Everytime I have installed a performance exhaust systems on my vehicles, I lose performance - mainly low end torque, throttle response and drivability. No one drives around at 5,000 RPM, and this is where the performance is noticed most.
I need an exhaust system that will increase performance without losing my low end torque. The engine in the Hummer is desgned to provide maximum torque at low RPMs to get this heavy vehicle moving.
I have tried differnt brands on every vehicle that I have had and they all do the same thing. I am fed up.
I odered the Corsa Touring series thinking this will add some additional back pressure over this current Gibson exhaust system.
I regret ever removing my stock exhaust as this thing is very sluggish down in the low RPM ranges since I removed the stock exhaust.
Any ideas guys? I am so tired of this marketing crap. All of their dyno charts so gains about 3200 RPM+, but we normally drive much lower than this. </div></BLOCKQUOTE>
That is why I am only replacing mufflers this time... not entire systems/catbacks.
Usually I install anything from long tubes to cat backs... I don't want to lose any low end so a muffler is what is going on this time.
