do the t1r catbacks have bottlenecks?

Quality on this exhaust is impeccable. Mine came with the addition of bottlenecks tho..

Thats is very strange.
Mine has no bottlenecks, and looks a little cleaner around the flanges...


Don't know what to say, I'd ask the person/company you bought it from what the deal is.

I think is better to ask the place where you orde it from. I think they must shipped you the bolt on version instead of the complete system but gains are similiar.

You can purchase a complete 65mm cat-back, like the one I pictured.
Or
You can purchase a mid-pipe (b-pipe) seperately which usually comes with that type of bottlenecked flange, along with an axleback. 63.5mm for the piping.
Both would effectively create a 'cat-back' system, but one is bottlenecked and slightly recuded in diameter.

Tell me more about this.
I cut mine out, and then started getting CELs, I think. Code 67-1, which has to do with the cat.

Ok, not coming from an expert but here is what I understand.
With such a free flowing exhaust there is not enough pressure, per se, it does not allow the cat to heat up properly, resistance that's the word!
So the bottle neck is placed to put enough resistance to help the cat warm up.
Personally, I have the JDM Mugen Twin-Loop that does not have that there. I don't have a problem, however if I take off my axle-back i get the smell of rotten eggs which means my cat is not doing it's job. Hence not warmed up properly.
That's all I know. I'm sure someone, somewhere, in the archives covered it.

You know, that's interesting. I've never heard about anything like that before. I guess then it would depend on what you wanted more, a few HP, or less pollution, as far as "fixing" it is concerned?

Yea, you're just making S*** up now
I'd think it was made like that to bolt up to an otherwise stock car (which wouldn't have a 2.5" cat). Whatever the reason, that's one sorry looking flange. I'd personally be embarassed to have my name on it.

I can see how you might think it's BS, but it's not and I don't care what you think
granted that is a sorry monkey weld of a flange.

Holy Macro!

My welds also did not look that shitty. I wonder if T1R is outsourcing a new manufacturer? Even my first gen T1R looks much nicer than that.
Don't mean to bag on your purchase, but seriously I think you should talk with R & D

Because they're not.
I think they're made in Taiwan, or maybe China...dont remember which, but not Japan.

You're 100% correct, as we stand today that is the case. However, I remember back in the "gen 1" days, T1R boxes were shipped with a little "made in japan" sticker on them; hence, I was asking if they were still being shipped that way. Anyway, see first post: https://honda-tech.com/zero...age=2 , "T1R is AJ Brand and most of the parts are manufactured in Japan and Canada."

I don't remember if my box had a made in japan sticker, I just cared what was inside
...threw the box away as soon as I saw the blInG y0!

i don't think bottlenecks will make that much of a difference. as ajr and 92typeR said, both the T1R cat-backs with or without the bottleneck show similar gains. 
however, i'd be more worried about the shitty welds. i'm sure r and d will hook you up.
