already know this.

they hit the floor pan which i understand is normal but its very annoying, is there anything to put between the floor pan and headers to dampen the clunking sound it makes?

I don't think it's normal, I think your motormounts are fucked. They shouldn't move at all

Don't put anything to stop the banging. It will crack the header in time. I suggest a set of Prothane poly mount inserts. They are about $60 for the pair. Stock motor mounts are a very common failure item.

As mentioned, Polys will solve your problem. There are a few half-*** remedies out there you can try, but taking care of this problem the right way will be to upgrade your Motor Mounts. You'll spend $60 and a weekend cussing, but once you're finished, you'll be glad you did it.

Good luck.

I thought I was a genious by putting a rubber spacer b/w the Y Pipe and the floor board. Solved the problem, but now I have a crease in a brand new ORY. Put a nice big bend in it.

Do yourself a favor and get prothane engine AND transmission mounts, NOT polyurethane.

+1000 for motor mounts.

whatever else you attempt is only going to make your y-pipe/headers act as motor mount and eventually cause problems that can't be resolved with another cheap fix.

prothane mounts are polyurethane.

ok so obviously ill be replacing the motor mounts lol. and BTW its the collectors that is hitting and the motor is not rocking anymore than normal but ill change them anyway just to eliminate that problem.

will the poly mounts make a vibration like solid mounts or do they absorb some of the vibration? its no big deal but id like to know wats gonna happen.

thanks guys

poly is going to vibrate more than the stock rubber mounts (not as bad as solid mounts) but it's a good trade off to not have that annoying clucking anymore.

poly mounts aren't as bad as i thought they were going to be. i don't feel too much of the vibration, but i can feel the cam. not a bad thing though.

If you go poly mounts, you'll know why your motor is bucking like a mule once you get the rubber ones off. I put headers and did a motor mount swap last weekend, and almost decided to skip motor mounts because of how hard I heard it was.
After deciding to go ahead and do the swap, I'm glad I did. The rubber mounts were toast. There is a little bit more vibration, but it's way less annoying than I would imagine banging headers to be.

Poly mounts for sure, i did just the drivers side on my car and put a new stock mount in the tranny and torque arm.. solved my header banging problem that i had as well.. I will do the passenger side mount another time.. they are quite the pain in the *** to install.. But was worth it for sure... As a matter of fact evrything ive done to this car has been a pain in the ***!! lol.. not one of your easier cars to work on...
