I just cut the whole pipe and cone thing off and hose clamped a screen on there to act like a spark arrestor and it makes it sound pretty snorty for a 90.
Matt. I restored and modified a couple TTR 90’s. I’m a clean freak with my Bikes but the Cover Plates to the exhaust, I took off and polished them all to a Chrome finish. Looks wicked and easy to do.
I would have done it heaps different, in stead of having to trill the holes I would of cut that small pipe completely out but welded the cone in the same spot.
I just took the entire thing out and then the bigger piece of the pipe were the baffle when it broke off so now it's just a straight pipe and its is fast
Taking the baffles out of a bikes exhaust specially a little 90 doesn't make it faster people think it's faster cuz it's louder if anything it's makes it a bit slower because your looking back pressure I spent 3 years learning mechanics and on such a small engine u need all the back pressure you can get to help propel the bike
I'm not sure on this.. the process should be very very close as most carbs are the same internally, but the jet sizes and disassembly may be different. Thanks for watching!

SMS CUSTOMS nice! Never did the chrome but imagine it would look good!

If I make this exhaust modification, do I have to make any other type of adjustments to the carb ?
some would say yes, some would say no.. I think you will have some lag if you open the exhaust all the way up.. (so you would have to adjust carb)
I'm gonna try this on my ttr 90

brett hagon yea, removing the back pressure will decrease the power
100% right
It's only 6 or 9 more hp
i have a pro circut and its basically gutted out silencer and its loud asf
if you just take the torpede exaust off it sounds like a harley
+commandocuckoo - very true!! good for waking up the neighbors!!!
Wow I wonder if there are any negative effects on engine besides loudness
how much hp gain like .5 or 1
About 1 aint to bad for a 6hp stock engine
there is a little screw by the carb play with that to adjust the idle it’s a little too high
Sounds like something an annoying neighbor kid would drive Lol! Love the videos tho bud!
I just straight piped mine
I have a ttr 110 is it the same process with the carb

What about the back pressure?
good point but i thought back pressure is for valves right? is this a 2 stroke or 4? honest question?
@@CHEVYCAMARO4GEN ttr are 4 strokes
I'm just wondering but is it bad for my bike that I straight piped it I have a ttr90 from 2002
Jacobluke Baker it probably won’t harm the bike but it will make it way weaker
What is all that metal for
Or dont be a cheap bum amd buy the fmf full eaxust for your 90.. it makes a hell of a difference
9.23.22 no ww3
How much louder does it make it?
dylan_mx_bmx it all depends on how much stuff you pack back into it. If you just drilled the holes it would be fairly loud
my bolt won't come out help
+KK Motocross - that bolt is very stubborn!! my only suggestion is to use some PBlaster and let it sit.. You could also heat it up..
I mean whool
FB Productions your bike will run hotter with out some packing or heat wrap and also be louder
Can I just take that whole thing out and leave it
possibly.. It will be fairly loud. you may have to play with the carb as well
Kason Wiese I did years ago with mine, extremely loud and I miss the way it sounds. My TTR125 didn’t sound as good
No one do this it doesn’t work
