Posted here from this thread. http://www.starquestclub.com/forum/index.php?showtopic=143256&hl=exhaust&st=0       I'm upgrading my exhaust because the 2.5 was too small for MPI. I knew it would be but it was all I had at the time. I'm starting from scratch with just some mandrel bends and straight pipe. I didn't want to have to redo it down the road so it's all stainless pipe with 5 V-band joints. Gonna be so much easier to take apart with V-bands instead of bolts. Cost me $100 fo

I'm in the process of ordering the pipe I need to fab up a 3 inch exhaust from my 3" dp back. Was wondering if anyone remembers roughly how many bends are needed . I imagine just a couple 45s? I'm doin some searches as well thanx.  

I can't believe there's no thread already started any way here's wishing all of you guys and you family and friends have a very good year in 2015 , may all your problems go away and your health be perfect

Ok so can i just run line from vac port on ovc pipe to wastegate? I have a manual boost controller thats junk and was wondering if the w/g will still work and only build factory boost levels with vac line direct to w/g from hardpipe to tbi
