I just bolted on a Bassani Cat-Back and I must say that I love it. It has a nice sound to it and it has a great fit. I had a Borla on and it did not fit properly. The tips were dropped down below the little cut out slot for them.

Well guys, I was considering a set of headers. Which are the best? Do I have to get Bassani headers since I have the Bassani Cat-Back? Are they the best? Will other headers bolt on to a Bassani Cat-Back Is there a difference in sound between different headers? Please help me out here. Thanks alot!

 

IMO stay away from shorties.

 

Also, Is there a big power gain with headers?

 

Gain, yes.

Big gain - depends on who you talk to and what mods they have. With LT's we have dynos that show 20hp+ gains and some that only show 5hp across the chart.

 

The REM lontube header kit with high flow cats will bolt right up to your catback, as long as the catback was made to bolt into the OE midpipe seperation. All hardware, including O2 extenders, clamps, and HP exhaust gaskets are included in the kit. It's also entirely made of 304 stainless. Others aren't.

Gains will vary depending on what else you have done to your vehicle.

 

Look at this thread for my gains. If you go to the second page, the dyno charts are there. IMO the sound of the JDM/Kooks alone is enough to buy the exhaust.
