Yes it will restrict it and make it run rich but i want a quite bike....

Suggestions please.... The neighbours hate me

You might be surprised....many years ago, I had an interesting conversation with Les Williams, who ran the Triumph road race team.

He created Slippery Sam...the most successful bike to race at the TT ever. A Triumph T50 Trident.

Proddy racing rules of the time were you had to have the standard exhausts, but could gut them for more power. So, they gutted the reverse flow baffles out of the standard BSA/Triumph 3-exit 'ray gun' silencers, and got more noise, but LESS power.

So back to standard exhausts...and five consecutive wins of the I o M Production TT until 1975. By 1976 the Triumph Trident was no longer in production and Sam got retired, unbeaten, as he could no longer be counted as a 'production' bike.

A local MX/Enduro bike shop will have a variety of packing, I find the loose better than the mat, easy to do once you've got the end cap off.

For those that repack their cans, using rivets...

Just in the middle of packing the Arrow on my KTM - I looked around and the general consensus was Acousta-Fil was the best, I ended up buying some of their PTX packing. Theres a calculator on their website, just measure your exhaust and buy what you need. I bought mine from max_torque_cans on ebay.

Very easy to fit - just loosely wrap the packing around your perforated pipe, pop it all back together and after a short while of the bike running, it melts the thermal thread holding it in a sheet and it expands inside the can. I just need to rivet mine back together - I have alloy & stainless rivets, and I'm waiting on a lazy tong riveter coming to see if it'll handle the S/S ones (they're tough to rivet by hand usually).
