Over the axle true duals with DS loop - Pics inside

Here's the setup - Hooker LTs going to Dynomax 3"-2.5" reducers to a custom x-pipe, back to twin Dynomax bullets, over the axle and out through Hooker large bore exhaust tips. That's a Jegs driveshaft loop in there, BTW. Sorry, no videos at the moment, but believe me, it sounds awesome.

Looks nice, but I'd be curious to see the pictures depicting ground clearance. It looks like quite a sacrifice on ground an axle clearance.

BTW, keep eye on your fuel pressure. You may be significantly heating up the temprature of the fuel, and increasing pressure based on how close those fuel lines are to the exhaust.

Ground clearance isn't too terrible. Its a non-lowered car, and the pipes don't hang down any lower than the flanges for the LTs.

About the fuel pressure, I was already planning on shielding those fuel lines.

What did you use for the rear piping?? Like..... To make the exhaust exit over the rear axles? It looks like it's a prefabbed piece? Is it? I'm wondering if something from say.... an LT1 impala would fit?

I've currently got true duals - but they dump under the car... It's annyingly loud.

Shawn, what mufflers are you running? I had the dynomax bullets and it was insanely loud. I took the advice of my friend and got some Borla XS mufflers. It is not a bullet style, but it is straight through. AMAZINGLY quiet for a straight through design. I swear my car is as quiet as a stock camaro. Its a little louder than a stock LS1 I heard the other day. These mufflers were rated best power and quietest a few months back in a mustang mag., i.e. they were the quietest, but also made the most power. I'll see if I can get some sound clips.

There are no prefabbed pieces there - its all custom. A local shop did all the work. All of the pipes are just regular 2.5" aluminized tubing.

Thanks for the compliments guys.

How much did all that cost??? Looks like something I would want to save for.

And we need some sound clips/video.

It was about $500 for the fabrication. I had the headers already in, and I provided the tips, mufflers, and reducers. They did everything else (including the x-pipe)

I am at school, away from my car (stored at home), so no videos for awhile. I made a video of my car with open headers, and it didn't sound very good anyway, using the microphone on my digital camera.
