Hey guys I'm new here my pops just picked up a 2007 997 turbo and he had a couple of questions so I figured I would post them here.

1)The car has a Techart exhaust on it how can I tell if its the race or sport?
2)What have the proven gains been for the system?
3) Does the car need a retune with this particular exhaust since it has cats? So maybe the car has already had a tune?

Then he wanted to do a couple of mods to the car what is your take on the 2 items
1) A stock sized set of Forgestar wheels with PS2's ( I talked him to into them because I just got a set for my E55)
2) A set of H&R/champion lowering springs.

Thanks in advance

 

for springs i would go with GMG springs and sways...its an awesome upgrade, makes it a different car...do a search and read the threads on it

congrats and welcome

 

Ok , thanks. He is getting older and he told me he doesnt really want to compromise the ride quality very much.
