exhaust change time is this a stupid idea

[lawb]

changed the whole system on my last one sounded good but wasnt enough

this sounds silly to even think about what do you think about cutting the pipe behind the cat and clampin or welding a universal back bok in the place of the cat

now makin it fit is head work but i dont ind that but i want to know if it will be no good for the engin or performance ie back pressure ???????????????????????????????????????????????????
if your cleaver than me
let me know what you think

Why mess about putting a back box in halfway through your system?

Just get a straight through pipe mate, no silencing or cat. Just be careful when the MOTs due and avoid motorways
