Almost all exhaust suggestions are super loud. Borla Pro-XS middle muffler + vibrant rear muffler is a good/classic combo.

I have a resonator delete and Magnaflow mufflers. The drone is there at highway speeds, but not intolerable IMO. The acceleration sounds great.

Pros: acceleration sounds great

On my eclipse gs sport I've put in a racing header and cold air intake, (although my tuner said the stock intake is actually better than any aftermarket stuff because of where the breather is located). I also had a custom exhaust made with magnaflow mufflers.

Pros: racing header installed
Cons: stock intake better
Vehicle: Mitsubishi Eclipse

Got the tires installed today and what a difference some fresh rubber and suspension makes. Now onward to a less droney muffler. Magnaflow sounds great but that drone is unbearable.

Pros: fresh rubber, suspension makes difference
Cons: unbearable drone

I definitely have an exhaust leak coming from the seam on the muffler where the sheet metal is wrapped around and overlaps itself. The exhaust in question is the magnaflow catback specifically for the MKIV R32.

Cons: exhaust leak
Vehicle: Volkswagen
