Considering doing this in the long run and was wondering if there were any issues with getting a true-dual setup, ANY issues at all that might get in the way or prevent something from fitting ect. thanks

well, if your going with an Xpipe, you will most likely have to remove the factory crossmember thingy that acts as a driveshaft loop, but is just a stamped steel plate under the D.S. behind the tranny
you can mount exhaust hangers onto the bolt holes left there, when you remove that plate
also you should use a factory style exhaust hanger on the passenger side of the tranny, to bolt to the pipe after the rightside header
make sure your exhaust guy doesnt the piping too close to the floorpan, or there will be horrible vibrations

i just got a dual system with my MAC's put on a couple of weeks ago and the dumbass put the driver side pipe from the header to the Xpipe too close to a bolt under the driver seat, and the pipe is not resting on it, and also bolted a hanger to the torque arm (bolt flew off shortly after)
so i gotta get mine altered quite a bit

so if you do get duals, print out a few pics of the setup you like, and show your exhaust man EXACTLY how you want it done

Make careful consideration of the fuel lines. If the exhaust pipes run too close to them, you could have heat problems (vapor lock?). My fuel lines were moved further up in the driveshaft housing by reversing the brackets. If you go all the way out the back, you may need to either remove the upper panhard bar or relocate the lower one (especially if the car is lowered). I opted to relocate the lower one because I roadrace the car. Don't weld the whole system in place - use flanges so you can drop it if needed to work on the drivetrain.

I would not recommend bullet mufflers alone for around-town driving. Cops will hear you a mile away (literally - no joke). I got nailed by a police officer who didn't even see me, but heard me get on it, and just followed the sound. Yes, I was speeding, but he never would've known I was there if not for my exhaust. I added cats to my setup to quiet it down. You could use Spintech or something similar.

CySevens, That is the best setup I have seen especially for those of us who have a TA and want to keep the rear facia cutouts filled.
I was wondering if I didn't lower the car would I have to do anything with the either of the PHB's? Could I still fit both pipes over the axel with no suspension modifications? Also could you give some more details such as type of X pipe, who did the work, size of pipe? I'm assuming that its 3" down to 2.5" over the axel and if so where does yours change to 2.5" Do you have any pictures of the axel area because the cross beam on the lift covers it up?

Anyone else have pictures of duals over one side without having to remove upper PHB?

Do these cars need a complete 3" exhaust system to perform well, 410-430rwhp? I would put dual cutouts.

Sorry so many questions, but I need to learn

You would probably have to do the same thing whether or not your car was lowered because the suspension can still travel just as much (softer springs). The only other over-the-axle setups I've seen had the upper panhard rod removed (and those cars were not lowered). Some of those cars, I believe had 3" all the way back, so they needed more clearence. Mine reduces to 2 1/2" just after the bullets so I am still able to remove the tail pipes and dump it before the axle if I want to for track use. I'm also going to eventually add flanges just after the cats and have off-road pipes made to replace them for track use. This way, I'll have almost a full 3" (well, probably equivelent to 2 3/4" with the non mandrel bent pipes) system. X-pipe was custom. It was all done at a local muffler/exhaust shop.

As far as whether you need a full 3" system, probably not unless you are running nitrous, forced induction or a stroker motor. I eventually plan on forced induction combined with a stroker assembly.

And, Tony, beware! Just because it hasn't happend to you yet doesn't mean it can't or won't happen. It already happened to me, so I can speak from experience. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" title="" alt="[Razz]" src="gr_images/icons/tongue.gif" />

Mines not to shabby either as I have my x-pipe custom made, bullets added and painted with turn downs right before the axcel. All this for(300.00) and Deer Park does some good work as well!!!The sound is really nice and deep!!!! <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

my exhaust man did a kick butt job. 200 bux, i provided the bullets. I've found that as long as you aren't romping on the gas, the cops leave you alone. I live in close proximity to a doughnut shop (aka police station) and have to drive around them constantly. No probs yet. I can cruise normally without any more noise than most of your louder cars and trucks. Now when you hammer it, totally different story. Sounds like a nascar at bristol off of turn 2. Terribley loud, but oh... so nice!

So would u guys reccomend no cats/or highflow cats and im assuming u cant go over the axle without removing the upper PHB?? also wondering what the most youve spent for your custom job?

I have about a total of $850 invested, all parts and labor included.
