I thought my pipe was oem but it looks like it is not.It has a 4 into 2 header where acording to parts drawings it should be 4 pipes then a collector.My head pipe has 2 tubes come together on top and two come together bellow the 2 top pipes.It has 2 mufflers in back which I always thought were oem but I dont know.Who made a headpipe like that ?Its one piece till the back of the collector where the mfflers clamp on.
Some pictures would be great. Might be a cool old vintage system from the aftermarket.
Interesting!
I will take pics but I will need to email them to you I dont have pics hosted anywhere but on my computer.

I just posted pics in the gallery
that looks like a supertrapp header with some home made midpipes splitting it into two.
nice........ i would have to put supertrapp internal disc silencers on it though :good2:
Kookaloo!
Looks like a vintage Kerker 4-1-2 system to me
My best guess so far was Kerker but I have not found any info on a 4 into 2 Kerker yet.She eats up the highway no problem and the pipes sing a tune for me at the same time.Why do most members run a 2 into 1 pipe ?.As soon as i get my trans fixed (2nd + 3rd) she will sing even sweeter.Forks,trans and a new chain and sprockets are at the top of the list of things to do.
mostly we run 4/1 pipes because thats about all that has been offered in the last 10 years or so.
ideally i think the perfect street pipe would be the stock headpipes and collector with custom midpipes and dual supertrapp silencers. nice and throaty with good flow without having to run a wide open single silencer.
IMO the stock exhaust gives a more even spread of power across the revs.... albeit a bit restrictive but i believe that to be the silencers more than anything else.
there was a definite drop off in bottom end torque (below 4000rpm) when i first swapped the stock exhaust to a 4/1 but the kookaloo zone (you know where it is ) got much better
Kookaloo!
What you have is a Bassani setup -Partly. Looking at pics someone took header and welded a homemade y-pipe to header. You can tell this by quality of the home made welds off header collecter. Then Bassani use to manufacture what they called "Slip-on Silencers". The baffle was inserted into cylinder and you could buy them from 1-1/2 ,1-3/4,2,2-1/4 and 2-1/2 . Funny thing about this is i was finishing a Kawi Elr that i was looking for a "Bassani Superbike Header" system that i ultimately found but until i found it i have several sets of the "Bassani Silencers" that i fabricated to adapt to a Kerker Header. The main guy at Bassani is "Frank" 714-630-1821. I had him make me 2 sets of baffles- 1-3/4 ,2,2-1/4 and 2-1/2 for my Elr bike because i didn't know how loud was loud and also for tuning reasons. If you want Frank to make a particular baffle you have to send him example. Bassani now only make pipes for cars and harleys- but if you send him sample and catch him on good day he will make. I can take pictures of what i have - they are new in box - so you can see what you have. The only help i need is how to download pictures to this site - I am a dumbass when it comes to this but i will try to post. ALSO TO - if you need cones,megaphones and anything to fab-up your own exhaust system go to www.coneengineering.com (http://www.coneengineering.com) they are out of los angeles ca and this is where Kerker gets their raw materials
I want to thank everyone for helping me out :good: I passed up a old FJ on 53 tonight I had to slow down to double check he was only only going 55-60 mph.It did not look as nice as mine but it was nice to see another FJ on the road.He had lower side covers on his bike and a little lugage on the back.
Im happy with the pipe and I like the twin mufflers.Has anyone run 4 pipes all the way back 1 pipe per cylinder.I have run triple pipes on my waverunners (3 cylinder) h.p. went up from 135 to 170 h.p.
Just learning this bike stuff so thanks again for everyone's help.
Ok - I uploaded pictures into gallery under misc fj pictures. You can see what a full comp "Bassani" system looks like - its on a Kawi , and what the baffles and silencer cylinder looks like. If you decide to fab your own system i mentioned on earlier post where you can get raw materials. If you are making exhaust system for daily use and want deeper tone a 4 into 1 will great - just have to play will size of chosen baffles before jetting becomes part of equation but - if you decide to create a 2 into 1 times 2 - Do not pair number 1 and 2 on one side and 3and 4 on otherside. Cross over pipes 2 and 3 - so that 1 and 3 are connected to one side and 2 and 4 are connected for the otherside. Much easier to jet this way,more responsive and no there bike will sound like yours. As a beginning project you could use stock header because pipe bends and flanges are already done and just start your cutting and fabbing off underbends under motor. Earlier kz900 and 1000s use this style pipe design. Just take your time and tig weld looks cleaner than mig weld. It is a little tedious ,but its not hard. Good luck. I also uploaded differences in Supertrapps.
I also uploaded a 2 into 1 times 2 exhaust system that is stock on a 93 secaii 600 that i also have. Factory mates pipes 1 and 4 together on one side and 2 and 3 together for the otherside. Larger Kawasakis like 1 and 3 for one side and 2and 4 for other. ANYBODY OUT THERE KNOWS WHICH OF THESE EXAMPLES BETTER FOR FJ? This is if you go with 2 into 1 times 2
Thanks for posting pics. :hi:
:good2:
I standing by my thought that it is a Kerker 4-1-2 system.
Someone else has to remember them, I can not be that old, can I? :blush:
I noticed your missing a couple of the bolts that hold the canister guts (baffle) in place. Our local Ace hardware had perfect replacements on hand. I've got a couple extras, if you want them, I'll mail them to you.
A picture from the back of the canister/muffler would be nice, at least then we could confirm the canister/muffler are indeed Kerker (or not).
It was funny when I overheard a kid talking about the "new" Akropovic 4-2-1 systems a while back, heck, they've been around a while.
The biggest advantage was increased muffle volume over the 4-1 systems, as well as the asthetics of a dual exhaust system.

I will take some pics for you of the mufflers
Its NOT a Kerker. Before becoming a painter ,Early in my career I use to work for Kerker as one of their welders. This is why i have more info on different exhaust systems and contacts. I posted pictures in gallery. Look at the "Bird Turd" welds that are on back of header in "Scott's" pics. Its is NOT a Kerker - It is homemade job with Bassani silencers.
You may also have a Kerker baffle in a Bassani cylinder - it looks like a pieced together system just by going by quality of welds.

I truly think you are wrong, time will tell.
Others: Here is a link to a craiglisting that has a picture of another Kerker 4-1-2 system.

The picture has been uploaded to the gallery section.
I remember when the Kerker 4-1-2 systems first came out, and I do also remember the welds were nothing to be proud of.....
Looking forward to seeing those pictures of the end of the canister, if they do not look like Kerker canisters, I'll quickly say as much.
Until then, they sure look like the Kerker cans, not Bassani.You know why they look like Kerker cans? Because it is a Kerker system. :i_am_so_happy:
I put a couple more pics in the gallery.Either way Kerker or Basanni i like the pipe :bye2:

That's 100% KERKER
Just as I remember, their infamous 4-1-2 system.
:yahoo:

Akropovic 4-2-1
My typo - meant to type 4-1-2 :shok:
No - its not a Kerker system. Yes i will agree that it has Kerker baffles now that we have good pics. But you are asking what System is on the bike. Your system is welded completey solid. We would of never of done this at Kerker. 1- we could not of shipped it that way. 2- We always made a collecter slide into a collecter so if you had to remove header to change oil you wouldn't have to disassemble complete system. 3-Collecter into collecter with clamp design allows for expansion and contraction and vibration so the system wouldn't come loose everytime you rode it. Just because someone puts Kerker baffles on doesn't make it a Kerker system - Alot of people welded y-pipes to headers then installed baffles like the pics of Suzuki. Trust me - Listen to someone who worked for Kerker and not hobbyist - we would never weld a system solid.
I think this will end your search and debate. I just called old owner of Kerker - who now owns starcycle.com. I left Kerker in 83 but stayed in contact with him over years and he said he NEVER made full exhaust system for fjs until 1990 and they were 4 into 1 systems. He worked along side with Supertrapp because they already had the "Tooling" since 84 for the fjs - 4 into 1 systems -and sold Kerker to Supertrapp 1991 - so like he said the 90 4 into 1 system was assentially a supertrapp with a Kerker baffle. Regardless, Enjoy your FJ and glad i could set you straight.

Thanks for the additional pictures, they confirm the canisters are bolt on and that the system is not a one piece welded system.
It's a beautiful vintage exhaust, odds are it is one of the few remaining KERKER full 4-1-2 systems.
Bottom line, it is an aftermarket system, not stock.
I've been involved with motorcycles sinces the seventies, just like many of the members in here.
A lot has changed, and a lot has remained the same.
When I drop the motor to do the tran's gears whats a good way to clean up the pipe and paint it.
Have it ceramic coated. :)
