hit me up on aim I may have an answer not sure though would be easier to explain on aim and ask numerous questions!!

 

Dude cmon, turbo is still better than supercharger, just learn abotu everything before you install. IMO anyone who installs a turbo without a boost gauge needs to go back to the drawing board and rethink why they are doing it in the first place. Boost responsibly, nough said.

In response to your problem, probably an exhaust leak if its as loud as you said. Unless it has any metallic or banging sounds, its most likely exhaust, and just for future reference, up pipe, down pipe, etc are all part of the exhaust system...

 

the bolts on my downpipe came off gasket is gone anyone know where i can buy a gasket for the downpipe?

 

O'riley, ive had this problem more than once....the one that fits goes to a late 90's mirage....just ask to see it before u buy it and make sure its the right size.....then this sucks but i would take off the headers and do it all right again other wise it will need to be done again later down the road....good luck.

 

You can get one from any local auto parts store. All you need is a standard 2.5" or 2" (depending on what size piping you have) exhaust gasket for 2 bolts. I picked up 2 from Murray's when I did my turbo install. They cost $1 each.
