Yes, 1977 light trucks are factory equipped with catalytic converters.
YES it did.
No, the first catalytic converters installed on GM vehicles was in 1975.
Catalytic converters are part of the exhaust system under the vehicle. They are right after the exhaust pipes come down from the engine
2004 Chevy Blazer has two catalytic converters. One up close to the engine just after the pipes from the exhaust manifolds come together, and one down closer to the middle of the vehicle. The first one is sort of round, and the second is more flat and wide.
Yes
They where required for the 1975 model year.
One two
Direct to fit Catalytic Converters come ready to install with all parts pre-welded. These are better for the DIY professional. Universal converters are cheaper, but require cutting, welding, etc. These installations are best left for the shop professionals.
Yes
from what ive learned most 1993 models come with 4, as well as the crown vic and mercury sedans. at least thats what ive come to find out
It sure did, That is the law on all makes and models.
The 1977 Chevy Nova came with an inline 6 and a V8. They did not come with a V6. If a V6 has been installed you need to know which one as the chevy engines have very different firing orders.
