    exhaust question

    Ok, so I recently had an invidia n1 catback installed on my 2014 wrx (hatcback) and am now looking for a catless uppipe and catted downpipe. I will likely go with the full Invidia system, but Im wondering if anyone has experience with the TurboXS or GrimmSpeed downpipes. How is the build quality and reliability on the TurboXS compared to Invidia? What are peoples opinions on spending the extra money and going with the ceramic coated Grimmspeed downpipe?

    I havent heard of any problems with either brand. Why are you looking for a new up pipe? I believe after 05 or 06 they went with catless up pipes.

    if your gonna replace the up-pipe, you might as well get an EWG to go with it IMO. you wont get much out of an up-pipe with us late model guys....... if your looking to gain with an exhaust part besides the down pipe, i would suggest equal length headers. now theres a good gain right there.
    2013 WRX sedan - MODS = pretty much every bolt on besides a bigger turbo.

    Yup, what they said. Adding an aftermarket catless uppipe to your car will do nothing performance wise. Save up your money and do a uppipe for a external wastegate. Just know that you will also need injectors, fuel pump, wastegate, ebcs, pro-tune, and might as well throw in an aftermarket manifold too if you go that route.

    If you throw in the manifold and injectors, might as well do a tgv delete and air pump delete while youre in there.

    I.e. just get a DP and youll be just fine OP

    Oh and how do you like the N1? Is it the dual street?
