Anyone have problems installing cat replacement from Triumph

[houkster]

My main problem was getting my last pipe on - left side one. The bolt holes wouldn't line up and I had to loosen the whole shebang so I could pull left side cat repl. pipe back further. Now I should clarify that I bought the replacement used from one of our members (could he have bent a tube?) and he shipped it USPS ground 2000+ miles with NO PACKING. It was also a bear getting the old cat off because I didn't realize the one holding bolt was threaded through not only the bracket, but a tube thru the grommet assembly which had a large washer at the end. The washer was turning and the bolt had cleared the plate....what's wrong?....it won't come out! Hold the washer and keep turning the bolt!
You can't see the sleeve attached to the washer as it's in the grommet.

O.K. tors plus cat removed is a bit loud. Has anyone out there put their stock silencers back on after cat removal, and what sound did you get. I wasn't happy with just the tors. Does putting the stocks back on take you from a 7 of 10 sound level back to about a 5? Or is it about as quiet as tors and cat box still there??? I assume it also knocks out the popping on decel quite a bit - is that why guys have put 1 or two back on? It's a strange 'backfire' in that it doesn't start the second you decel, but waits into you're going much slower in that particular gear. My moto guzzi with crossover and pipes started the growling as soon as I reduced throttle.

P.S. Thanks guys for the tip of how to 'gently' remove the pipe gasket out of the cat box. Took a while but was successful . I assume Triumph doesn't send a new one with the cat replacement (?).

Describes my bikes sound exactly.
I have the TOR's with no cat. The dealer fitted it, so can't help with fitting problems. I try & use just a few revs when slowing, rather than throttle off completely - that way I reduce the popping & farting somewhat.
Reading what the others do with their Tuneboys, that is the way to go, I think, in order to maximise power & fuel efficiency, and from what I read, it may also drastically reduce the backfires.

My dealer fitted my TORs and bypass as well, but I do know that some people put back one stock pipe to deaden the noise a bit. I haven't heard the combo but it should be what you're after if the full TORs system is too loud for you.

Either that or just do a few hundred miles with no ear plugs. Yer ears will hurt at first but after a while it won't bug ya at all. Wonder why? :lol:

Seems like putting 1 or 2 stock silencers back on would cause some sort of strange imbalance engine pressure-wise. Will try this for awhile and probably eventually stick the 3 stockers back on and try it out at least since I own both sets and the slashcuts can be transferred to the stockers I believe. I don't mind the popping as long as it's not a true backfire, would probably prefer it start as soon as I cut back on the throttle though.

you know what they say, if it is too loud, your too old....maybe that only applies to music? Anyway, I have the cat delete and the TORs, and I love the noise that comes out of the beast....sounds like an old WWII fighter plane in lower gears, and a WWII bomber at higher gears...I love it.

Now, nobody should get their knickers in a twist, I am just joking about the too old thing...
