So I found a pretty decent exhaust leak yesterday on the corner and right next to it kinda under it. Could this be cuasing my low vacuum problerm and reson I cant boost ? Also have a leak on my downpipe but I would see why that matter in this case. Thanks

 

Anyone else have experience with this ?

 

hum..

 

exhaust leak wont effect your vac, but it will affect spool, power, etc. what manifold are you using?

 

GReddy ..Just found out about 4 of the exhaust manafold stud holes are stripped to **** ...Anything I can do about this ? Eaislly and cheap

 

ouch. timeserts aren't cheap or fast but would do a nice job of fixing this.
drill and tap for next size is probably the cheapest route but you may run out of room on the flange for oversized fastners.

 

I might try the tap and die set my friend has ...Hopefuly everything will go smoothly
