So I bought a set of ART pipe V3 however they didn't come with gasket, gasket rings and bolts, can I re-use my old hardware or I should get new ones and where to buy them? I've e-mailed motordyne support and still waiting for them to respond. what do you guys recommend?

also do I need to worry about CEL since these pipes comes with extended o2 bay already
Thx

 

ART pipes do not give CEL, but make sure to disconnect battery prior to installation anyway.

 

I'd get new bolts, if you have a large ACE hardware you should be able to find some good grade 7 fasteners that will work. I would recommend coating the threads w/ copper-based anti seize (and all exhaust bolts that you end up working with down the road).

 

just got a hold from motordyne, they quoted me $60 for the hardware set 10 bolts, 10 nuts, 2 2-1/2" 2HOLE GASKETS, 2 O-ring gaskets.
are there anything still missing? do I still need the triangular gaskets?

 

Why do you ask the same question in all different parts of the forum? You had your question answered already regarding the gaskets. It doesn't seem like you believe us here at the forum with many members including me who own the system.

Listen to Tony at Motordyne regarding the hardware, he will not steer you in the wrong direction.

 

I'm sorry if my action offended you and believe me I do trust you (at least you've done it ) but since this is my first attempt on changing CATS on my car and I'm a lazy person, i would rather do it right at the first time. by the way it was a lady from sale at motordyne who answered my e-mail. Again I'm only trying to do it right.

 

Be sure you soak those stock bolts 24 hrs prior w/ the 50/50 Acetone/ATF mix and hopefully you have all the proper tools. Here's a thread that might help if you haven't seen it.
