my older brother and i share a 94 gsr that or parents let us drive, my dads old car, he got it when it had about 90,000 on it i started driving it with about 103,000. im not srue about the first 90,000 i knwo he was decentlly nice to it but i also know that he occoasianlly guns it. but on to the problems

1. at 3,000 rpm to about 3,400 my exaust gives off a high pitch buzzing noise. we put teh car up on blcoks and reved it to 3,000 to hear where the sound comes from it sounds like ti comes from the a-pipe i think it's called but where the 4-2 header sonfig on stock turns to 2-1 ne help in getting rid would be helpful

2.at high rpms my cars gives off a white smoke around 7,000-8,000 rpm's. the on time i acctaully reved it there and kept it for about 5 sec i was getting so much smoke taht the wind was blowing it up around teh entire car not srue what it may be but is prolly in conjuction to my other problems

3.my car burns oil BAD we lose about 2 quarts eveyr 1,000 miles the oil place fills us up for no charge thats sorta why we go there instead of changing it ourselfs but it's just a nuesance at the moment

4.exaust tip is pitch black the residue wipes off easilly but comes back imeditally i assume it is prolly fuel and is also causing the white smoke or it may be the oil not sure

5. my final problem in march we had to get a immesions testing with or inspection the limit is 136 and we got exactlly 136 so for this year we don't have to do somin about it but next year we will if we get a tune up will it cut my performance if i am running rich? i have been notcing that my car seems faster then it sued to be when my brother first got hold of it, from a 20 punch race my dads wrx only beat me by about a car length to 80 havn;t gotten a chance to race them heads up but the 4wd would kill me then. anyhelp at all is appreciated thanks
