I bought an LRD Pro 4 Series slip-on today for my 05 trx 450r and it seemed to fit loose over my factory pipe.
The instructions say that this slip-on will fit any year trx450r and to use high temp silicon were the pipe and muffler join.
I think that the 06-07 factory header pipe is a little bit bigger diameter were it joins the muffler than the 04-05. Is this the reason why my 05 is a loose fit and why didn't LRD take into consideration the differences between the header pipe size of the 04-05 and 06-07 450r?
The last time I used high temp silicon on an atv header it melted the orange RTV high temp silicon and then leaked.
