PM tuning

really wanted stainless arent they just steel,just so it lasts and minimal cleaning unlike chrome ill give them a look cheers

but is stainless the best material to use for a two stroke exhaust
I've read not, but can't recall the reasoning behind it

I agree PM pipes do work well, but you say its a torqy motor If it isnt a revy engine and pulls hard, a Taffy pipe or JL3 may be worth looking at, as well as the PM. what gearing are you pulling? "Stainless tends to crack"

not sure on gearing as reluctent to take any thing apart whilst running so well ,at the moment it has wot looks like a converted micron from a rd and i was told at a rally last year looks like rd350 reeds were used,nothing wron with pipe just not my cup of tea as it sweeps up to level of top of panel,ahh had read steel was better for pipes didnt know stainless cracked though ,so scorpion not a good move thhen cheers peter

Scorpion were not rated at all in the last exhaust shoot out in Scootering a couple of years ago.
Most other pipes pissed on it for one reason or another.

some feel stainless does not perform as well as steel but it depends who you ask as i have and seem to get a different veiws ,personally id go for steel as it will be less likly to break

i was told its something to do with the heat , stainless will last longer and won't rot but is brittle so prone to cracking have a mate murph with a ts1 with a scorpion on and he couldnt keep the end can on, forever snapping off ,i think he ended up with a scootrs pipe, sean might be able to tell you better

I mIght be talking out of my arse here
But, doesn't a mild steel exhaust (chromed or not) help the exhaust pulses? A stainless being a stronger less flexible metal by nature doesn't help the pulsing at all
