Turbo Corvair Muffler Article

[PxTx]

Thanks for the info guys. I am still helping my sister Monica with her Nova and we are trying to decide on the mufflers. She is running a 67 L88 and our goal is to keep it correct to the period- sound an all.

My pop felt the Corvair mufflers would perform well as he put them on his 67 Chevy II back in 1971, and they are still on it today! He said he chose the Corvair mufflers after reading a magazine article from the 60's. Gosh knows the one he is talking about couldn't have been the one from the 80's since the car is still unmolested from '71!

My other sister has a modern transverse muffler on her 69 Camaro. Although it hardly makes a difference in performance, it definitely has a newer sound.

Does anyone know what type of performance mufflers were available through GM in 69?

Thanks,

Paul III

This is only semi-relavant, as I'm not familiar with the Crovair muffler in quesiton, but here is THE BEST exhaust article I have read: EXHAUST TEST

It found that the DynoMax mufflers performed the best overall, which is good, as we have been running DynoMax products on all of our cars, and are fixing to add another to the Camaro. In fact, DynoMax mufflers are recommended by Bob/Dan at the Pure Stock races. I think CopoPete has a DynoMax transverse on his white COPO (that runs low 12s!)...he seems to like it, and I can honestly say it sounds AWESOME!

Thanks Chevy454

I am having exhaust put on my car this week and that article clears up a few things for me,especially about the crossover type and size I am going to use.

Thanks

Around here, the Turbo Corvair muffler was a very common "performance" muffler in the 60's and early 70's. Hands down, it seems to have been the muffler of choice in a small pole I took locally.

Please, anyone who actually changed some of the equipment on their cars in the late 60's let me know what mufflers you preferred then. I'm sure the has to be a few guys here that were actual gear heads in the Muscle Car Era, where are you?
