Now...I know I'm old school (70's), but what's up with all the new exhaust technology? Long tube, shorties, equal vs. unequal, H vs. X pipes.....sheesh!!!
What's wrong with a set of long pipe headers and running straight exhust tubes through some flowmaster mufflers?
Am I missing something here? Is there someplace on the internet where I can go to learn about all of this?
Thanks in advance to the list.
H pipes have been around since the 60's. It helps to balance the exhaust flow and gives you a little more power at the top end. An X pipe is a modification of this that improves flow, and moves the power band down a little. As for headers, Carroll used Tri-Y's for a reason. And it's still a good reason. As a general rule, long tubes give you power at thetop, short tubes power at the bottom. Tri-Y's give you a little of both. For low cost and good power, use a set of Tri-Y's, straight pipes to the mufflers, and out the back. The little bit you give up for not having an H or X pipe just isn't enough to worry about for a street car.
I think you have this reversed a bit. H-pipes appeared on production hi-po cars to boost low end and quiet things down, a job previously assigned to resonators. The X's are most efficient at high rpm, which is why every Nascar ride has one.
Personally, I much prefer the lower tones associated with H's and Walker mufflers, but I'm a bit of a traditionalist.
True, the tri's are a good compromise.
Any shop building a fresh exhaust can whip an H into it for not much more.
