eBay Shorty headers

Can anyone with real world experience chime in on these? $100

I could be wrong, but it looks like the collectors are cast iron. Two different type of metals might not last too long if they are.

with almost no significant power gain from shorty headers, Id just do long tubes. The same effort and a lot more results

There is gain when hooked up to high flow cats. Longtubes hold the power right through the power band. Shorties drop off up top.

And you know that welded connection is in no way smooth. Would be a very rough fit inside.

Never heard of the brand. Do long tubes if you can. Long tubes realistically will get you 25 hp, a tune another 12-15 . I and several other friends and people on here have gotten 17-20 hp with shorties and hiflow cats and another 12 with tune. My hiflows made 15-16 hp, the shorties were only good for 4-5, same with the other folks. Numbers on a dynopak dyno and on JDP ‘s dyno and dune as a power test to see what hiflow cats really did power wise.

My car made almost the same power with shorties and hi flows vs longtubes with cats. 374 rwhp vs 375 rwhp. Both had torque just shy of 400 ft lbs at the wheels. The long tubes hold power right through 6400 rpm where the shorties start dropping off around 5200 rpm. I think the longtubes provide better power at the track because of this. I will see what my times are as soon as I get back to the track....numbers don't lie.

My total hp with shorties, hiflows and tune was 32, Lt’s and tune seem to be around 37-40. This jba for my setup. Friend with same as me switched to LT’s, didn’t notice the extra 5 hp but sure noticed the extra bottom end tq lt’s Give.
On power I noticed opposite. We tested the hiflows, they peaked at 15 at 5650 and fell of to only a 4 hp gain at 6300. The shorties made 5 at 5600, but 12 at 6300. Made sense as shorties known for higher rpm gains, lt’s great everywhere as they scavenge way better.

I think they are just a rough, as-cast stainless piece. Like the flange that bolts to the motor. Probably to help keep the cost down over a nice finished stainless piece all the way through. I could sure be wrong though too...but I would think that wouldn't go over well. They'd be rusting by the time they got to people.


I ordered clamps from blackhorse to use with my SE header setup and they have been working fine. Much better than what came with my headers.

I had the Jba shorties with Solo high flow cats. Im trying to get back to the track and compare my numbers from last year to this year. That's really what tells me the story. I believe the long tubes are actually better up top then shorties. I thought shorties had good down low grunt with the longtubes pulling much harder higher up top. The longtubes sure made the car alot louder with the Corsa then the shorties did.

Wrong there old buddy Ron. Longer tubes make tq lower. Shorter tubes make tq higher.

I thought shortys are better low to mid range while long tubes make power in the higher rpm range.

Seems to be opposite. Shorties wouldn’t be to noticeable by themselves, 5 hp and about same in tq. Hiflows real make the combo useful. As I mentioned, a friend with my same setup didn’t notice any more top end going from shorty/hiflows to lt’s, but the bottom end was definitely better.
But what was interesting was that With a stage three cam, I thought the Lt’s would’ve been more noticeable on the top end in his car. Interesting.

My 4 years with shorties and hi flows was ok. But talking with other members and tuners I was expecting the long tubes to be an improvement at the top end of the curve giving me more mph at the track. My dyno sheet showed the shorties falling off up top while the long tubes made power throughout the curve. That's my understanding anyway. I just can't find the damn sheet to post it.
