OPF’s

[Dr. Gaspar]

I'm about to change downpipe but I want to keep the opf so I don't have to cut the exhaust. but to what extent is it advisable to leave the opf and change the downpipe? could it be catless? will it hurt the engine? will the sound be good?

Re: the Milltek opf back from fensport someone posted: how the fuck is someone supposed to spend 2 grand without a before & after video sound comparison? How in the actual fuck do these companies even make a living working like this, I'm supposed to spend 2K and let some cunt chop up my exhaust all based on what, faith?

I can see a sound video of a fucking £10 amazon hoover more easily, but £2000 exhaust upgrade, no reviews/video? What a load of bullocks
