Call the local shops around you and explain to them your situation, or better yet bring the car / parts into them. They will be able to tell you what parts you need to supply or what they have in stock etc. etc. vtecgsr98 suggested a 2.5 inch, and he just did a similar setup so that is probably good advice.

 

what i want to know is, can i just drive over to the "muffler/speed shop" with my 3" thermal and 3" test pipe and ask them to make me a DP? or do i need to prchase flanges and piping?????

 

do i need to order SS piping for them to make me a DP?

 

3'' downpipe caused spikes and creep on my itr with greddy kit. Had to switch to external wastegate to solve the problem.

 

did you have a 3" exhaust set up also?

 

3'' all the way

 

what setup are you currently running? also how much was it to custom make your DP?

also did you have to supply all the materials (SS piping, flanges?)

did you fab the external wastgate to the greddy manifold or did you buy a new manifold and downpipe and wastegate and use the greddy turbo?
