Re: Downpipe/Dump, 02/Wideband Bungs, 3" Exhaust Cutout *Need FAB Placement HELP*
 

---- I dunno what to do, run everything open and hope for god I never get pulled over and the cop checks for emissions ----

Or if I should continue fabbing and entire exhaust and work with my mechanical cutout and some ssort of reroute of my dump back into the exhaust

See i have basicly the same problem. my WB opens up pointing directly on the side of the block. so not only does it heat up the block but it lest nasty exaust smell get in the car... i need to do somethign i think i will try to run a pipe under the car but i wouldnt cut in to my DP.

just do that. and make sure that the pipe is facing downward.

In theory, it would be better to have the o2 bungs further down on the downpipe. It would also be more beneficial to have the wastegate exhaust gases enter the downpipe after the 02 bungs (from the sounds of what i think you want, id suggest you do it, smell and cops wont be as much to worry about) Just put the ecut our further back on the downpipe and as far as that goes, i really dont think its going to matter if the dump is before or after that. just keep the design simple so you dont have to much fabbing or leaks to deal with.
