firestorm cans

[David451]

Cant find any info on this in the threads, do firestorm cans fit our bikes, sp1 in particular.

Cant afford new cans and see ones for sale at the minute second hand.

The cans would fit if you find the right sized link pipes,the storm link pipes won't fit.
Try looking or buying some sp 50mm link pipes and the world is your oyster then in slip on cans.

Thanks for that.

why not get a cheap set of OEM cans and cut off the mid pipes and use these. They are reputed to be as good as any aftermarket mid pipe for power gains and just need marrying up to a can of the same length to produce a top system.

A good idea.

There is a couple of firestorm link pipes on ebay, can you tell me what the difference is, they are quoted at 51mm outside diameter, but I'm guessing that there must be more to it than that.

It's the link pipes which are the problem. They are nothing like the the SP1 or 2. I kept some cans from my Firestorm and looked into getting them converted when I got my SP. Basically, it wasn't worth the hassle, it was going to cost about £150 to get the link pipes converted and it would have been cheeper to buy ready made link sections from carbon can co or someone like that. The guy was a bit of a purist too and he also said "Why do you want to put crappy cheep cans an a bike like that?" I could see his point, so I waited a bit and saved my pennies and eventually, something came along

Choosing an exhaust for your bike is a mine field, especially with the big twins. If you're not too bothered about small power loss or gains then choose the system you like the look of weather it be big bore Moto GP style cans or high levels with single sized mid pipes etc. Tests by more than one manufacturer have shown that the best power gains come to low level sytems with conical header design, in fact very similar to the OEM system but without being over silenced (by being open no baffles). As i have found out to my expense the end cans regardless of style need to be packed properly (epsecially the carbon cans) and if not the packing can blow and burn away causing power losses and excess noise . The overall length of the system is important (mid pipes and silencer added together) so Moto GP cans would probably show better power gains if the mid pipes were longer reaching them to where the OEM silencer outlet would normally be, but this would look wrong. System diameter is critical as it must be wide enough to get rid of the gases quickly but not too wide that the exhaust gas speed is reduced which is why the HRC systems are fairly useless on the standard engine as not only will it not fit on standard cylinder heads but it too wide a bore and suited to high flow engines. It really is worth paying for a quality system with a history of R&D behind it as its the R&D that costs, if you look at the actual materials involved against cost you could never really have a go at the missus again for paying £150 on a pair of sandles What that chap said to Sppete was right about paying for a proven system IMO.
On the subject of Moto GP styles i think these look the dogs bollocks.

it really is down to personal choice at the end and of course budget but these are classy bikes which deserve the mistress treatment with diamonds

Well I guess that put an end to my plans, I was going to try and fit my blackbird cans on with link pipes but the blackbird cans are 60 odd cms diameter, too big and as you guys say the bike needs a decent system to dress it up a bit. Well I guess its going to be next year.

If you can do it cheap enough have a go by all means but what you need to bare in mind are the setup costs and the re map for the Power Commander which are about £140 a time. Most after market slipons state you dont need a re map but anyone who has had a custom map made after fitting these will say there is normally a noticable improvement afterwards. When i first fitted my scorpion low levels i had a map done and the chap told me he ad taken a fair amount of fuel out so i would notice a fair increase in fuel economy which does help with the SP's awsome tank range And it doesn't take long at todays prices to re coup the re map costs. On the flip side if a new system causes weak running then that can cause machanical damage so its always worth having a custom map made. I think ive had 7 maps done in total, one each time ive added or changed something like exhaust, air box, snorkel, cylinder head work etc. and ive kept all the old maps just in case.
You can run the bikes without a custom map but you wouldn't again once you've had one done once.
