SLP Headers
Does anyone have any direct experience with SLP headers? I'm interested in performance results gained, fit, finish etc. They are being recommended to me by a local Chevy dealer speed shop, Tom Henry Racing. Thanks for any info.

Don't know about their Corvette products, but their F-Body headers do not have a good rep, and neither does their customer service in general. I know several local shops & tuners who used to carry their merchandise, but dropped them because of various problems.

No offense Dashti, but SLP headers are the worst. I've been dealing with American Racing Headers 
, they have proven to make the most Hp gains, best customer service, and they install the easiest out of all that I have dealt with for any type of car.

I don't think any are CARB approved. Callaway said they haven't even started the process yet. They say they will be approved by the time California owners need their first smog check.
