do you have stock manifolds? if so, any of them will be better. Eddie Marine, stainless marine, CMI, etc. etc.

Search for exhaust here using the search function. everyone has an opinion.

My opinion is if you aren't going to go for headers like CMI, get the best deal you can. they are all pretty much the same.

Hardin Marine has some good ones as well. CP Performance sells them. Bought a pair for my Blackwidow.

I had Dana's on my 27ZX. Good bling for the buck.

Stainless Marine makes a nice product too.

i went with stainless marine there excellent quality and sound thanks stainless marine
