Notorious | Anyone ever heard of Doug Thorley headers for an L98 C4? | ||
Elite Guru

They're not made anymore and I don't know how long it's been since they were made, but I recently acquired a set. They have never been used and are of extremely heavy construction. A friend of mine has some EM headers. He said they weigh 10 lbs. a piece. By comparison, these weigh 18 lbs. per. They appear to have longer primaries than any other header I've seen for the C4 with the possible exception of LPEs, which might be close. They also seem to be pretty close to equal length which is also something that most C4 headers I've seen don't offer. Even though I've already got nice headers on my LT1, I'm tempted to give these a try. They have the L98 a.i.r. hookups but I can plug them, I don't use them anyway. I'm just curious if anyone's ever heard of these, used them or knows anymore about them. I thought I knew of every full length header ever made for these cars but I guess I didn't. BTW, they have 1 5/8" primaries which I also like.

I didn't know Doug Thorley made C4 headers...I checked before I went with Hooker 2151's. Are these Tri-Y by any chance? ...or 4-into-1?

Quote: I know the name, don't know their quality. They are of very high quality. 3/8" flanges, very heavy gauge pipes, etc. The only thing that is not to my preference is that they are nickle-chrome plated. I would much prefer that they were coated or even better, stainless steel. |

Doug Thorley's have always been a premium header. You are lucky to have a new set.

Still around, but too bad they aren't tri-Y design. those babies are really good for low end torque.

Yup Case, what brand are those? Back when I was a kid, the tri-y's were the way to go for the low end torque. They lack a bit in the higher RPM range but most people who drive on the street don't use that part of the RPM range as much anyway. The only problem I see with your tri-y's is that I'm not sure if there are provisions for cats. Do you have those on your 94, Case?

These are custom made for a right hand drive C4 mate. Have a look in these pics, which will answer your question about cats. I wouldnt run without them, cause its plain stupid and you lose torque.
