RX300 Performance Upgrades?

[ptgtguy]

I'm trying to help a friend of mine improve the performance on his 2001 RX300. The only upgrades I can find are a K&N Air Filter and a set of Eibach lowering springs. I'd like to find a better air intake and upgraded exhaust amoung other things. The TRD website only shows an air filter. Any suggestions?

I've got an Exhaust(Sebring Inc.) that looks like this http://cgi.ebay.com/ebaymotors/ws/eB...spagename=WD1V
I'll trade it for your stock RX300 Muffler!!! Wifzilla wants the stock muffler back on her 2001 RX300........

I have a 1999 Lexus 300 and wish to upgrade the body to a slightly better looking model. Any ideas how to reach the person with a high milage vehicle which might be suffering the typical engine oil gelling bearing failure? Major transmission problems or both? The plan is to transfer this new high performance motor in the next month or so. e-mail can be used raneads@yahoo.com

I got a 1999 RX 300 modified slightly by adding a performance chip
and results were HP improved by 40hp...much smoother and sporty..
takeoff is sweet..i also want to supercharge it but not really sure..asked a guy about it said possible but costly and improve HP by atleast 120hp...
