Opinions on next mod please

Came across this a while ago muffler delete with twin tip apparently 0 drone on motorway and quiet till you give heavy throttle

The exhaust on my car is a stainless backbox so zero rust and a nice size single bore but as i have a nice twin tip stainless tip here iv been contemplating it but still really undecided if its a case i hate it i could alway put the original backbox on

This is the exact tip i have

Now heres the video its an auto and the camera is directly above the exhaust so extra noisy (take this into account) thoughts please ?

Be as blunt as you like

Looks a little bit like a small shotgun exhaust which aren't that loud unless accelerating , but when accelerating sound epic, or else go full r*tard and get a straight pipe :)

I'm undecided, I like the standard E39 sport backboxes as is.

If it is fully reversible then it might be worth trying out. But to be honest, I'm with DonB in that I'm a fan of the OEM tail pipe on the 525i. A bit of Autosol on the tail pipe & it looks well, sounds OK under load.

Yeah I'd stick with the big single that's on it

Save up for an Eisenmann Gar!

i like the way it looks and the way it sounds.
i didnt think the 525i could sound so good.
something else to add to my list.

This thread hasn't made it any clearer or easier [emoji1] but thanks for the input folks
