Notice the difference in piping.

The infamous bottleneck


I think you can tell which is new, and old.

Both have the hole pre-drilled for the silencer.

Enjoy.

 

good info B!

 

Thanks for the pics Bryan...

 

Thought there would be some interest in these, since a lot of people were asking about the differences.

I am NOT selling these. One is a friends that I just put on his car, and I thought I would snap a few shots to compare.

Thanks.

 

nice info!...where did you source out two n1's?...

 

 

you can tell which one is new too! you gotta polish your tip

 

Good comparison

 

Good job

 

Thanks heaps

 

you sir, are what i would call, the man

to you

 

man...loving that piece! thanks for the "ihn-foe"

...will work for spoon n1

 

So did you mod it yourself or is that the new way spoon is making their axlebacks?Sorry I did not read any previous post about it

 

look for a bottle neck like pic

 

let's hear a sound clip!!

 

Woo Hoo. I got a new one!!

 

I actually saw the new one in the above picture a couple of weeks ago but didn't measure the tubing OD, I've read where it is larger than the old style. The quality of this piece is top notch and the small tip looks very nice . However, the inlet of this new axle back piece is still set up to bolt onto the stock B pipe and it was measured at only 2" ID, where the OD of the main tubing is at least 2.36" and some people on the board have said it may even be close to 2.5".

 

Any plans to do some dyno comparisons of new versus old?

 

If anyone has a Spoon N1 rear section they want to get rid of, I have a Mugen Twin Loop rear section (meant for 99Si, shortened 2" to fit Integra) that I am willing to trade.

I rode in Type Rare's car in BC and I like the Spoon rear piece.

 

You are correct Sir, The piping on the newer N1 is larger. I dont like the flange, though. Sorry, I should have taken a few pics of that.

No plans to dyno both on the same car, although it would not be hard.

The newer N1 went on Ross' car, and its still slower than mine in street trim with the stock exhaust

 

Hey how did you get your hands on my exhaust?!

F bottlenecks! I am dynoing the car soon enough, but Bryan's car is set up a bit different. He has a stock ITR b-pipe with the bottleneck cut out by Dave @SMS...I have a Type One B-pipe that still has a bottleneck in it. he has a modified stock ITR airbox and I have a Comptech Icebox. We have the same header although mine was modified by Dave@SMS. The cars should be more or less equal in terms of hp though. hmmm

 

nice stuff

 

sound clip(s) please

Alex

 

Bryan has some nice in-car clips of his car...Bryan, you should post the one with my creative point-by
