Stock 340 Manifolds or TTI Shorties?

Many people are stuck in the 70's with their idea of low hanging, leaking, poor fitting headers. My TTI W2 headers fit great, and yes a 4 speed car. Been on 5 years, never had a leak. I think people get caught up in repeating something they heard until the point it becomes gospel. The new TTI, and Doug's headers are great. This is a general statement and directed at nobody in this thread.


I would run manifolds before TTI headers. It’s that simple. IMO they are junk and there are better options. If you are smashing your headers flat it’s because you have issues driving the car with headers.
