Introduction

After purchasing the Spoon N1 exhaust last spring in a group buy from Clubrsx, the natural next step was to get the Spoon B-pipe. Spoon distributers are far and few between, and I found it quite challenging to find a place that had the Spoon B-pipe in stock, and even harder to find it for a reasonable price. AJ-Racing in Canada had it in stock for a good price, but shipping and import fees would make it a little expensive. Recently Chris Dye, founder of Clubrsx had a falling out with Spoon, and descided to clearence out all his Spoon merchandice. Well, his loss is my gain, and I picked up the B-pipe from Clubrsx for $350 shipped.

I took off my N1 exhaust for the winter since the MN winters are very hard on exhaust components, so I will reinstall it and my new B-pipe in the spring. I will update this page with new pics and info on the install as well as performance gains then.

Here are some specs on the Spoon B-pipe:
Pipe Diameter: 60.5 mm (2.38 in)
Weight: 5.9 kg (13 lbs)
Flow Volume: 135 liter/sec
Installation
The install was uncomplicated, but proved slightly challenging due to the fact that my stock b-pipe has had almost 2 years to bind to my cat. To install the pipe I first applied some liquid wrench to the three nuts/bolts connecting the b-pipe to the cat and gave that some time to set in. I then disconnected the muffler/exhaust from the b-pipe and removed it. I then removed the three nuts that connect the b-pipe to the cat with a 14 mm socket and the longest ratchet I could find. I ended up using my torque wrench since I don't have a large breaker bar, but a breaker bar would be preferable. I also gave it a whack or two with a hammer to loosen up the rust. Once the nuts were removed I was able to remove the stock b-pipe. I tranferred the rubber mounting bands from the stock components to the Spoon exhaust, and reassebled the exhaust first by mounting it to the car, then bolting the muffler to the b-pipe, and finally bolting the b-pipe to the cat. I used the Spoon supplied gasket, bolts, and springs for mounting the muffler to the b-pipe, and the supplied nuts for connecting the b-pipe to the cat. Also included with the b-pipe was a washer/gasket which I think was for the cat/b-pipe connnection, but it didn't seem necessary so I didn't install it. I tightened down the b-pipe bolts to 25 ft-lbs, tightened up the muffler bolts until they were tight, and I was done.

Comments: The B-pipe came very well polished to a fine mirror shine. Even so, I'm on a crazy polishing kick right now, so I gave it a once over with the polisher. The welds look great, and as expected it fits perfectly with the Spoon N1 exhaust. I will add more comments once it is installed.

Update:  Well I finally got around to installing the b-pipe, as well as re-installing the N1 exhaust. I was hoping to install these separately so I could distinguish thier gains, but I was too impatient so I did it at the same time. The performance gains were very good, especially in VTEC. The gains were definately greater then when I installed the N1 exhaust by itself last spring, but it's hard to be exact without dyno numbers. The exhaust note is definately louder, much louder then stock, but only a bit louder then with the N1 exhaust. It is deeper sounding from 3-5k rpms, but really roars above 5k. Overall I'm very happy with this mod, with the performance gains, sound, and oh man, does it look nice. Even though it's under the car...
