just weld a plate in , i have done that and get some brace bars to go underneath to give it the strength it had , took a few hours to do !!! 182 boot floor is over a £1000 new and would be a absolute nightmare to fit , would need to cut old boot floor out and cover everything in and under the car up , just be carefull when cutting spare wheel well not to cut anything when cutting it out as the fuel lines go underneath the spare wheel well , a lot of hassle for just a exhaust to be honest , i am just fussy hence why i took it out in the first place
