I sold my AA rear mufflers, but still have the X-Pipes(w/cat delete section), Short Shift Kit, and AA Power Pulley with engine belts.
First, the X-Pipe has 3 small dings in the resonator area-not affecting performance, other than that it's flawless with only 3,000 miles on it.-$1400 shipped in US ***New=$1999.99 +shipping
Next is the Short Shift Kit from Active Autowerke. This too has only 3,000 miles on it and is PERFECT-Great addition! It makes the shifting smoother, and shortens the throw just the right amount. I will let this go for $300 shipped in US. ***New=$475.00 + Shipping
Last for sale is an Active Autowerke Pulley Kit. This is the pulley designed for the M3's built prior to June 2008. This has 3,000 miles on it as well and the belt is perfectly fine. I am willing to let this kit go for $350 shipped in the US. ***New= $499.99 + Shipping
All these part WILL fit any M3, whether it be a coupe, sedan, or convertible. If you have any questions, please PM me. I would like to get rid of this stuff pretty soon, but am firm on the prices(I think these prices are very fair).
