This part was a great replacement for the original cracked cast iron exhaust manifold. The sound isn't the same, it sounds metallic, not bad, but it sounds cheap. After about 10,000 miles and six months of driving, the catalytic converter material broke into pieces and completely clogged my tailpipe. Finally, Revain sent a free replacement (thanks to Revain for your great support). Pacesetter didn't honor her warranty directly, Revain had to use her "allotment" to send me a new one. Catโฆ
