so ive been running my complete exhaust dp, upp, and turbo back for a while now...and no problems but all of a sudden yesterday i got a boost leak and car ran like crap and sounded like i was running open down pipe...i tightened the bolts on the downpipe but it didnt help...could it be somethin else?

 

It's probably your uppipe, do you have a boost guage?

 

look for black spots where the exhaust is leaking

 

yea i do have a boost gauge...well factory one...n yea it looks like its definately leaking boost...ill try to see if i can tighten the uppipe...dont really see blk spots...

 

k kool yea...it was indeed the uppipe...the sensor also came off...so its running fine now...thx for the input...
