i was just wondering if yall have any complaints about them? i was reading somewhere that said there needs to be a slight modification, where does this need to be done? did they bolt up alright? is there enough clearance? also did yall see any increase in horsepower? thanks for the help...

Well my set went on this past Saturday. Let me start by saying that power has increased thru the entire rpm range. Motor revs quicker and smoother. Noise is a very slight increase at idle but does sound a lot different when gunning the engine. The quality of the parts appear to be top-notch.

Install was fairly straight forward with just a few bumps.

1)Bolt-up at the collector flange to cat connection is difficult. Between the flange, O2 sensor and cat body, it gets rather difficult to get to all of the nuts the way you would like to. May need to add a few washers to bring the nut out away from the lip on the cat flange (you'll see when you get there).
2) Passenger side header got rather close to the frame rail. I cut the stock heat shield to give it as much room as possible.
3) The kit comes with two MSD spark plug wires for #5 & 7 plugs. I ended up using my existing magnecor wires and a two wire connector to keep the wires away from the primary tubes. The MSD wires didn't seem to fit well.

I still have a weird noise coming from the header when I am pushing the engine and hit bumps in the road. I think I have a leak at the driver side collector to cat flange connection as described above. I need to get under there when the engine cools and take a good look at it.
