OMFG, not another h-pipe thread!

I was at a muffler shop and the guy was asking a lot of specific questions. Would there be anything wrong with making a really simple h-pipe like shown in the attachment?

I think a lot of muffler shops do exactly that when they're fabbing up the driver side pipes.

 

besides the fact itd be fugly, and it wouldnt detach unless he made it in a coulple pieces (for removin midpipes), and itd have uneven lengths on either side.....

I would never do it like that. If anything, cut the whole Ypipe out after the cat, and at least make things even.

 

So I'll ask the guy to just cut the whole Ypipe out after the cats, and make both the right and left pipes from scratch? Is that what most of you are doing? Is there any reason to try and salvage some of that passenger-side pipe?

BTW, what is a midpipe? Is this what's between the cats and the muffler?

There four types of mid pipes - a Y-pipe, an H-pipe, X-pipe, and true dual pipes. The Y-pipe has a Y-shaped crossover between the left and right exhuast banks that joins them into one pipe for exiting. The H-pipe has an H-shaped crossover between the left and right exhaust banks that equals out the exhaust gases on each side and allows for a dual flowing exhaust. An H-pipe will give you a low tone, and the H-pipe sounds best with a chambered muffler. The X-pipe has an X-shaped crossover between the left and right exhaust banks that equals out the exhaust gases on each side and allows for a dual flowing exhaust. An X-pipe will flow better than an H-pipe, but give a more raspy tone. The X-pipe sounds best with a straight-through muffler. The true dual design has no crossover pipe to equal out exhuast gases from the left and right bank.

It is generally agreed that with the Even-fire characteristics of our V6 engine, a crossover midpipe is not necessary but each type will produce a different tone. If exhaust tone is important to you, for the cost it is worth having your muffler shop fab one up. I've heard it might only cost about $20 extra. I have true duals on my car and I'm happy with the tone.
