will it work on my lb7 what kind of power will it add and how much mpg will it add

[Meyerperformance]

You wont see any noticeable increase in power, mileage will be minimal to

[bigfatbulldog]

will it sound better

[K9Duramax]

Have any Cat back systems on sale? Looking for 4". Thanks.

[Meyerperformance]

yes it will sound better

[DSTRBD]

Radar- Just sent a PM back, thanks!

bigfatbulldog- Yes, there is a slight power increase (10-20hp depending on the dyno). Backpressure is cut down increasing the efficiency of the engine. Mileage increases are minimal (.5-1.5 mpg) with this mod alone though. The sound is definately impoved.

K9Duramax- Yes, do you want a tip with it?

[Meyerperformance]

have you seen an actual dyno to see power increase, because i dont believe an exhaust alone will do anything, it with fueling and more air will show increase. But i dont believe it alone is worth to buy for power only. Sound and better engine efficency yes.

[4x4Fantasy]

Anything that increases the engine's efficiency results in more power. The motor isnt making any more power, but with more efficiency, the tires see more power. Drivetrain loss is a killer, as is intake and exhaust restriction.

[DSTRBD]

Yes, I have seen several dyno sheets with the results. An exhaust alone on an LB7 is NOT a good source of power, but it definately will cool down your EGTs and improve the efficiency of your engine.

and with lower EGT temps, you can run a higher level on your programmer (assuming your trans can take the power increase).
