Headers & Hi Flow Cats question

JLarson

There's nothing in the stock headers to burn out, so your only restriction would be determining whether or not they would flow enough for you. A lot of the guys running Stillen kits are still running stock headers, so I don't see an issue here.

But as Wideglideleon pointed out, HFCs can still end up getting burned out, so maybe your best bet is the LTH's since they eliminate the cat, and if you decide you want/need cats, get them welded in further away where the exhaust gas temperatures have dropped a bit.

That's good to know. Guess I'll end up taking the LTH route. Really don't want to have to deal with cats getting fried then having to spend any more money. Thanks for the info guys.

If you are going to install the LTH's yourself. The right takes about 1 hour to switch out. The left side will take 6 hours, and at some point, you will find God. Your hands will look like you've been playing with razor wire without gloves.

The Japanese have cleverly designed the spaces beside the headers to abrade your hands as you remove them, a blood offering to the Z gods. Based on my experience, it's best to befriend someone who has a lift before taking on that project! Good luck.

I'm lazy and so not trying to go through this, so I this is why I'll be taking it to a shop and have them put it on for me. Won't be looking forward to paying for it, but I do like the ability to point at the car and say fix it if they screw something up.
