3 weeks lead time for delivery for a BCS is the only downside at minute :(. Am impatient lol 
Thats where a big company like Milltek will win every time. I could order a TBE and it would be on my doorstep at 9am.
True if the BCS is really worth the wait and a lot better than the milltek I may just bite the bullet and wait.
What way is it better?. Sound? Power?
Any links to a Cat back non resonated system on a mk5 gti ?
cheers
