Did my true duals, and now ALL kinds of problems!!
First of all the car is damn near to loud! I did the Pacesetter LTs with 3in. X pipe and two bullets...I went with the longer bullets. Anyhow, I can live with that. The problem is there is hardly any ground clearance now. I had to go under the tranny brace because I really dont know how I could have done it any other way. But wait! thats not the worse problem, the car now stumbles a bit under light acceleration, mostly around 3K rpm. Now since I just did headers most would think a plug wire is burnt. But I checked several times and all plug wires are not even close to the headers. So this leaves me with a couple questions. I did get rid of the AIR and EGR. As of right now the EGR vavle is still on the intake but the tube that would lead to the headers is blocked off. Could this be my problem? If not does it sound like my opti is just deciding to crap out now? What gives! thanks for any input

One tiny little leak where the x connects in the middle. The plugs were all gapped good. I just took it for another longer drive and got on it and now the miss/stumble seems to have almost went away. Only noticed it once. I dont know if it would have anything to do with starting it and idleing into the garage and back out a couple of times on open headers....concidering it only ran for maybe a total of 20sec. each time. Who knows, we'll see what happens I guess.

Never touched the heads, and the O2s are a good point Kmook. I put the old ones back in (have about 95K miles). I read a couple weeks back on here that the oils burning from new headers can screw up O2 sensors. I figured I would drive it a couple days, and then retorque all headers bolts and install the new O2s.

I have the LT4 KM installed. Also, I just got done taking a little road trip the the exhaust bottomed out twice when I hit a little dip in the road and the cars suspension "sunk" down a bit. I need to rip off the exhaust and start over I think, at least from the headers back. I dont know how to go about getting better ground clearance.

With the 3" true duals, you're probably losing about 3/4" of ground clearance. I dont know if your clamps are facing downward, but thats about another 1/2". So right there is roughly 1 1/4" of clearance lost.
Don't rip that exhaust off, find a way to make it work.
