Christmas mods, QTP headers and true duals Over the axle For Christmas this is what I plan to buy myself.
Stainless steel QTP headers with HVMC's.
Race style headers with no AIR or EGR fittings. All of my AIR and EGR has been removed and I currently have block off plates on the Hooker headers.
The other change I would like to make is custom true duals over the axle with an x-pipe to take full advantage of the high velocity merge collectors. Not exactly like the picture since I would not have the center exit exhaust, just true duals and tips.
Link
I would however copy the dual's over the axle with Borla XR-1, Dynomax, or proflow twisters mufflers at the rear.
These mods are for both power and sound since I hate the raspy sound I've had with every exhaust I've ever had on the car besides the stock setup. It should free up some hp, increase my ground clearance, and possibly weigh less or only equal to the current setup. This exhaust will probably be the final mod I need to complete before getting tuned, since I don't plan on any more power mods.

Typical true duals exhaust post. I just wondered what people thought about doing the true duals over the axle. I know it's going to be a tight fit with 2.5" tubing, but my only concern is the stock pan hard brace. I've seen pics of people running true duals and keeping the stock pan hard brace.

I definately wouldn't go without the brace because my car is lowered with Koni's, bigger sway bars, wider tires etc.

The brace is not needed. It is perfectly safe to drive with no panhard brace on and off the track. I had mine off my old third gen for a long time with no ill effects. It's there to add support to the panhard bar for cornering, but if you are into drag racing, ditch it. Hell, get rid of your front sway bar as well.

I'm sure people have gotten away with not having the barce on their car but your assumption "It is perfectly safe to drive with no panhard brace on and off the track", is just that, an assumption. It's also a risk I wouldn't be out proclaiming to be fact.

Just because your mount hasn't broken/failed doesn't mean it won't happen, or happen in an abnormal driving situation aka during an accident causing you to lose stability in the rear.

Oh ****...here come the internet mechanics. Dude, don't listen to these people (not that you are anyways). The upper panhard brace is there for a reason...
Anyhoo, that's exactly what I bought myself last Christmas (well, the true duals, as I already had the Kooks headers). I don't think they make 2.5" Borla XR-1s...maybe I'm wrong. I think they only offered them in 3", which might be a problem. I think you can squeeze the 2 2.5" pipes over the stock upper panhard brace, but the BMR relocation kit makes things MUCH easier.
Who are you having fab them up? Just make sure they know what they are doing...this setup is not easy to make.
