Just installed full turbo catback. It’s a terrific system, good power boost through the rev range, surprising (>5% fuel economy increase), and the sound, which I found overpowering at first, has settled down to a lovely note after a few hundred miles’ “spirited” driving.
My one quibble: The exhaust tips, which look fine in photos, but seem almost cartoonish in real life: They’re just too big and “trumpety.” On a Golt, they look like aftermarket bling, at least to my eyes.
Presumably, they’re easiy swapped out with something a bit less outré.
