M4x4 your crossover looks more like a siamese than a true X, ? i spent some time listening to mfg's sound clips and comments on flow performance as well as some tuners claims on exhaust. I have this comment; Yes a true xpipe can increase scavenging resulting in increased flow rate in some engines over an H, which would clearly provide for an increase in top end HP in some engines. But additional notes would apply. As mentioned here already the X is much more difficult to weld/install in rear drive cars for mfg's (or for owners) than an H. Also as mentioned here the X produces a BIG change in the sound of the engine, which is a visceral experience all of us consider when tuning our exhaust. Finally, the H does a very good job in smoothing the exhaust pulses in the Ford v8's and also produces an increase in performance over independent dual exhaust systems. So for all the reasons mentioned above IMO you really gotta love the raspy flowmaster sound to bother with an X. thanks.
Well, crap - let me run right out and get a proper 'H-pipe' because someone on the internet says so.
Look - I bought the Pypes kit because it was recommended by a friend who'd installed one on his '68 Mustang - I wanted a kit I could simply install and move onto another part of my project. Pypes calls the junction between left and right exhaust pipes an "X-pipe." Forgive me for doubting your reasoning, but I'm going to take the side of a reputable company that builds exhaust systems - if they call their product an "X-pipe," it's an "X-pipe." THAT, is all I need to know.
I also honestly had no idea how my car was going to sound when I bought the system, as the car was not running when I bought it (engine seized, among other things). When I first fired it up and heard it for the first time, I was VERY pleased and not only happy it was running, I also enjoyed the sound coming from the back of the car.
My only purpose for input in this thread is to share what I went with and what I know to be true: the Pypes Street Pro X-pipe kit is complete, easy to install, and works perfectly... it also looks great, is of good quality, and has a good exhaust note. I happened to have pictures and a brief video - so I shared. That's it. I'm not a Pypes salesman, an expert on their products, nor am I claiming it to be anything it is not. Just sharing what I have for someone else to make a somewhat informed decision for their cars.
If I'm reading things wrong, and someone gets their feelings hurt over my words, I'll apologize now - I'm already having "a day," and not looking to get into a pissing match over what
is or
is not best for my car based on someone else's opinion.
