Customer Reviews

Now for the Billy Boat review... The exhaust is fantastic. Looks wise it is very sporty and in my opinion looks much better than the quad tips on the avant (I think the quads looks better on the sedan though). But the most important part is NO DRONE. The sound might actually be too quiet for some, it makes the car's engine sound deeper with no downshift turbo "fart".
