Value of Midpipe

So the 3.8 mustang having the even firing engine a mid pipe shouldnt boost hp at all. So my question is why do so many people spend the extra money for the X or H pipe if its not adding anything, is it just sound? I'm starting to piece together my exaust system and i dont know if i wanna go straigh duals.

Any opinions?

Actually, it helps balance the pressure and helps with scavenging. You're not gonna get huge gains from this, but every little bit helps.

Traditionally the X helps up top and is more raspy, and the H helps down low and has a deeper sound- I would think it'd be similar on the 6 as well

It is the same!.. Just your gains won't be as good do to the smaller displacement!.. But the exhaust still works the same!...

I have an extreme setup. I used to have an O/R H-pipe. Now i have a hi-flow catted x-pipe. Much better sound. Plus I have a radical cam compared to most, so that helps alot. I have a 224/230 cam if you are wondering. Very lopey and deep. Plus i have some flowmaster 40s on my setup as well.

Re: Value of Midpipe

being an even fire motor, is there really an issue with balancing or just not as bad as an odd fire car?

I would assume its mostly due to the design, not because its needed... you just expect to see a balance pipe so you get one.

Re: Value of Midpipe

You are correct, it's almost a non-issue with the balancing. But as I said before, every little bit helps. The main benefit comes from the scavenging reducing the pressure and strain on getting that exhaust out of the chamber which is why equal length long/short tube headers work so well. They provide a constant equal "vaccum" on the exhaust to suck the air out of the chamber

Re: Value of Midpipe

Hmm, for 1 or 2 horses i'll probaly just skip the midpipe. Someone was tellling me that the i should go 2.5 piping instead of 2.25 cus the 2.5 will be louder, any truth to that?

That is a very weird order

---------- Post added at 12:21 AM ---------- Previous post was at 12:19 AM ----------

Why would that effect the noise of the exhaust though?
