Someone please check my tuning

[99GSTEclipse]

OK, for you who dont know me, i just bought a 1999 GST Eclipse Spyder, and I am making my first order on aftermarket parts, and I would like to make sure all of this looks fine, and make sure that it wont screw up my car, OK, first thing in the list that i am making on this order is an Apex-i N1 exhaust, then a Apex-i N1 downpipe, I am also getting a new filter, a HKS Super Sequential Blow-off valve, and finally a unorthodox underdrive pulley. All of this stuff in my mind, i wouldnt think would cause any problem, to the car, but im just double checking. The car is a completely stock 1999 GST spyder as of right now. This is the first mod order. I appreciate the info, thanks.

you might wanna check out buschurracing.com and dsmtuners mod path pages.
Its pretty much a guide or list of things to buy that will help you get started and help you learn more about the stuff instead of just buying it.
I wouldnt recommend a underdrive pulley. Mainly you want to open things up to let it breathe better.

Example: Exhaust, K&N intake filter, etc....

The Apexi N1 exhaust is very nice and is not very loud at all.
Also check out dejontool.com, they sell upper IC pipes to mount Blow off valves on.
