Can somebody please tell me the collector diameter on the Dynomax small block headers? I'm about to start gathering parts for the next project. Thanks!
Thank you 79er. Your answer saved me from buying 3 1/2 inch reducers and finding out that I didn't need them. I'm going to use the extended reducers from Jeg's. Having the size reduce down in 2 inches sounds like it would be more restrictive than reducing in 6 or so inches. I might even get excited and have the muffler shop run 3 inch pipes from the header through the crossmember before reducing it.
If you read that I'm running ten second E.T.s at 140 MPH with my mostly stock L-48 you will know what my secret is. More likely 14's with a reaction time equal to my E.T.
