LV Corsa S Slip on

Just what I was looking for. Not much louder than stock but noticeably deeper and just better sounding. It comes alive when accelerating and revving hard but just step up in being more aggressive sounding than stock

Shopping with Bills has been an excellent experience

Shopping with Bills has been an excellent experience. They have been fully transparent about my expected delivery time.
Notifying me right away that my Arrow exhaust comes from a warehouse in Italy and I can expect a 2-3 week delivery time due to this.
There was a day delay from DHL to ship Bills the item and they even gave me that separate tracking number. Was shipped out promptly after Bills received it and UPS delivered a few days after.
I received updates on every movement and it was very much appreciated.
No other company I have shopped with has done this.

I highly recommend purchasing from Bills!

It's beautiful, quiet, lovely sound.

It's beautiful, sleek, weighs half the stock muffler. And it has a wonderful much quieter sound than stock.
I love it!
