I am already missing two mufflers.....maybe 30 pounds......I wouldn't mind losing another 15 pounds......

15 lbs wont conclusively show up on a dragstrip timeslip either...
and i doubt substituting the resonator for the X-pipe will save 15 lbs. maybe 10 at best...
dont get me wrong. i`m not saying that weight reduction isnt benficial, but 10-15 lbs alone isnt going to offer a noticable gain. but as a small piece of a much larger weight reduction effort, it is helpful...

BTW 15 pounds equals 15/3250 pounds equals .00462...so removing 15 pounds reduces the weight of a 3250 pound car by about 0.462% which has the same effect as increasing the horsepower by 0.462%..
So with say 350 horsepower this is 350*0.00462=1.6hp....no big deal, but like you said every little bit eventually adds up...
Pretty sure my B&B resonator weighed 18 pounds

There is nothing on there for the 2&3/4 piping and the spacing looks to wide to go on the LT1.
I personally am going to wait on production of these by racer, or try to rig a magnaflow tru x resonator in place if the x-pipe does not come through production.

I'm using a xpipe and two dynamax resonators. I'll see if I can get under the car and take a good picture to post.
Racerx07cc, I think you can make your product better by having the X then placing resonators behind the X. I installed an X pipe inplace of the resonators and the sound volume went up. not down.

I went with a magnaflow x pipe with two 4 inch dynamax resonators.

Racer,
When you get the production pricing, let me know, I am interested. My LT4 has as LT1 exhaust system on it, no H pipe. So this might give my car back what its missing.

I've seen a lot of people post that they wanted a little more sound but didn't want to make their car too loud. I would recommend they try installing an X-pipe in place of their resonator before investing in an entire aftermarket system or even changing mufflers. You might find that it's just what you're looking for, sound-wise. The factory LTx mufflers have a very nice sound with such a set-up. And I know enough about exhaust theory to know that there is no way a an X or H-pipe will not increase performance compared to the resonator or straight dual pipes. And say what you will about SOTP results but the low end gain in response alone should convince anyone whose ever added an X or an H into an existing system that it's beneficial. Thanks for your work and efforts in bringing a C4 product to market for which there is plenty of demand and is of real benefit.

I'm actually looking to quiet my system down or at least loose some resonance. I'm running a full Power Effects system on my ZR1, which I generally like, but the resonance can be bad. 
I'm either going to install this X-pipe after the resonator (looks like some cutting will be required) or install a 3" Ulra Flow resonator with the x-pipe built in. I'm waiting to see what the price difference will be. If that doesn't do it I may have to ditch the PE system.
Glad to see someone doing some C4 development. Keep it going Racer

Hi..... Can anyone tell me where i can find those bands/clamps
that are holding the x-pipe on? I'v looked at the auto parts stores
in my area and nobody seems to know where to get them. Thanks,
Rick

To the poster asking about band clamps... I keep them in stock, sized from 2.25" all the way up to 4" (including 2-3/4"). I sent you a PM as well...

Walker makes these clamps, and others I'm sure. Any performance shop will have em.

I can see where it would make more power. Especially if you are exhaust limited. The center muffler, our resonator muffler is a restriction. The X pipe is a proven piece on many cars. I cant believe we are giving this guy the third degree. He is trying to improve the performance of our cars, THANKs. There are BS products on the market, yet you have all bought some of it. The X pipe arent BS, and if they were why do so many people pay for them.
To tell if its going to help out, do a before and after dyno. Let a skeptic do the test on a independent dyno.
PS, I got rid of my resonance by putting lower gears in, so I am never near the 1500rpm drone
And the clamps, I love these, Torctite's lap joint/or butt joints. I bought mine of of that *bay place, and my exhaust leak I had a couple months ago went away. The flat band clamp couldnt seal the pipe after the cat going into the flowmaster cat back.
