I decided to buy an 01 S4 rather then a G35X. Im goin to buy a few parts but not sure about the exhaust.I know im getting bailey Dvs, Chip, Samco hose kit, RS4 Replicas wheels and S-flo intake. I want a aggressive exhaust Down pipes and all any suggestions would be helpful...

 

You can get the AWE downpipes and Twin 1 catback, the twin1 is louder than the twin2. They are pricey but I think they are pretty good. Either that or you could get the VAST piggie downpipes for like a third the cost and get a custom catback with your choice of mufflers. You could do VAST piggies and custom exhaust for like a grand as oppossed to spending 1500 one AWE downpipes and 1500 on AWE twin1 catback. You'll save enough to get the AWE intercoolers and still have 500 left over

 

Go Stage III K04s and the fuelling kit

 

any exhaust is better than stock... get piggie downpipes

 

Ko4s come later but could I do piggie downpipesand a Twin 1 or borla cat back if I wanted?

 

ASP DP's & exhaust. There is a dyno video of my car, it sounds sweet!

 

is it easy to install with a lift or are there welds that need to be doneandalso anyone know what AWE tuning facilities charge for installs?

 

The cat back is 30min in a driveway. The DP's are several hours, even with a lift. No weld, just no room to take out the 3 little nuts. Look around in the engine bay, see if you can see the turbo's, that's where the DP's attach. Then look under the car, see if you can see the turbo's.

 

So you have to do it blind and by feel pretty much?

 

Yea, kind of, it's just really hard getting any kind of tool in there. You need like a 30deg bend, then another 40 deg, then 2in extension, to get 1/16 of a turn on the nut.
