What headers work, and what don't?

There's a huge difference between TTI's and regular shelf headers but it mainly comes down to your priorities- I always build my junk on a budget- tight one at that so I'll run the $159 hookers and find a better place to spend the other $600.

We put TTI's on my buddys Dad's car but he has a larger budget - my car has a stock block iron head small block with an 833, his car has an X block 422 with indybrocks and a Passon 18 spline 833 with a gear vendors hanging off the back so spending $1300 on headers and exhaust isn't a big part of the budget.

Driving habit has a lot to do with tearing up the cheap headers, you have to watch potholes, dips in the road, entrances to parking lots/driveways etc, with my last Duster I drove it for 3 years and never scraped them, the guy I sold it to ripped the 2 bottom tubes open the first night he had it.
