Off road Y versus SLP Catted
Off road Y versus SLP Catted Quick back story car is a 98 with about 110k miles I got my heads and cam buttoned up and tuned last June and the guy said the fuel pump may be maxed out...Stock pump. I agreed and he said when I replace the pump bring it back he'll dial it in and squeeze a little more out of the car. Well as the summer went on the car started to have pump issues as I tucked it away in November understanding I would get a pump this winter. I went ahead and ordered a drop in replacement from the WS6 store that has the Racetronix 255LHP pump. The car currently has an SLP Catted Y and a Holley 92 throttle body. I have a ported FAST 102 I acquired from someone local and I was thinking about buying an off road y. Will it be worth the money on the Y and will i see any impactful gains from changing this set up and getting it back on the dyno to spice up the numbers?
SLP has offered several Y pipes over the years one for manifolds and others for long tube headers. What is your current exhaust set up?
Manifolds or headers?
If manifolds & SLP stock replacement Y pipe with cats then all of that exhaust should be replaced.
Long tube headers & a Mufflex 4 inch Y pipe makes for an excellent set up.

doing the trap door (this is my third fbody lol) the pump I got is rated for 600 hp, even at the crank I'd be shocked if it were pushing over 500 tbh.

I would do the ORY if you don't have a sniff test, I am not a fan of cats. But you might regret this if the rest of your exhaust system is already very loud or rasp-prone. If you have a quiet-ish muffler, I would go the ORY route especially for a heads/cam car.
edit: in my mind removing cats will net HP considering there is no more restirction, just not sure how much and if its worth the 200ish for an ORY
