Just like the title says....
I just bought it on Saturday and love it allready. And I'm allready thinking about mods to do...
I'm pretty sure I can do an intake for pretty cheap.
What about exhaust? What is the best size? Would it be better to do single or duel?
Any other things to do to the engine? Other than Turbo,*/C, or NO2
How much can the N/A trans handle?

i've looked into some of the possible alternative exhaust options. my findings as well as the findings of most of the people on this board, aside from a high flow cat, the stock exhaust is plenty and isn't holding you back.
some of the guys here are putting magnaflow mufflers for camaros but there is no perfomance advantage to it, though it does sound better.
do a search for PEMs as far as manifolds go. they're pretty effective and much cheaper than headers. also do a search for willwren'* ported lim thread. those two mods together seem to make the L36 come alive.

Well I'm not looking to spend a lot of money on one thing.
I'd rather spend $1000 on a bunch of stuff than on one thing.
I'm more looking for cheaper things to do to start with. You know $200 or less
I figure that I could do a fenderwell intake myself from the local home improvement store.
Get a new muffler or make my own dual outlet from the AutoZone or Advance.
I know I probably need to atleast check about doing a tune-up. What all should I check/replace?
Anything that is usually missed on these things?
