Quiet Quad Exhaust??

[fatjoez]

Hey there

Has anyone had an exhaust/muffler shop custom weld a secondary pipe to the stock 135i muffler to make a quad exhaust?

I'd like to do this but wanted to see if anyones done it before to get their thoughts on it.
I'm trying to keep the volume/sound as close to stock as possible
Another reason is $$$, shipping an actual quad would cost as much as the exhaust itself

So, in which country / state / city do you live? That would be the first step to get help....
Or would you like to drive to, say, east London because someone knows a shop that does it there?
Oh now I get it - you want to know if someone else guinea-pigged already
I'd go to my local exhaust shop. Yellow pages or equivalent should help. And then ask those guys....
Well as I just realize my post does not help much, eh
On a side note: as I ordered mine I was asked how loud i'd like to have it!

Might be more cost effective to get a custom quad
