Nameless Performance Equal Length Stepped Header

[Deathreaper]

Loving these results, forgot to ask - do these come with all the gaskets required?

probably needs a touch more exhaust cam retard there at 3200.. hard to say till i get on the dyno with mine. It is possible that is it just the one are that they could not get the nth order resonances to line up in a way that would boost output in that range. I know lots of folks still want to believe the factory torque dip is 100% tuning or the cat but it isn't, it's the design of the factory header.

Also note, these resutls are with the rest of the exhaust stock

Exactly.......hitting over 200 on 93 shouldn't be an issue with a full exhaust.

Looks really good for a daily or short autoX courses like I have....

Wanting to see the 2.5inch exhaust results...

The bit i circled in green is the part that impresses me... that is the toughest place to find gains on the dyno for me. Unfortunately, it looks like the best gains there were on the Motec, not the stock ecu but at least it collects data that we can use to figure out what we need to do on the stock ecu to get those same gains there.... could be injection timing, knock sensor sensitivity, some unknown limiters etc.

I hope, and expect, that we are seeing muted gains up top due to the remainder of the exhaust being stock. I'm sure 3" header back will own the dyno sheet crown but I really want to see with it does with 2.5 catted nameless over / front and 2.5" catback (I do think the stock midpipe becomes a restriction once you do the header).

It's doable on 91 with a proper tune with just headers and a fp/op, so it's definitely doable on 93 with a full exhaust.

If I weren't going supercharged I'd see what kind of gains this would put out when the rest of my 3" exhaust gets here. Don't want to buy a separate tune though just for results I don't care about. I think @Shneegle is getting a full 3" though with this header. Hopefully once his arrives he can post some before and after numbers. I think he is staying NA for a while.

Now the header is out (Congrats the charts look great!)... when the project was started you mentioned the goal of power but barely louder than stock package of header + exhaust (can't remember if it was on the forum, facebook or your webpage).
Everything I have read or heard of the nameless other exhaust components say they are very loud. So is a new stealth quiet headerback exhaust being designed as well to pair up with the headers?

I second this notion. Depending on price would purchase.

150 lb-ft in a damn near flat line for 4000 rpm range.

This is spectacular. A driver's setup. Great job guys!

What SC are you coupling this header with? Interested in respect to clearances overall. Thx
