Arrow Sperry Exhaust Header for 105 series

Am interested in buying a used Mike Sperry 4 into 1 tube header for 105 series cars. Mike had them made for several years.

Thanks.

I had one on the GTV, but it left when the car moved east.

Do you remember if the collector box was under the floor?

I don't recall. I couldn't find a picture to verify, but I don't think the collector section was vary long.

There was also a rumor going around a while back, that someone in the LA area has the patterns for the Sperry headers.

You should ask Brad at AR Ricambi if he has the patterns.

Can't think of his name right now. But I believe the guy who bought the Sperry fixtures is the same guy advertising complete race engines in the recent Alfa Owners. On the Alfa race group he goes by "177hpatthewheels", or something like that. If you can't find his contact info, let me know and I will try to look it up.

Thanks, but I already have a set of custom tubes. I want to make a nice "correct" compact set of stainless tubes that fit a range of 105's and at a price that everyone can afford (like Mike Sperry's). I don't think many folks are interested in buying a set of stainless tubes for $2000.00, do you? Not to mention having tubes running all over the place like these.

Yes, because they wouldn't fit in a car with floor pedals.

Nice looking headers, but not an Alfa . . . what does it fit?

sperry headers where a bit more in cost than the centerline and IAP due to "bundle of snakes" constrution with more weld tube sections.

jake and i took the original sperry jigs down to fabricator to see what it will cost to weld up a dozen or so batch in both mild steel (durability) and stainless (appearance). the cost was significant like $1300 - $1000 if i remember correctly.

i think those are alfa nord headers in the pic but with the less than ideal perpendicular flanges not matching the ports in the head. They sure look fantastic though especially with the flared collector pipe in the end.

Actually the tubes fit in the Duetto quite nicely or maybe not so nicely depending on your point of view??? The megaphone merge collector is custom designed and constructed by Burns Stainless Steel exactly for my engine configuration (see bottom photo). Notice the length and the beautiful TIG welds (Burns signature).

Regarding the exit angle, the photo is the bottom view of the header and while the tubes don't exactly match the port angle it's closer than it looks. As I recall Mike's tubes are a little off as well. Believe me it's amazing the fabricator could get it all in the space and have the correct length step primary tubes enter the collector in the correct order, the burns collector is really loooooong and it doesn't go under the car. The Duetto is a 67 and has a petal box, i.e. no room for the collector. I had to have the entire final assembly ceramic coated to keep the temperature down with the tubes running so high in the engine compartment.

Happy Motoring.
