"i had to buy better gasketsthe ones that came were cheaply made and would not seal.The sound is annoying alsothe car has a low growl sound now and did not before.If i had known this i would have paid the 250.00 instead of the 170.00 and received a better quality part.thats what i get trying to be frugal(cheap)." posted by: bubbajay405 on July 11, 2013 view all 2 reviews
