97 Sc400 Upgrade Help

[scotturnot]

I own a 97 SC400 and am search of info. regarding performance upgrades. All I have done so far is the BFI intake mod. I am searching for the best bang for the buck mods. A friend said the best performance upgrade is in the torque converter, are there any testimonies to support this? What exhaust system will perform without becoming an annoyance in sound? Who makes headers for this car? Anyone that has suggestions of where I can grab some good HP in my SC please LMK. I really am looking for those who have successfully done these upgrades and are willing to share what they have compiled.

Later,

Scott

i would suggest nitrous. about 1/10 the price of a supercharger kit and you can get the same gains.

I have a bfi, full true dual 2.25 exhaust w/ xpipe and a 80 shot of nitrous. Car performs very well w/ nitrous. The exhaust also helps tremendously as the stock is not a true dual and less than 2" in diameter.
