Re: Problems with LET
I ordered my SL55 intake, plugs and 185mm Pulley from LET on the same day.
Granted - I was one of the first to order from LET but I received the AMG Intake and Plugs in two weeks. The Pulley took 12 weeks. This seems to be the norm for all of the "built-to order" vendors on this site.
I'm sure the headers will take some time - but you will be one of the firsts (that I know of) to install a set of headers.
Please take pictures and provide a write up letting us know how the installation went, sound, etc..
I also hope you can run a before and after dyno.
