I'm running FLP's and off-road pipes through a Corsa catback. The car is the basic H/C/N20 (100 shot) variety. After doing some digging it seems like most people are showing anywhere from 3-15rwhp gain with a cutout but those numbers seem to be off a stock car. I got one as a gift and haven't put it in yet but it is a single, manual cutout that will go in the I-pipe near the axle.

Anyone have an idea if it would be worth it on a more modded car and any guesses on gains?

you already have the catback so your not going to see gains of that much, you might get some more sound out of it but its probably not worth the hassle

So you think the Corsa is no restriction then? I have seen posts about guys with some brand of catback that ended up choking the system and figured that all catbacks must be the same to some extent.

Before my cam swap, my dual cut-out give me only 2 RWHP.... After my MS3 they give me 13.5 RWHP and 10 RWTQ !!!!

aftermarket catbacks are usually more free flowing then the stock system unless you get like a flowmaster or something

you can add a manual if you want, there inexpensive....(40 bucks installed on mine, 14rwhp)

I'm expecting 50rwhp over my flowmaster(it came with the car ).
