Hi,

I know you said 3" Alta exhaust but I have a 2 3/8" Invidia Q300 catback exhaust system that I don't really like. It's too loud inside the cabin for me. It fits 2007-2013 R56. It's basically brand new as I've used it for only 2 weeks. Brand new with tax and shipping was $1300. I'm located in Surrey and I'm willing to negotiate if your interested.

Thanks Logan, but i am interested in minimum 2 3/4", preferably 3" due to upgrades on my car, im running 21 psi boosts through a ported head and need a big diameter exhaust, I think this is the biggests choke point for my HP rite now

 

I think you'll have a hard time finding an older Alta 3" exhaust, but I could be wrong.

If you don't want to wait, I would give consideration to the Scorpion Challenge exhaust:

The Challenge exhaust should flow plenty good for you.
