L67 Headers

**abrahamhuerta95** · 11-30-2014

Simply put... What are the best headers money can buy? For a highly modded gtp pushing at least 350-400whp. Top three brands?

**Sven the Sexman** · 11-30-2014

SSAC, SLP, ZZP...WBS...they all work...some need modifying, some will work as is.

**sseilmnop** · 11-30-2014

ZZP are probable the best quality at the highest price

**BrandonHall10** · 11-30-2014

Slightly off topic...

Are there any performance gains from the high dollar headers vs the cheapo's?

**Scottydoggs** · 11-30-2014

probably not much really.

**sseilmnop** · 11-30-2014

Speed daddy don't line up with the ports.

**Frosty** · 11-30-2014

Highly doubtful. Maybe a couple. Not enough to justify an extra 400$

**16MustangVet** · 11-30-2014

togs ftw!! gots 2 sets.

**GTPpower** · 12-01-2014

TOGS. /thread

**Bio248** · 12-01-2014

TOGs suck.

do yourself a favor and scavenge the internet and get some S&S headers. they're no longer produced so you'll have to find a used set.

**abrahamhuerta95** · 12-01-2014

Most of these I'm having trouble finding, except the zzp ones.

**GTPpower** · 12-01-2014

S&S are pretty small, if you're looking to make big power. Great quality though.

Here is Speed Daddy's Ebay store ... The listing is specific for the L67

Speed daddy are least expensive. You may or may not have trouble bolting them together. The flex is considered weak and you have to buy your own clamps and gaskets.

They are cheap! Chinese made.

for 95% of the "builds" out there, they'd do just fine.

i'd run them on an all out blower car and sacrifice a little top end power to have a set of headers the fit appropriately...

**blueguy** · 12-01-2014

Pfft, my $200 speed daddy's fit just fine after I had the flex cut out.

I could never bring myself to spend anything more than $250 on a set for a car that costs maybe four times that in perfect condition.

I loved my pacesetters with the huge primaries...but they had to be completely welded up before they worked worth a crap. Collector kept blowing apart all day long.

When talking big HP and a lot of flow, keep in mind not all headers are the same size. Big Dog TOGS were the way to go for flow.

Had pacesetters a while back, never again, what a nightmare. Any time you guys think parts are expensive for these cars, just pretend you have a G8 GT and try to order, pretty much anything. Whole different ballgame in the LS world, i'd rather leave my G8 stock and mod the GP all day. If I were to get GP headers today, it'd probably be zzp's, but I think a plog/ported rear will be enough for my current goal.
