i got this system from performance peddler for under $550. it looks nice. the dual 4' tips are beautiful. it was a challenge getting the mufflers aligned properly.

I have been looking for an exhaust upgrade for the past two months and I think I have finally settled on this system.

It is the top system w/o precats. They don't have a picture of it individually.

But a couple points. I found a place that has the front Y w/o precats and a highflow cat, that replaces all of the other cats, for 234.00. I am then going to purchase the CC Magnaflow with LT1 tips for 259.00. I do not need the rear Y because I bought a new one last year with the crossover pipe on it. The whole system is $550.00 shipped.

I was going to go with a true dual system but the only one I can find is for the LT1, unless I went with a non cat system like you are looking at, and I have the L98. I know I could match them up anyway but for the difference in price I doubt I could see that much difference or any at all. The cheapest I have found the front cats for the :LT1 setup is about 350.00

I also want to remain street legal. They don't smog here but some of these yahoos do check for a cat.

Also, I have found the rear Y for 129.00 as an FYI.

The other good part about this system is, if I wish to, I can replace each section one at a time if I decide I don't want to lay down the whole 550.00 at once.

Just a thought! Good luck. I know it's a pain deciding what to do when everyone is out to rape you for every cent they can get.
