so ngam talk about exhaust I just wanted to share my experience on running my aftermarket Gen2 high flow muffler for the pass months


I've been running this Gen2 muffler for few months already (actually forgotten how long) It's a S-Flow unit for Gen2 but it fit my gaga as well just need to make some welding changes on the inlet and the mounting points.

Muffler Spec
2inch inlet
3 inch muffler outlet
For: Gen2
Company: Pro1
Type: Cross-flow

This muffler when newly fitted is very quiet and gives a subtle sound good for those looking for something less attention grabbing and potential problems from authority. Muffler construction quality is quite good. After all the glass fiber burn in the sound decibel only increase by less than 10% (assuming) and still have an acceptable sound level.

Currently after being using it the idling sound is a bit louder than new but it's gives a nice deep growling sound at idle and a deep solid punchy sound when the throttle is apply while driving. Even at WOT the sounds is still solid and not noisy at all. Performance wise, I feel the car is pulling stronger through out the usable power band. David drove the car when I fitted this muffler and he fell in love with it. Price wise it's not expensive so I recommend this muffler to gaga owners who is looking to change their muffler but still up to personal preferences.

Thank you
