    Thinking of getting ebay m20 headers

    Anybody have a sound clip or thoughts on what the ebay "long" tube headers to a single 3" cat and 3" cat back would sound like?

    The 3" single was put on by the OP seems almost too big to me, It's already pretty loud but I am sooo tempted to buy a set of those headers.

    The car already has a cam no head work, markd 19lb and m30 afm about to go in. Not that that makes much difference to the sound other than the cam but as far as how much exhaust is too much isn't a 3" a bit much?

      You don't want to go single pipe with these at any rate (if we are talking about the Free Chinese / Kamotors ones).

      They do sound wicked done right.

        Why not single pipe does it make it sound bad? Pardon my ignorance I really don't know much about exhausts, oh and yes those are the ones I'm talking about

          They were originally designed for twin pipes and work best that way.

            Yah I guess that's why they have a x-pipe built in eh lol, but if I was to use these with the existing 3" cat and 3" single back what do you think it would sound like?

              I used them with twin exhaust, no cats, and it came out sounding awesome. Fitment is a huge pain in the balls however. They just don't snug up well at all, I ended up having to bring mine to a shop and they had to do a shitload of work to get them to seal up.

                      chinese headers are hit and miss...some suppliers (ebay retailers) have batches of good ones, some don't.
