[Mr Skrunts]

A lot of the Yank V8 have a balance pipe from the left to right exhaust pipes.  Does it make a difference, if so would it make a difference on an aftermrket cat back stainless system.?

TIA

They have a balance pipe because they run 2 seperate exhaust setups.

It dodes benfit the setup in 2 ways,

1) It makes it sound better (rather than alternating pops from 2 exhausts!)

2) It helps torque by aiding the scavenging affect and gives  theoreticaly less restrictive exhaust setup

So that being the case and the Miggy V6 only shares the rear tail, would the Migs benefit from a Balance pipe.?

Only if they had seperate tailpipes, they balance themselves in the rear box section. Personally I'd fit the balance pipe and seperate the tails

The balance pipe has to be much closer than the tailpipe to have any effect on engine output. Normally they run across the bottom of the bellhousing. It also depends on firing order and I wonder if it'd be any use on an engine that has such a poor exhaust manifold in the first place.

Off to read that chapter of my tuning book when I get home.

The book being this, by the way:

http://www.amazon.co.uk/Four-stroke-Performance-Tuning-Graham-Bell/dp/1859604358

... although I certainly didn't pay that much for it new.
Everything you ever wanted to know about tuning naturally aspirated engines.

I just post on here when I have a question, tis a lot quicker than me reading a book. :-/
