i agree... and congrats on finishing the setup.. sound pretty sick... cant wait till mine are on... and itll break-in in no time... enjoy.. TIM

 

That sounds sick!

I now found what Im spending money on next.

 

How loud is it in db? over 95 db?

 

What is db?

 

db is decibles, a measurement of sound. Just curious did you get cats with the mid-bed O2 sensors or just insall them after the cats?

 

I left the O2s in the stock place in the stockpipe. There are 2 before the cats and 2 after. I had to replace the 2 before the cats because my truck ran like crap after the cat replacement. Does this answer your question?

 

In a way. I have 2 before the pre cats and 2 mid-bed in the main cats. I want to install a true dual system and i hear that if you dont have the O2 sensors in the right place after the mod the engine will run like crap. I want to simply replace the OEM equipment with Magnaflow highflow cats and flowmaster 40 series delta force mufflers havent decided an exit style yet. All 2.5" pipe. I'm just trying to research it before i drop all the money into it.

I'm jet engine mechanic for the air force for the past 3 years my vehicle engine knowledge has gotten rusty.

 

I was told by the lady at Troyer PErformance that as long as the rear sensors are as close to the cats as possible ( should have the O2 bungs in them ) then it should all be good, along with the air tube. I will be buying Magnaflow part #94006 ( rear Hi-Flow cats ) for my truck.

 

This may be a dumb question but whats the benefit between a h-pipe vs. an x-pipe?

 

H pipe will give a deeper sound, and it will balance out the exhaust pressure.

X pipe combines both exhaust manifold systems into one, making a louder sound, giving the greatest back pressure with possible noticeable torque gains.

 

No offense, but in my opinion that sounds really bad. Loud, obnoxious, and no tone. Reminds me of our old school tractor on the ranch.

Your low end torque has got to be suffering with no mufflers and high flowing cats due to a lack of backpressure.

But hey, its your truck. If you like it, thats all that matters.

 

Some times peoples opinions are best left un said... thats my opinion

 

2x on that Typow07 Msall150, what kind of exhaust do you have? I can't stand the thought of spending hundreds of dollars on something that pisses me off when I rev it up because I can't hear it. I spent 8 years hearing Chevys and Dodges blow my exhaust away and finally I've got an exhaust that has that loud redneck beat to it, kind of like those $300,000+ cars that scat around the track on Sundays No offense, but if you don't like it then go to another thread to post comments. My dad says it's too loud to but he's 56 years old and when he was 24 his Harley's, Mustangs, 1955 Ford truck, and Corvettes were loud as fukc. I've never heard a tractor sound like that but when I do I'll buy it to drive back and forth to work.

 

I have the Roush Off Road exhaust. It is plenty loud, but also provides great performance and a better tone than just about any other exhaust out there.

I can tell by your post that all you want is to be "louder" then the rest, having that "redneck" sound with disregard to good tone and performance, so thats great that you got what you wanted.

I'm not trying to be an a-hole. This board is about opinions and trying to help one another, I'm just throwing out an opinion and a constructive argument. Straight pipes are NOT good for performance, its been proven over and over again on dynos.

But like i said earlier:

 

I know what you mean...Yeah the performance aspect may not be there with straight pipes but it's cheap and loud and I'm no dyno expert. I'm just glad she's still running with 199,000 miles. Heh, I'll let you off the hook since you have that Roush exhaust...they're one hell of race team. Ford's Rock any way you put them. Post a vid of your exhaust if you can, you never know I might want a muffler one of these days. Have a good'en.
