Default X-Pipe For LT1

My '92 has 2.5" dual exhaust with no converters or resonator. I am looking for an x-pipe to cut down on some resonance/drone. I am trying to decide which x-pipe is the best bang for the buck.

Dr Gas:
Couldn't find a product link

eBay Special:

This is real sweet, but too costly:

There is also the possibility of having a muffler shop fab one up, but not sure if cost and/or performance would be as good as an off the shelf unit.

Any other suggestions would be helpful too.

I have that $25 Ebay version on my car in 3". No trouble with it! I painted it black to prevent rust on the welds.

Unfortunately I hear Dr Gas went under too bad...swallowed by the giants and the chinese crap from ebay.

Doubt youd see a difference between most they do about the same thing. Pick one, shoot.

Thanks!

My local shop fabricated one for me and they did a fantastic job. I watched him cut and bend everything freehand, and it looks great (too bad it's way up under the car).

I have no resonator, and no cats. The x-pipe did not really help with the drone. Changing mufflers made the biggest difference in drone. Maybe, MAYBE, moving the x-pipe an inch or two in either direction might have made some difference, but I didn't want to waste time or money on that little science experiment.
