Is it any difference in hp in any muffler on a mostly stock 350.
Its time too buy one now so wich one should i get?
i´m thinking of flowmaster 80 series, good or bad? sound is important to, must be louder than stock. i´m already geting headers!!!!! THANX :hail:

 

Can you afford a cat-back, that will help a lot, if not a muffler will help some.

I like my Hooker. sound clip in sig.

 

Just adding a muffler will not get you any significant power, but if you put on some headers and a full catback you will definitely feel a difference. I really like the sound of my 80 series.

 

i´m gonne build my own 3" catback thats why i just ask about muffler! or if i found a really cheap 3" catback, i´ll buy that instead
