ok so i finished my exhaust set up to my liking..stillen y pipe and topspeed pro 1 exhaust
im now looking to buy megan long tube headers but i have a few questions if anyone can answer...1 will these headers work with my new exhaust set up ? 2 do long tube headers replace your stock cats or is it a direct bolt on to the stock cats? 3 if the headers replace my stock cats will i have an issue with the check engine light? srry just new to this so i want to make sure im doing the correct mods

 

1. yes.
2. replace your stock cats.
3. no. as long as your o2 sensors still work/don't break them.

 

so the 02 sensor plugs in to the long tube header?

 

Yes. Megan, I think, provides the non-foulers to keep the CEL off. You should check to see if they're included or not.

 

would long tube headers be worth it or just buy hfcs? ive heard the cost to install headers is expensive and the power gains arent worth it i want the car to breath better get sum gains and sound like a beast

 

Headers are a terrible investment - again for the reasons you just said. I'm not a fan of HFC, or really anything other than ART Pipes - so I'd invest in those instead. If you can't spend $600 on them, find some FI HFCs for $300ish new.

 

long tube headers doesn't do much v6's, if you had a 6L v8, then thats a completely different story. Your best bang for your buck would be HFC's, tune, spacer, then exhaust.

 

fi meaning fast intentions right? are kinetix hfc good? the price seems to b good on them

 

is any1 running long tube headers out there? installation cost?

 

Have you looked in the exhaust subforum?

If you have to pay to have them installed its going to hurt. If you can do it yourself not so bad. Kinetix is good quality for the price, I've seen several sets of them and they have all lasted and performed just as well as the other brands. Even had one guy who payed out the a$$ for fast intentions HFC and then had them fail on him 5000 miles later.

Keep in mind that you're going to need a tune for sure if you put on headers, you'll actually lose power without it. If you're not sure either way I'd say get the tune instead of the headers, it'll make a much bigger difference than just bolting on more parts and hoping for the best.

 

LTH have an advantage when using other mods such as: performance camshafts, forced induction and high flow intakes.

If you don't have performance camshafts as a minimum than headers (LTH or shorty's) are a waste of money on VQ's.

 

If I ever go back to NA I'll Be doing the LTH/ cam route. Sounds so mean

 

Long tube headers are better then the common shorty's when it comes to performance. Once you open up the rest of the exhaust and intake, you should see decent gains once tuned. And plus 1 on adding cams to the mix.
