I was going to do an X-pipe, however I still have a mostly stock engine, so the H pipe worked great for me, I have no for sure info on the X-pipe, but why not go for it?

Hi. is there a way to get this sound without the split headers? I have a 67 stock inline 6. I went to the clifford performance site for the parts but i didnt see the "H-pipe." was this fabricated at the muffler shop or is this something Flowmaster makes?

@mustangcraft We Fab'ed the H pipe up in the shop. I'm sure the it would sound like this, but not as aggressive, try looking up an I6 200 + flowmaster 40 series, the falcon 200 6's all had the same headers I believe.

I'm sorry I cannot give you a strait answer, because I do not have the computer software with me to do a flow analysis.

Good luck!

I use an H-Pipe, Because my exhaust is 2.25" diameter tubing, which is rated for about 200-300hp (duals). The H-pipe effects the flow enough to the point where its not a rattle sound or ricer sound, it gives it the low tone. An X-Pipe would make it quieter than true duals, but the H-pipe on an inline 6 with split headers and you will not be disappointed. Plus one day I want to apply a bolt on supercharger, which will get me around 200hp (total).

My exhaust is AL-409 stainless steel also.

@kingcollegefan I used Clifford Performance for the split headers & flow master 40 series. On the inline 6 (64-68) the 3rd & 4th ports are not separated so you will need to also buy/find the port separator ($10) and have it welded in, because other wise it would sound horrible. I made this mistake at first. For about a month it sounded like an inline 4 with strait pipes... kinda embarrassing.

Thank you for the info. I ended up getting the headers just need to figure out how to fab an h pipe. Do you think an x pipe would give it an aggressive sound? My whole purpose for wanting to do this is because I don't want the ricer sound neither do I want it to sound like a bus. Lol.

I like it :)

This sounds like a v8

[WWFstunna13]

do you have an H-pipe?, a X-pipe?, or true duals with flowmaster 40's??
