Customers consistently praise the product for its excellent fit, great quality, and budget-friendly price.

Customers appreciate their old-school design, as they are used to uphold period standards in car builds. Users also note the practicality and convenience of the product, considering them a go-to item that fits their needs better than more modern, local parts.

I use these flanges when making split exhaust manifolds for inline six cylinder engines. They're much cheaper than what's available from the local parts stores, but of equal quality.

Would Recommend

Nice parts, reasonable price

There are many newer, more modern options for exhaust system connections available today but my cars are built to period standards and those modern parts just don't look right. These flanges are just like a guy would use back in the old days. I'm glad they are still available through Speedway, most of our muffler shops don't carry these any more.

Would Recommend

Worked great both times purchased.

Needed to flange a 2" to 1 3/4" exhaust. Made my own for the smaller pipe but couldn't beat having the 2" readymade.

Would Recommend

Just what I was looking for.
