BTW, there IS a difference between the collector/merge tubes, but LG says it's only about 5 rwhp difference for mostly stock engines.

If the car is going to be blown then go with the Pros. The main thing you want on a boosted vehicle is less air restriction. Remember, the cars are limited from the factory as it is anyway, so adding something that is going to force more air through the system needs to be accomodating.

I just contacted LG and spoke with them for a bit about their different Longtube setups. I urge anyone with questions and on the line of deciding which Longtubes to go with to give them a call. Excellent customer service and he didn't seem to mind taking the time to explain to me the details of all the different setups. 
He said the LG Streets are made 2 1/2" to bolt right up to a stock Vette and are designed for stock to very mild modifications. His example was if all you are going to do is Intake/Exhaust then they are perfect and the difference between Pro/Street is virtually nothing. He said it would work for big power head/cam and light boosted applications as well, but you might be leaving 15rwhp or so on the table.
The LG Pro setup is more for big Head/Cam and light boosted applications.
The Pro Super setup is for high boost applications and huge power. This has a different collector design and 1 7/8 primaries. Apparently this isn't available for C5 yet, but I think he said it's due out near the end of the month or so. You can view it on the main page of their site at the moment.
I apologize if I interpreted something he said wrong or misunderstood him, I'm definitely no expert. I'm pretty sure this is reasonable accurate.
I still haven't decided what I'm going to do with my setup yet. I really want the LG Pro's, but I don't know if it would really be worth it or not for $600 more. I think if I were to get the LG Streets, they would be adequate for my goals.

the reason i kind of wanted the pros is becuz they were made by Borla industries, and i already have full borla exhaust and i ordered custom plates...BORLAAA...haha so headers made by borla would be sick

I have a supercharged C5 and run LG Pro Long Tubes (made by Borla) and Borla Stingers. I love the sound. I chose the LG Pros because I fell in love with the sound of the Borla Stinger and decided it would be best to keep the whole exhaust Borla.
If I fell in love with a different muffler, then I would have went with the American Racing Headers.

I'm tired of waiting for longtubes and am now considering going with the LG Street Longtubes instead of the LG Pro.
For those of you with experience or knowledge of Longtube designs and power results, I'd love to hear your thoughts on this. My car is virtually stock now, with only a Halltech Stinger and B&B Bullet Catback. I am planning on purchasing a Procharger in the future and running low boost.
Now, if I were to purchase the LG Streets...what limitations am I looking at when running low boost (5-7psi max)? Would the LG Pro's still be better in this situation?
Thanks!

If you're insistent on LG, then wait for the 1 7/8" for your application. They are nearly a carbon copy of a system a competitor has already been building for years, and is seemingly everything LG has tried to dismiss in that time as being "less powerful".
I admire what LG has done to bring products to market, but they cooked their own goose on this one. They are finally catching on that their design is not the one-all-end-all perfect app for all cars.
The competitors have known this for years, and brought products to market quickly to satisfy that demand.

No flames...
Their competitors, forum vendors too, that have been building 1 7/8" shorter-primary tube systems for many years now.
When they were first introduced (to meet a growing demand), LG did everything they could to try and prove their 1 3/4" system was still the "most powerful".
Many years have past. The sales of those 1 7/8" systems have skyrocketed, not only huge hp FI cars, but even on moderate heads/cam 346s. They work, they work well, and a lot of people know it.
Now, finally, LG comes out with an almost identical product, a product which flat out contradicts all the claims they've been using to put down competitor's product the past few years.
A little ironic.

Streets are the way to go. I've installed them on a couple of C5s. The quality, fit and finish are very good, they sound great and perform very well.
Pros are not worth the added $. Even for Big H/C or FI I'm not so sure either 5 hp maybe?
With the money saved you can do a cam which will give you way more then 5 hp.

I finished installing the streets a few weeks ago. I wanted the streets because of the 2.5 in design. They will mount up to any "stock like" cat back system. The 3 in system would be more advantageous for a blower I would assume, but either would work. I don't have a pre LT's baseline, but just had the car dyno'd yesterday with a very similar set up as you and made 357 HP and 366 TQ. I was pleased. Oh, and if you decide to install the system yourself have a buddy come over and help. I did it solo and having a helper would have been HUGELY helpful. Good luck.
