So mocking up my downpipe now and just curious on Turbo RA owners opinions on how necessary a flex pipe is in the downpipe.
I understand the reasons for having it and all but curious on the amount of engine movement if its really necessary or if its just a good idea.
Stock mounts but they are fresh (for those not following)
I will be making solids very soon ....

 

you need a flex pipe, lol

any minor movement that isn't taken up by the flex pipe will be on bolts, hangers etc. you can get flex pipes on ebay for real cheap...and they're not too bad...
