Phenomenal quality was my initial impression. I was surprised at how much their fiber glass material dampened the sound. It's practically straight piped with long tube headers, but not obnoxiously loud. These are definitely the heaviest mufflers/glasspacks I've ever held. Might want to take this into consideration for racing, but overall would 100% buy again.

Great muffler, anything by thrush is really good and usually worth its money. Very easy to install just clamp on or weld or both. But it is very loud so if loud isn't for you then this isn't your muffler.

Make sure you weld them on. If you use clampsthey will fall off. Great rolling thunder noise. More HP.

La peinture n'est pas conçue pour la chaleur.. je dois tout meule, peinturé ça avec de la peinture haute température... La longueur n'est pas 29" mais bien 25" et en plus les soudures sont vraiment de mauvaise qualité.. je suis soudeur de métier et je vous garanti que le chaud et le froid vont craqué les soudures dans pas longtemps... Déçu
