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

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

bigfatbulldog · 05-16-2008, 11:58 PM

will it sound better

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

**Meyerperformance** · 05-17-2008, 11:18 AM

yes it will sound better

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?

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.

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.

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).
