Best LT's catted Y combo?
What is the best combo? What exactly will I need after I purchase Lt's and a catted Y?? Will I need o2sims or what? I already have the money, but I need to know what else will be needed. I guess a tune is not needed i heard from my other post

how much money you want to spend??
Personally I don't think you can beat the Pacesetter and TSP 3" catted Y setup that TSP offer. It's great value for money. You'll also need some o2 sims for the rears and extensions for the front o2 sensors.
But there are lots of options and most LT's can be purchased with a catted variant, although some would require you custom fitting the cats to an ORY. The cats on the TSP setup are also very good ones.
No a tune is not needed, but may be of benefit if you don't plan on any more mods in the near future.

I think slpss has the best LT and catted-y combo. I will be going for something pretty similar.

You probably should be more specific as to what you want, in order to narrow down your search. If money is no object then there is no beating the quality and hp gain of the QTP's & HVMC's. If money is a problem, then the best header for little $$ would have to be the pacesetters hands down.

There is no "best combo". It's a matter of personal preferences, tastes, goals, criteria, etc.

As far as there being a "best" combo.....I think the QTP's w'HVMC's have proven to be the best when it comes to power gains. As far as quality, they are one of the best in this area also.

I am biased, but after having my custom Y on my car ... i'd never go to a prefabbed setup because it'll be hard to beat the fitment to your car. I've got Jet hot LT's, RT 7000 series 3" cats, and a custom 2.5" ypipe. It gives me the best ground clearance of any exhaust system I've had, as well as excellent power.

Cut the collectors back, flange the cats to the collectors
Cut mandrel bent pipe to fit to a flowmaster 2.5"-3" merge collector.
Weld the stock Ypipe brace (pass. side) to the Ypipe so that it could use the stock brace.
AND
Install my hooker catback. So delete whatever the going rate for a catback install and that'd be what they charged me for the Ypipe.

I have the TSP catted y and pacesetters. You'll want to get the 24" extendors too. As far as the sims, well i didnt bother. I just zip tied my downstream o2s to whatever was close by. My Vinci Hiperformance tuner took care of the rest. No check engine lights. Then I used the tuner to advance the timing 10%. That should do until i take it to the dyno.
Very easy install...when compared to installing headers on an LT1 car (nightmare). The only thing I had to do was cut the tab off the drivers side of the block with my sawsall. I could have just opted to jack up the motor though, but i wanted a piece of ls1 in my pocket!
