I've read several of you comment on installing the magnaflow system. I had mine installed. I noticed several mentioned that they disconnected the battery when they did it. I did not. Did this harm anything? Is it too late to do it now? Does it need to be done? What is the purpose in doing it? Thanks.

Droopy, you might notice you gas gas pedal like sticking. Or your RPMS staying higher. It is nothing to worry about, but then you will need to disconnect the battery, and let the comp. reprogram it self. I had that problem with mine. The way that I thought was I am worknig on the exhaust, not the fuse box. I learn something everyday....

I did disconnect the battery, I am a little anal about directions.

I do have a exhaust leak before the muffler and have tightened the heck out of the clamps and it stills puts out some water drops. Any ideas??

Nope! I wouldn't weld it. I want to be able to remove it if necessary.

Mine was leaking after the initial install, so I went back under there and tightened it up some more. I used the 1/2" drive socket/wrench and torqued down on that beeotch!

I had a new system on my Hemi that was bolted up. Struck a puddle at speed, un-intensionally and the force of the water pulled it apart. Have always welded them since then.

A good muffler shop can always cut and splice pipes where nessecary.

Just my opinion.

if you have a leak at the first section, make sure the muffler is all the way forward to the little bung on the stock pipes. then torque the hell out of it. that should solve your problem.

I did all the above (except weld) and I ended up going and buying some U-clamps. I had the stock clamps tightened all the way and there was still water spitting on me and I could feel air. all good after the new clamps. Down side is they weren't stainless steel. oh well... little things.

Installed the Magnaflow....sounds great....install was easy...nice having a friend who owns a muffler shop...only took about 45 minutes to install...no leaks.

I did notice slightly higher idle RPM though...re set the PCM, and still idling about 700 RPM... Not sure if this was the original idle RPM, it seems a bit high though.

Anyone else notice this or is the RPM correct?
