still will depend on where you live. I can't imagine they start a FEDERAL inspection.

there are alot of places in arizona where I could go and not worry about inspection or anything, State regulations have quite a bit of precedent over federal laws.

I'm now running Hooker mufflers (mainly because they were the quietest), but when I put the O/R H in I'm going to put the steeda mufflers back in as well.

I'll get a clip of the exhaust when I get it put up, and I'll have it running with a Condenser Mic, so it should give you a better idea of what it sounds like
Thanks

I'm going to look into it. Ruffly how hard is it to install (04 GT) & how long (# of hrs) would you say to install?

Thanks again

alright, so much for being a GOOD fit. What I thought was going to be a 2-3hr job, turned into 10-11 hours. Started at 11:00 in the morning, finished around 10:30 that same night. Zero stops, nothing.

There was a leak, and after 11hrs being under a car by myself, i was too annoyed to finish myself, so took it into the shop and had those guys do it (only 30bucks to fix the leak).

Louder than F*ck now, unbelieveably, but I think it sounds good, I can feel a tad of a difference, not much though. Turns out that my other O2 sensor had two wires severed, so what that was doing as far as keeping the car from switching between open and closed loop, I dont know.

But, got it right, turned off heater banks, O2 sensors, and OBDII tests, now running fine.

Looks like the only problems I've been having are pure maintenance issues.

Although I want to find some way to make the car appear to have Catylitic Converters so I can pass inspections later this year (they only check with a mirror to see that you have them)

Why wasn't it a good fit? Shouldn't take 10 hours to install a midpipe

I've had 3 different mid pipes: BBK catted x, pypes o/r x and summit o/r h. And I've had leaks on each except the summit, and was able to fix all of them with ease. Where is your leak coming from?

i *think* it's coming from the drivers side manifold. that's where i could hear it more. i've replaced the pass. gasket like 8x and tried adjusting but still no luck. i guess my only solution is long tubes

my leak was at the ball and socket joint on the drivers side header.

the pipe that was on there (JBA) never had any problems whatsoever, other than having to replace the catylitic converters.

anyway, they just loosened and adjusted the pipe to get it to where it isn't really leaking, or if it is, I certainly cant hear it.

the real problem was the tightening of the bolts on the passenger side flange coming from the header, why they don't have the same ball and socket type joint, Don't ask me.

anyway, I just have to tighten the catback up a little bit, and it should be perfect.

well, number 1 thing you should know about me, the reason I sit behind a desk all day (and the reason my degree is in what it is) is because I'm horrible when it comes to turning a wrench. I've gotten alot better, but I'm still not the best

anyway, one of the main reasons was the bolts on the passenger side flange to the header, and the fact that those bolts aren't tac'd into place, so I had to use one hand to hold the bolt, and the other to put the nut on, in a very tight space.

The other reason it took so long, is I may have used a nut that was slightly small (again, this is where my lack of mechanical skills comes in), and it actually went through the flange, so we had to take the entire passenger side down to get the nut all the way through the flange and then bolt it back up.

Not to mention, 7 of those hours I was doing everything solo, by myself, with no help, so I had to kind of do 3 things at the same time.
