Thread: ZZP sucks SD headers?????

I've been having great success with zzp customer service over the last 2 years. Can't complain

Regarding the SD headers. I still have the original single wall flex for close to 5 years now. Still doesn't leak.

As for ZZP customer service. I've had some good and bad since I've been dealing with them since 01-02. No company can be 100% perfect.
