1969 BB EXHAUST QUESTION

[Marc N.]

first....happy holidays to all..........happy new year!

on my 69 bb 390hp vette, I find that the stock exhaust pipes are really narrow....it is amazing that gm made them this way on a bb...anyway, I have a set of off-road under the car exhaust system (like the side pipe system but that they now offer for under the car) from a 67 427 new. will these fit on a 69 under the car???? advise and thanks

They will fit with slight modifications as long as your car is a 4 speed. They will not fit around left? side of the automatic. You will need to flatten them where they run under the rear axle. On some cars you will need to dimple them for clearance, most do not require this. Sounds wonderful and will make a noticeable difference in performance

ALL 1969 Corvettes, from base engine to ZL-1, originally used 2" exhaust systems.

The 2-1/2" 1967 system will fit your car as Dick described will fit your 1969. However, the muffler brackets are different for C2 and C3 cars. You will need to change the muffler brackets (i.e. weld on new ones) or use the 1973 muffler hangers. The 73 muffler hangers will allow the installation of mufflers with C2 brackets on C3 cars.
