ZZP header and mid pipe for the 1.8

[Ltz_driver]

I'm debating on whether or not I should get the zzp header or the bad news racing header. Which one is better for hp?? Anyone wanna help me decide?

BNR will bolt right on and the mid pipe is the same diameter the whole length. The other one has a mid pipe that chokes down at a flange.

I can vouch for the quality of the BNR header, but can't say much about the other one.

 

[$ub$onic]

I also prefer the quality of the BNR header. It is top notch.

BNR that I had ceramic coated.

Jerry (BNR) showed me both options of the 1.8 header in Orlando and he has a quality product. I still seek him out when looking for parts even though he isn't in the WRX/STi market.

 

[Ltz_driver]

Dang that ceramic coat looks awesome dude!! Do you guys know how thick the piping is for the bnr header??

 

[mitdr774]

I do not recall the thickness of the tubing used to make the header and mid pipe. I am not sure exactly how many miles I have on mine, but it is a decent amount. No issues so far.

As far as horsepower goes, they are probably very similar if not the same. When you increase the exhaust diameter, you essentially move the powerband up slightly, and you will likely decrease the torque slightly. So either way, you could feel a bit of a loss in the bottom end, which may give the sensation of having substantially more horsepower at the top end. Go with whichever one fits into your budget. If your budget doesn't matter, buy the more expensive one lol. Your header will only flow as well as the smallest pipe in your exhaust system, so a choke down on the end of the zzp header may not hinder your performance. Don't forget, your exhaust will only flow as well as your intake will allow it to also. Either way, have fun... both headers sound incredibly horrible for my likings, so I'll be keeping that stock

The choke point is in the mid pipe. If you want to run a 2.5" system after the header having a choke point 3' past the collector is not ideal.

With what I have done to my car and based on data logging with HPT I have picked up about 20ft-lbs of torque at the crank. WHen I was completely stock the data logs were coming in fairly close to the factory claimed numbers. Obviously a data log is not the same as an actual dyno run.

At the same time data log numbers show about a 22hp gain.

Yes, the power band peaks higher up. However I do not have issues with power delivery at all.

I do not know what your liking is, but with the exception of extra noise I have no noticeable ill effects from having the header on the car compared to the stock maniverter.

Thanks for the replies! I think I'm gonna just get the zzp header and mid pipe since its definatly in my budget and since I already have the zzp catback lol.. Do I need a tune right away once I install the header?

You hit the nail on the head there...I can't stand the sound of these cars with a header installed. Just not worth the extra ponies to me. To most out there I'm sure it is. My music is loud and others don't like that. But atleast I can turn my radio down. You can't turn an annoying buzzing sound down when it's built in

 

[mitdr774]

Annoying buzzing sound can be controlled with proper selection of muffler and resonator. I have minimal rasp with a couple of the set ups I run throughout the year. Not excessively loud either, but louder with the header than without. For example I have the maniverter back in for winter and can run a side exit without an additional muffler. Swap back to the header and I need the extra muffler to quiet down the volume.

 

[Ltz_driver]

Right now I have a zzp resonator and muffler, would that keep the buzzing some what low??

 

[mitdr774]

No clue. It depends on a lot of factors. Chances are that it wont get rid of all of it. Is the resonator and muffler the same diameter all the way through as the piping? I have heard that their resonator chokes down to about 2".

 

[mitdr774]

I stand corrected on my claim earlier. Looking back over data logs and airflow numbers I am sitting about 38hp above factory. This is based purely off of reported airflow numbers though.

I will vouch for the quality of the welds on the BNR header, but have mixed feelings on the other one. I know a few people that have had welds fail on other products and I have a prototype header with some less than impressive welds.

 

[Ltz_driver]

So I've decided to go with the bnr header!! If only they can have them in stock and answer my phone calls lol

 

[DWolfe2010]

i have zzp header and i have ZERO complaints, the welds are fine pipe thickness seems pretty good for its size. IMO its money well spent to say its alot cheaper than BNR headers

 

[Ltz_driver]

I wanted the zzp header cuz of the price but when I called, they told me It would only give me 10 to 12 more horsepower so instead I went with the bad news racing header since they says it's pushing out 30 horsepower.

Its about $170 cheaper. Based on the 4-2-1 prototype that ZZP made, keep an eye on the welds. That being said ZZP outsorced the production header so it may have decent welds on it.

Personally I would go with BNR if I had to buy another header.

That's what I wanted but it was so hard to in touch with them and I was on a smaller budget at time of purchase. Could've been patient and waited but hey I'm a man dammit hahahaha
