Does anyone have a picture of the SMSP custom B-pipe flange (see picture below) welded on the Type-R B-pipe? I'm curious to see if the custom B-pipe flange fits over the stock B-pipe or if the B-pipe was expanded and custom B-pipe was fitted inside. Any information and pictures would be greatly appreciated. BTW, I did a search .



Also, is the Type-R B-pipe piping single-walled or double-walled? I have had two muffler shops tell me that the piping is double-walled. The first muffler shop, initially stated that the piping was double-walled, but after further inspection determined it was single walled. Another muffler shop was pretty adamant that it was double-walled.

Fits inside. Stock B pipe gets expanded and the adapter fits inside.

 

what the heck is your avatar doing with that sway bar looking thing

 

I would think that would be the preferred method. But the first muffler shop told me that stainless steel doesn't expand that easy and it could split. Does anyone know if that is true.

I will let you be the judge of that . BTW, that isn't me.

 

That avatar is from an old grassroots motorsports magazine.

and yeah, muffler shops swear that the integra b-pipe is double walled. it isn't, though.

 

the bottle neck is cut off and the "B" is expanded to accept the taper cone... I will be getting this done next week and will let you know how it goes.

 

Cut the bottle neck out and expand away, you won't have a problem. If a shop still gives you a problem show them the joint right after the resonator (expanded/slip) and show them it can be done without a problem. I think some muffler shops just don't want to be told how to do things.

 

That is exactly what I'm finding out.

 

Bret,

Take it to a Tuffy around Columbus. I have had good luck with the one on Brice Road on the east side as they do a lot of custom stuff. Actually, they were the one that took the restriction out of my stock ITR B pipe.

MD, in your article you state "you can purchase a tapered flange that is 2.5 in. outer diameter (OD) at the opening which connects to the cat and 2 3/8 in. (60mm) OD at the Bpipe exhaust end."

For the ITR stock B pipe the adapter has a 2-1/2" ID x 2-1/4" OD. Actually all the adapter for 2-1/2" cats have a 2-1/2" ID since the cat is also 2-1/2" ID.

BTW, H-T needs a spec/article section like you guys have at Team Integra.

 

Hey Dave - How much WHP is this flange supposed to put down?

 

Jason picked up 4 whp across VTEC when he had the Toda header, 2-1/2" Carsound and Tanabe RM. The Tanabe RM has a 2" OD x 2" long bottle neck.

SMSP,

What is the longest B-pipe flange that you sell? I have a '94 GS-R so the Type-R B-pipe is already 4.5" to short. I will loose another 2" when I remove the bottle neck from the B-pipe. And then add another 2.0"-2.5" when I get the B-pipe expanded. So I'm looking at custom B-pipe extension flange with a length of 8.5"-9.0" long.

Also what is the thickness of the flange?

 

I will give Tuffy a try. I work up at Polaris and there is a Tuffy nearby. Did Tuffy have stainless steel piping when you had them take out the restriction from your B-pipe?

I have been talking with a guy at Monro in Dublin and he has been very helpful. Today at lunch I bought a 2.5" exhaust flange at Jegs. I also printed a picture of the SMSP custom B-pipe flange and took it to the guy at Monro. He felt that the exhaust flanges from Jegs were not thick enough and they could warp which would cause exhaust leaks. He also recommended purchasing the custom exhaust flange SMSP since it appeared to have thick flanges, it has a nice smooth taper and it is stainless steel (all good points).

 

Only a handful of places around Columbus has SS. This Tuffy didn't, but then again they only charged me $15 total. Some Tuffy's do have stainless though. Beany's on the east side has stainless, but they are major pains because everyone there is stupid.

 

The flange is either 5/16" or 3/8", I'll have to measure. For the above set up you can just cut the ITR flange off and expand the bottleneck out to a 2-1/4" ID to receive the adapter. I can probably do a 8" long adapter.

 

Beany's was the place that the guy from Monro recommended, since they did custom work and they used stainless. I went there yesterday at lunch. The guy from Beany's was the one that was adamant that the pipe was double-walled (which is incorrect). He was also adamant that the 2.5" exhaust flange would be to big to mount up to the stock cat (which was incorrect). All around he wasn't very receptive to the idea of extending and expanding the B-pipe. Get this...he had three suggestions. First suggestion, take back the Type-R B-pipe and get the correct pipe for my car . Second suggestion, buy a Magnaflow cat-back exhaust from him . Third suggestion, have him make a 4.5 extension for $85 . All around I wasn't impressed with Beany's.

 

I measured the stock flange thickness and it is 5/16". The exhaust flanges that i bought from Jegs were 1/4". So this is only a 1/16" difference. In your professional opinion would a 1/4" flange be to thin?

SMSP, can you IM with a price on the 9" long adapter? Also, what is included with the adapter (eg. nuts, bolts and gasket)?
