looking at getting the storm

But I do have a couple of questions

A friend of mine that got a thunderbird when they were first released had the long tors put on and the appropriate flash put in. He tells me the decel popping thru the exhaust was quite bad and use to drive him crazy. Now I quite like the appearance of the short tors but I am worried about this same problem if moving away from the std pipes.

My question's are simple

1 Does the 1700 suffer the same decel popping as the 1600 does (I would assume it would and possibly be even worst)

2 Has Triumpth's tors tunes for the thunderbird gotten any better since they were first released to perhaps cure the above problem

3 Is there any actual real world improvement in performance with these pipes or is it really more about sound

4 Quite off topic but I have read the 1700 when it comes std from the factory comes with a bigger cat than than 1600 has anyone else herd similar ???

Any feedback on the above would be appreciated thanks

Short Tors look 100% better and come with the added benifit of giving you access to the rear wheel nut.

Popping , a bit , worse than a 1600? Not sure really as it isnt really a loud pop as more and coughing of a bloke who smokes 100 woodbines a day.

Power , couldnt help as I had the shorties with the 1700 bb kit . Daz knows more about that as he tested a few.

1 Does the 1700 suffer the same decel popping as the 1600 does (I would assume it would and possibly be even worst)

Mine didn't. I bought the 1600, ran it with stock pipes then tors, tried tors tune with stock pipes too. Nothing removed the popping. Got the 1700 kit installed and it hasn't popped more than 5% as much as it did as a 1600 since. I have tried the 1700 with both stock pipes and short tors. Hardly any popping. Now running custom tune with 02 sensors removed, still almost no popping.

2 Has Triumpth's tors tunes for the thunderbird gotten any better since they were first released to perhaps cure the above problem

Not that i'm aware of

3 Is there any actual real world improvement in performance with these pipes or is it really more about sound

Short tors make a very considerable difference. When it was a 1600 it took the bike from where i didn't think i could be happy with the power to where i knew i could. Probably 6-8 HP and probably around that in torque too. Well worth it to say the least. Tone is nice too but not too loud. Had the long tors at first and they made ZERO difference in power and sounded nasally. From what i've heard from others they may have changed them and they are now better. But the ones i had at least were [email protected] remember to get the proper tune with the pipes or they will actually cause a LOSS of power !

4 Quite off topic but I have read the 1700 when it comes std from the factory comes with a bigger cat than than 1600 has anyone else herd similar ???

I think thats BS, and would put money on that. The 1700 BB kit sure doesn't come with a bigger cat, that much i'm positive about.

Thanks Daz, did you notice a difference in exhaust sound going from the 1600 to the 1700.

Also a lot of bikes have an air induction system (injects air into the exhaust manifold to assist burning of any unspent gasses in the cat) and simply disconnecting these can help with the popping problem.

Does the t/bird have a AIS ???

Another question, I note the t/bird comes with ABS option, I have found some ABS system's that crude and primitive your better off without them, but a good one is very worth while.

Has anyone tried the ABS system on the t/bird and could advise ???

On the subject of the short and long TORS does anyone know if Triumph have a different tune for each pipe ??

1700 is a little deeper sounding. Not big, at least to me tho some seem to think it sounds a lot deeper. The first run of Tbirds that came out in july '09 has air injection. Triumph did away with it soon after i believe starting in the '10 model year because they realized the bike just runs so clean it didn't need it. Even the first bikes WITH it in the beginning (like mine) didn't have it enabled from what triumph says, tho i'm not so sure about that because i think the "SAI" enable check box was checked in the tune.

And the Tor tune is for either pipe, long or short. Even the aftermarket pipes like BC customs use the triumph tors tune.

by the way, is your Vmax the new 200HP one or the older model?

Its the new one, and its an animal the sort of bike I will never sell.

I'm just looking at another bike that I could use for more of a touring bike (Vmax is terrible at that) and a bit of two up riding.

Back to the AIS are you saying they don't even have the plumbing for it on the t/bird now ??
If they did have it on the very first lot of t/birds, that could be why my friends one suffered so badly from the popping

Also do you find the 1700 to be not as refined as the 1600 ie more vibration ect

I like you am considering a thunderbird. Today I went to take a second look and get some out the door prices and vin for insurance quotes. While I was there I looked at the exhaust on a storm and a 1600 parked side by side and couldnt tell any difference in the exhaust/cat.


Based on looks alone the short tors are best in my book! I havent even heard what the bike sounds like with the other pipes on it. My test ride was on a storm with the short tors and it was a pleasing growl that wasnt too loud at all.

correct. They removed the plumbing starting in '10. Only the pre-order batch sold in mid '09 had the plumbing.

I dunno, but mine is the first one with the plumbing and after the 1700 kit was installed like i said the popping was 95% gone.

I've heard some say a bit more, but i noticed absolutely no more than before. I've also noted people saying it feels sorta "cruder" or something to that effect. Again i noticed nothing. Possibly the vibration changed a bit and got more low frequency, ad that may account for those opinions from others. Not everyone reacts the same to things like that. To me the bike just sounded a little deeper and the vibes got lower in frequency which is a good thing. But both were rather subtle.
