| My ST4 came with cored standard cans when i bought it. Its passed three MOT's like that as well (the last one was after the new rules came into play). Its seriously loud, never had the slightest problem with the police or anyone else come to that. The cans weigh next to nothing becasue all the insides have been taken out. Got a standard set off ebay (for £46 last week) just in case!
Much more cost effective mod than paying hundreds for fancy carbon cans that give you a 2hp increase that you cant use anyhow and will certainly fail the test due to the not for road use stamps.
Like Jon said, some people on here need to get a life. |
