"Installed on a V 10. They were a bear for my mechanic to get the old ones off and get the new ones on. Very tight fit be prepared to disassemble alot around wheel wells. They is very little sound difference, appearence is great, performance when towing was improved, will see how much improvement on the beach."

"Outstanding constrouction fit and finish. Instalation instructions and hardware are great with nothing missed. When I learn to keep my foot of the Power fun meter I hope to see some milage improvement. Big inprovement in everyday driveability and power. spend the extra and get the ceramic coating well worth the extra cost."

Great Torque Header

"The Doug Thorley header ads some extra MPH to the top end of my powerband,but where i notice the most difference is the torque it puts out coming through the gears.With brand new 31" BF Goodrich All Terrains,she lays down the rubber much easier now.It sounds much better too."

Great fit, a little tough to get to plugs

"THese things fit great on my 1st gen camaro w/ small block. Geat clearance to PS box and tuck up really tight at the collector. Only complaint would be that it's pretty tough to get to the spark plugs (had stock manifolds on before) -- need to use box wrench on several, but I'm told this is pretty much standard practice with most headers anyway"

"Some of the chrome was chipped off. There is nothing under the Doug Thorley emblem and is prone to rust. Header flange is not milled as nice as I expected. Overall could have been constructed with more quality."

"2003 5.7L Dodge Ram 1500 4X4. Took longer to get the stock exhaust off than it did to put these on. Bolted right up without any problems. Gaskets are good quality and thick. Not like the cheap paper thin ones you get from other places. Truck is much more responsive and quicker off the line from idle. MPG hasn't changed but, what do you expect for a 5,600 lb V-8 truck? AutoAnything had them to my door a week after I ordered them, thanks."

"When it comes to headers, Doug Thorley beats all others hands down. The quality of workmanship is flawless. When I ordered them I expected to have to go out and buy extra parts such as bolts, gaskets etc to completer the installation. NOT SO! They come with everthing you need, along with easy to read instructions for a painless installation. I highly recommend that if you are considering new exhaust components, look at Doug Thorley first."

"Fit and finish was perfect. Hardware for install was changed to stainless because I ordered ceramic coating and did not want to see rust on hardware. I also used copper gaskets from header to head to prevent gasket blowout. A big change in power in pulling range as well as improved fuel mileage. Very happy with overall purchase."

"These headers really helped wake up the bottom end of my truck. Construction and finish are excellent. These are probably the best header out there for a 4x4 truck that needs all the low end torque they can get. The 310Y is a long tube headers and gives you the best power band, better than the newer midlength model."
