Title: Quick Header Question?
Post by: Asbury030 on August 28, 2010, 04:19:19 PM

So is there any difference between the Doug Thorley and the Calmini header? If so what are they?

Design for both is different, collecter styles, length of tubing, finishes, and the 8v and 16v headers are two completely different animals , so you can't compare them. Does Thorley make a header for the 16v?

I'm pretty sure my Thorley header is the ONLY 50-state emissions legal header for the 8v.  Someone correct me if I'm wrong but I don't think any others are 50-state compliant.
Calmini's looks the same so you may be able to "fool" a smog tech if you provided the E.O. # from the Thorley header.

Honestly, neither of these is much of a deal compared to the stock unit.  The stock 8V cast-iron header is a really nice 4-into-2 unit with a 2" outlet that cleans up nice and lasts forever.  The after-market tubing headers don't add anything & are just a joke.
