has anyone with a 2012 wrangler used zone's exhaust extensions instead of teraflex's exhaust spacers? they look the same but i want to know about the quality and i cant seem to find what they are made out of. they're 20 bucks less and i plan on doing a full custom exhaust down the road but that could be a year from now. so i just need these to hold me over but i don't want leaks or rattles. thanks for any input!

 

I used them on my 2012 unlimited and the seem to be really good quaility. I would buy them again. No problems so far.

 

Thanks. Just ordered them last night!
