Do I need headers

[Jstang23]

I've heard you can melt your stock cats and grenade your engine with boost. IDK if that is true so maybe someone can chime in, but I've heard that multiple times.

Yes under boost it is common for people to blow their stock cats. Even with superchargers such as Roush with factory warranties its been known to happen. But that being said other people never have problems with them, it all comes down to how you drive it

But my 2 cents on headers is unless you want them purely for sound or chasing the last 5-10 hp on the top end they aren't worth it. The stock headers are already shorties and actually flow quite nicely!

The only reason I would get headers is for peace of mind knowing I won't grenade my engine in the off chance the cats fail while I'm WOT

worth it is subjective. headers let you make more power with less boost. and they give the added bonus of more sound.

worth it is always subjective, no different than if you should add a blower, for some its worth the money, for some its not.

sound good and flow good though

Headers on a boosted coyote are definitely worth more than 5-10 HP. The more boost and timing, the more beneficial the extra flow will be. It also makes changing out the cats super easy, to either no cats or better cats later. Can't do that on the OEM manifolds.

I just did headers on my car last week, on jackstands, and yeah it is a muthafuggin bitch. (the passenger side anyway) If you don't have a fairly extensive set of tools, and are a glutton for punishment, I'd say skip this. If you have a lift to use, that totally changes things.

Headers with boost are a totally worth it. Anything toy can do to increase flow is a plus. stock Cats are fine NA but once you go boosted they are going to fail and they are a restriction point also. If you cry about the cost of install well that's on you for not doing it yourself. Yes the passenger side is a pain in the ass to install but MAN up and get it done or PAY up and have it done. LOL
I had never done a set on an S550 before and the first set I did took about 6hrs.

I agree. Just don't make the mistake of getting a set of LTH headers like I did that didnt fit for $hit. I went Kooks and fitment is perfect.

To run corn boosted nearly every tuner requires a full return system.

100% Correct. Go ahead and go down that rabbit hole like I did.

 

[engineermike]

"nearly" every tuner. It can be done without.

 

[None2Slow]

I dont know what everybodys complaining about. My brother in law and I did mine in a weekend on the ground with jack-stands. There are some tight spots but nothing to bad. I do have a pretty good set of tools and an engine support used for holding an engine while doing the motormounts. It sounds way better. The stock arent that bad and are a Tri-Y design. I went with the 2M headers and high flow cats. They also came with catless pipes as well and now that my county just did away with emmision testing, I may install those now. Heres a picture of the stock vs 2M pipes.

Ahh. Gotcha. I wasn't thinking boosted.

 

[SpeedLu]

I would have never gotten headers with this setup, but it only took 3 months for me to burn out the stock cats. Rather than risk it happening again I just went ahead and ordered headers. It's loud as shit now, but

I gained 20 hp on my N/A gen 2 coyote with long tube headers. And the rumor that you only gain on the top end is a flat out lie. A properly designed set of long tubes will gain power everywhere in the power band from idle all the way to the top end.

You wont gain 50+ hp on a N/A setup, but around 20 is the norm. Like Terry at Beefcake said, LTH's allow you to make more power with less boost and that is a good thing, less stress on the engine and all that. If you're chasing a #, then you need to do whatever you can to maximize efficiency so you make that # at the lowest boost # possible. In other words, build your setup as if you were staying N/A and get the most out of your setup first then throw the boost at it. The more efficient you are N/A and the more power you make, the more you will make once you go boosted.

Ehhhh, gain power everywhere... more than likely not. It is very rare to simply replace one part and gain power everywhere. Not saying it's impossible, you just have a really good tuner or other parts installed on your engine. My statement was referring to replacing just the headers and nothing else. Typically on a stock N/A coyote when you move to LT headers you see a gain of 10 peak hp. You might see 15 gained somewhere in the middle of the power band, but you will also see a loss in low end torque.

When I replaced the pulley on my vortech I saw power across the curve.

headers don't make a lot of sense on these cars IMO unless you're scraping the bottom of the barrel for more hp. you'll spend a lot of money, incur risk of stuff breaking or just coming undone (cause you're messing with stuff), and they will be a lot louder. like, in the engine bay not just out of the exhaust.

people don't think about that kind of stuff. you're trading a lot for a little and the stock manifolds are pretty dang good to begin with. this isn't 1998 where the log manifolds are absolute trash.
