To get rid of check engine lights, and to use the full benefits of headers you will need a tune.

I doubt the exhaust would smell bad. Mine only smells like oil due to bad valve seals

I know of many people running this setup with nearly a straightpipe. You should be fine. Hell, start a thread in the engine section about china headers. I'm sure others will chime in

So another of my threads gets hijacked with someone trying to get someone to buy Speed engineering junk:( The copied our headers and Y and didn't do a very good job of it. I've seen so many post from people that have had tons of problem installing their version of our headers. But you can buy them if you want to take the chance.

meet in the middle at $400 and maybe it would be worth it, but $100 price difference is quite a bit

Hey Black2002ws6, I'm looking to buy a set of LPP headers for my truck, but they're out of stock on your website. Can you tell me when you'll have them back in stock? I'll pm you about this as well, the email on your website isn't working. Thanks
