any recommendations on what to DO with them?

should i sell them on here, or on ebay?

10,000 miles exactly on them.

 

Get in touch with this guy or place it on the Marketplace section.

I would keep them. You wont be able to sell them for much at all, and to replace them it's insane. (probably $600 each) If your test pipes or HFC's crack then they would be good to have around to hold you off untill you can replace. Not to mention taking them off in most states will void your warranty. Throw them in the garage.

 

Hold on the them. Maryland cars must be inspected before sale. It will not pass with test pipes.

 

thanks for the help! im going to try to get in contact with that guy in NC.

i have high flow cats on now, not test pipes.

 

like everyone said above, you can't much for them. and in case you need to replace them, they will cost alot to replace. not worth it to sell IMO.

 

+1. Never know if you're going to need them. Also aren't going to get too much for them.

 

Keep them. Even with HFCs. You never know if they are going to break or crack.

Plus you aren't going to get anything for them.
