I have this one from Amazon by Spec-D Tuning that passed BC Canada air care with the O2 only in the #4 tube:

I've since done an O2 relocate to be upstream of my high flow cat so it reads all 4.

I still passed aircare before the relocate, NOX was a little high while CO/HC was low. Could be the leaning out from the O2 but was still okay to pass.

The fitment of the header was perfect and went from the super short 4-1 to the longer DC type 4-2-1. It was with the cat back portion of the exhaust that fitment was a little off but not unbearable.

This was on the 95 D series 1.5L but I believe is still relevant to the D16's.

IV been thinking about building some exhausts for my cars since they're old, the mufflers are both crap and the whole pipe is starting to get scaley with rust around the elbows.

plus I really hate the way the cats are stock, I would much rather have a nice gasket than the stock setup.

This means nothing without numbers. What are the limits there?

Hows it work on a 4->2->1 exhaust?

if I'm not mistaken it wasn't after the 2->1. Hmm I can barely remember disassembling that crap

TomCat39

Max is HC 0.37 g/km CO 6.21 g/km NOx 0.93 g/km in 1997. Don't think it's changed much since then.

The later air cares I have don't have the max numbers.

acmoc

Same, after the 4

Thats not true though, my completely stock d16z6 for sure doesn't read the o2 sensor based off all 4 ports. Its hard to tell with the heat shield but its certainly before the 2->1 connects into 1.

You didn't specify what car this was put on, info isn't valid and just doesn't make sense.

/thread.

I dont really understand any of this. Cheap headers might break sooner but if they're installed properly and the o2 sensor is in the same position it would be in a stock vehicle I dont see the problem

And for a $50 header no less.

TomCat39

So far my 50 buck header is doing well, then again it is stainless steel.

The O2 bolt is rusting from two salty road winters but the header itself is in good shape.

I might get in the habit of pulling the bolt once a year and putting copaslip on it since it's steel and not aluminum.

I think I'm nearing three years of abuse so far without issue except backing into a curb and bending my muffler tip a bit. I think this will be my third summer.... Foggy memory.

And I've learned, if any muffler has a removable silencer in the muffler tip it vibrates and creates that rattling sound on high revs. I've thought about getting a cobalt drill bit and seeing if I can put two more bolts in to hold it, two bolts is not enough where 4 might just secure it properly.

But that's on the muffler end not the header end. Oh and I also pulled the steel wool "padding" from between the silencer and the muffler insides. I replaced it with a 3 inch thick fiberglass matting without the fiberglass epoxy. The glass handles the relatively low heat and won't rust and provides a solid amount of padding between the welded tip and the silencer bolt on tip.

If your eBay muffler is working then more power to you. I've run them. No complaints. But if you have issues and want to complain then maybe next time don't cheap out. But when they don't make any real power in the first place...

TomCat39

I hear you. I've been content. I wasn't after power. I did like the sound difference. Not too loud but sounds a lot more than just a economy car. Has made the car a lot of fun to drive.

The real purpose I upgraded the intake and exhaust was purely to let the motor breath better. I was hoping it would aid in improving my fuel economy, unfortunately, the sound hasn't helped my discipline any, if anything it's made my lead foot a little worse.

It was also fun learning the basics of exhausts and the challenges that comes with them.

And the best part is, it didn't cost very much so if it does fail it's not like I spent a fortune on the possible disappointment.

Overall, I've been quite pleased with the purchase. And my work installing it.
