have the prl hvi coming in soon then i'm thinking prl downpipe since it’s 3.5 in compared to others that are 3 in. also the prl flex fuel kit. wondering if anyone is running this simple set up so i have an idea of what my numbers gonna look like. forgot to mention im on phearable stage 3 and possibly going stage 4 flex fuel after all mods.

if your staying with the stock turbo a 3" dp is more than sufficient up to about ~500hp or so.

you don’t think i can get a little more power from the 3.5 inch dp with a tune or anything ? every horsepower counts lol

No. The stock turbo is not large enough that its flow is being restricted by a 3" exhaust. I highly doubt you would see large if any gains. If you are simply looking for gains you would be better suited with a catless dp.
