Question slp ls6 vs fast 78

sup guys im going to get some parts for my car in a week or so and i am wondering what mani would be better.
i can get the fast 78 from a local shop for like 650 and the slp ls6 is like around 550 for one of the big parts places. i want to keep the egr for the smog crap so thats why i was looking at the slp ls6.
i looked at the fast and they say the egr will work but the hole is just not cut out.
im eather going with a ported stock tb or a summit racing 80 mm tb.
does all the colant pipes come with the slp piece?

you can buy a used ls6 intake for 300$. the FAST will give you a better gain, but doesnt have EGR to my knowledge. you can have the egr tuned out its not gonna fail you on inpection unless you lvie in a really strict place like cali

To install the FAST you will need to buy a coolant by-pass kit seperately. To add EGR to the FAST required drilling a 30mm hole in it. Go to the FAST web site and download their install instructions. It's all in there including the LS6 part numbers for the by-pass parts.

Like Tainted said. Tho personally, I'd forget about spending coin for a FAST 78. LS6 intakes are great with a ported tb. Only way I'm gonna upgrade from my LS6 is to go with a FAST 90/90 setup.

Ditch the EGR.
