I wish I had found this thread awhile ago it would have saved me the trouble:
I purchased a Agency Power Exhaust System from Vivid Racing for my 2009 Porsche Boxster S 987 Gen II with DFI. A representative from Vivid Racing stated it fits this specific make and model vehicle.
Turns out it does not, fitment is different for Gen I and Gen II cars. I contacted Agency Power and received confirmation about this from a rep named Matt Jobin, "We have not installed one of these on a 987.2. This is designed to fit the first Gen 987"
I had the exhaust professionally installed and the installer modified the exhaust for fitment (shortened the pipe leading into the resonator) This of course makes my problems with the product more complex. The installer made the fitment without my knowledge, however the product should have never required specialized fitment. My complaints:
The exhaust has signifiant drone and reverberation, it is not fine for daily driving as advertised by Vivid Racing.
Additional cost I incurred for installation, an additional 1.5 hours of shop labor time.
I contacted Dan Mermelstein from Vivid Racing who was very unhelpful and shrugged the issue off, stating I received a discount on the exhaust (apparently discounts mean no customer service) and that the exhaust is modified and no longer his problem. This is their problem as their sales rep stated it fits Gen II cars when in fact it does not. The exhaust was incorectly advertised and therefore certainly Vivid Racings problem.
Further research shows that Vivid Racing and Agency Power are the same company. Under no circumstance should this exhaust have been sold to a 987 Gen II owner when Agency Power had never even tested the product on the vehicle. I am very displeased with the customer service and how the issue has been handled by both companies.
I would recommend anyone considering purchasing from Vivid Racing make your decision carefully as they will not provide you acceptable service if you have issues with their products.
