If cash is easy, I'd say $700 total but shipping it will be quite a bit.

I just hit 80K....and here's my laundry list of my most recent repair (the primary was a CV boot and the rest was preventative/due items). YMMV.....

CV Axle (boot went bad, detected it early but no more grease and I did not like the sound coming off of it on the way to the shop ) so I'm going with Axle Replacement
Engine Mounts & Tran Mounts
Power Steering Reserviour and Hose
Guibo
Vanos Gasket Seal
Total cost was about 2X your exhaust

I have the Dinan exhaust. Love it.
Just consider the $$$ on repairs to come.

Luckily for me, my aftermarket warranty has been very good with my claims.
