You lose low end torque when you go catless. Not as much back pressure.

yea....the ticking is getting to me...and the smell of unburnt gasses in my cab starts to give me headaches when im sitting at at stop light...(windows are always down...)

and as for the loud ness..its supposed to be like that..you just elminated 4 cats...so its bassically saying u eliminated 4 mufflers....if u wanna make it a lil less raspy get some long tubes..some say it makes it more smooth...

discribe the sound ur talking about more...cause im confused....as to the swooshing sound..it from the fact that you dont have cats....


and yes i did notice the lessened acceleration...its from the x pipe...it takes some low end tq and adds some high end HP

ive been running like this since may 22 cause i hadnt had the time to get under it again since school and work

if badfish pops his nose here he can tell you for sure...he has the same setup as you

Alright hold up a second. Quick question so I understand what you guys are talking about. Did you pull out the reducer inside the stock H pipe and put that in the driverside pipe of the X and then bolt it back up or did you just drop the H and bolt the X straight up?

As was said earlier, less back pressure is causing your acceleration to drop on take offs. When you are high up in the gears though, your top end picks up like crazy. When you add, you lose. You are sacraficing low end torque for top end power.

PureStang: Unburnt gas on the catless X will always be there. If you have a tune, it helps. Even with high flow cats on my Bassani I was getting the smell. I got it tuned and it has more or less corrected it.

Longtubes with deepen the sound but make it a hell of a lot louder! Get ready for a pain in the a** install though!

Check if you have a leak. When the metal heats up, it expands the tubes. When it cools, it shrinks them causing small leaks in new setups. I had to tighten mine in stages. Plus as you are breaking the pipes in, the metal will heat and eventually settle into whatever position it is going to settle into. I had to tighten mine after two weeks because things had shifted and changed.

Have a friend either rev the motor while you are under (for god sakes make sure it is in neutral or park). Feel along your seams (obviously don't touch the pipe) for any air escaping. When you find a leak, tighten it down. This can also be done with a rag in the tail pipe if you are a party of one.

Someone else jump in if I am wrong. Check your H pipe again on the driver side. The reducer sits inside the pipe and you may have to pry it up because ford used silicon to form a gasket around it. It should come up more or less easily.

I have seen at least 4 mustangs with this exact same thing so I am going to assume it is pretty common. Not only that but both mine and my buddy's were just like that.

Double check that H because I have a feeling that missing reducer is why it is not tightening on there. I'll try to hunt down a picture or something.

Alright, this is a crappy example but will have to do. http://www.pypesexhaust.com/rpe631.jpg. There is an "optional collector reducer" in this picture. This piece actually sits inside your driverside stock H. I needs to go in your driverside X.

I'd drop it if I could to show you. I will keep hunting for a better pic. But that is the gist of it.

dude, I had the same **** to deal with for a year and a half with my o/r X. The I got LT's with an o/r X and it sounded worse. So I got an o/r H and i LOVE the sound. Not very loud, but the sound, matched with my borla...its awesome

Yeah, another one of fords brilliant designs (the melt on plastic bolts are my favorites though if anyone has tried to take a speaker cover off without first reading a how to). I found the reducer by mistake. I dropped the H on the ground and it popped out. I bolted the driverside of my X up (the bassani was modular) and it didn't sit right so we figured the reducer is probably suppose to go inside the X too. It fit right in and bolted right up. No problems since other than adjusting for the pipe settling.

This is an X pipe install write up. I think the guy is talking about the driver side when he says passenger side, but the 1.5 inch piece of pipe inside the stock tubes is exactly what I am talking about.

His passenger side comment doesn't make sense because the pasenger side has an actual gasket. Copper if I recall which is reusable...Oh and check to make sure that the old copper gasket did not somehow how stick to your stock H. Sometimes that happens. It is reusable, but if it got all mashed up, you'll need a new on. Usually they stick pretty well to the exhaust manifold so most people don't have to worry!
