Exhaust Mod + Flowmaster
So many of you guys have PMed me about by exhaust over time, and I've posted about it before. First things first, let me say this won't pass inspection in Texas, I gotta get rid of it or cover it for next inspection. But it gave the PERFECT sound that I was looking for.
After the cat I have the pipe running to the Flowmaster 40 series muffler, which is a SI/DO, then dumps before the rear axle. Just behind the flange that joins the two pipes, I cut a .5" x 1.5" square out which is parallel to the exhaust tubing itself.
Started it up, JUST what I was looking for. Nice mix of the Flowmaster rumble with the raspiness of no muffler. It's quiet at idle, but you rev it at all and it has sorta an old car sound to it, ever so slightly cammed (it's not). Perfect mix of the Flowmaster and the hole. Under load the Flowmaster is dominant until about 2000 then the pure exhaust overrides the sound (it's loud!) and pretty much dominates to 4500 or so.
I'm going to try and get a sound clip tonight.

I believe I will just weld a peice of metal compeltely over it, then grind it off after inspection.
I was hoping Oklahoma would be cool with it, since that's where I'm going to college, but alas, they don't allow ANYTHING that raises the vehicle noise level or bypasses the muffler. At least here you can have a cut-out.
At some point I will probably replace the hole with a cutout, however I'll be buying two caps to the cutout, one with a hole drilled in it and one solid. I don't want the full bypass of no-muffler sound.

RangerPilot, Oklahoma no longer has inspections, so your safe as far as that's concerned. I haven't heard of anybody getting a ticket for illegal exhaust in over 30 yrs. If they start handing out tickets for exhaust they need to start with those annoying bee filled tin cans the import boys are running. Not sure if it's Oklahoma law but around here it's the stereo volume you need to keep to a certain level in certain areas. I do think that this law does not apply to rap though because I can still "feel" it shaking my house and truck.

Hmm that's weird, on the OK Department of Public Safety it said something to the effect of "no person can have any sort of hole in their exhaust system". BUT, I guess if there are no inspections, what are they gonna do, right?
I guess I'll re-register it when I go to college.
If you want to change states or whatever you gotta register it, then get it inspected, right?

Don't quote me on this but I think as long as your permanent residence is in 1 state and you are just going to college in another I don't think you need to register in the state where you are going to college. You do live with mom and dad, and will be in a dorm or rental property, right?
What do you mean by a hole in exhaust system, the dumps?
When you get up here you will see a lot of Texas plates, they have been driving around that way for a long time.
I have heard that you need to have Oklahoma plates after 3 months of permanent residency though.
Check into everything to be lawful, I'm just telling you what people get by with up here.

I'll be living in the dorm.
I'd reregister there if the laws are more lax on what I can do with my truck.
And it's a notch in the tubing before the muffler, that's the "hole".

Only thing that sucks is if you register it to your dorm room address, itll change the next year, and the year after that most likely. Unless by some miricle you keep the same dorm for all your time i would leave it registered at home.

Hey Zack, what college are you going to again, in june, i'll be moving out to Tulsa to attend Spartan to get my Associets of Aeronustical science or something of that nature.be cool if we could hook up. As for Legitical things with your exhuast, do what i did, or say am doing. when they redo my exhuast, they are putting in this really cool y splitter. you can cap it for inspection, once your outta the shop, (and the exhuast cool enough) take it off and let her sing.
