Alex O - Think you meant 240rat rod not me....
Whilst talking about exhausts, mine is 2.5 stainless all the way with two big silencers in it as I wanted it as quiet as possible- measured at 78dB at a trackday static test at 4,000 rpm. It’s pretty quiet...
Rat rod- what are the wheels on your car? 17inch Peugeot steels?
Oh another thing - buy or beg/borrow an impact wrench, it’ll speed things up no end
Cheers
