Ever think It might be just a bad exhaust or have there actually been other documented cases?
I am currently running the HKS on my 370Z and had great gains with it and test pipes +22whp so I am happy.

lots of people found this on their hks exhausts. That's why so many people have the maganflow xpipe put in. ARK makes basically the same exhaust with what looks to be the sme maganflow xpipe everyone else uses.

So you went for the nismo Z and then went cheap on the parts for it? You sort of just defeated the whole purpose of buying a numbered nismo car. Why not just buy a base Z and throw on a knock off nismo parts/body kit of lesser quality? Anyway, this isn't another "authentic vs knock off" debate thread. It should be kept on topic relating to the HKS exhaust and a problem somebody thinks it may have. There's still no solid proof this a flaw existing in every exhaust hks produces. Nobody has shown a picture of a newer exhaust, with a picture of the blockage and proof that it's an authentic piece. Until that happens you can think what you want about HKS and their parts.
I plan on taking mine apart this spring and finding out exactly what's going on in there. If there's a blockage and the exhaust is an overpriced piece of crap maybe my opinion will change lol.

Because I did the correct research and didn't overpay for something that was just as good or almost as good as the original product. Don't be sensitive now just because it seems like the knock off was the better buy...

Again, off topic but not being sensitive here. You're just hypocritical in the sense that you buy an authentic nismo branded car which is a unique model but then buy knock off parts for it. That's all. Whether the knock off was a better buy is your opinion since people have experienced a lot of rust issues, fitment issues, and weld quality issues with the knock offs. The only problem with the authentic hks is an alleged one at best. It hasn't been proven definitively. The welds on mine look nothing like that picture.

I personally don't care if it is real or not but I certainly don't think any proof has been shown that HKS manufactured this exhaust. Sure it looks the same but fakes usually do
show me a bill from an authorized HKS dealer then we will have proof

This has been known for a while now. Just search and you'll find posts about it. I posted something about it years ago. I hacked my hks exhaust up and found the same thing.

I had a local muffler shop weld the maganaflow xpipe in and the sound "smoothed" out a little. Maybe it's part of how HKS achieved the sound they're looking for by causing some turbulence. After about 4 months of swapping that out I sold the exhaust and bought a Tanabe and never looked back.
