Yesterday I had a Redback 2.5" cat back system installed on my VS V6. Prior to this I had no issues on acceleration.
After the install, the car will drive fine under 'normal' suburban driving, using smooth acceleration. However when I go to accelerate hard, such as entering the freeway, overtaking, or 'spirited' acceleration for the fun of it, the engine stumbles and farts until I back off a bit.
Plugs and leads were replaced in the last month, air filter cleaned. Doesn't sound like any kind of leak from exhaust system.
Other than the new exhaust setup, no other changes - engine stock as a rock.
Any thoughts based on the above it could be?
