Comparing between a new twin 2.5" or a second hand 3" twin looking at putting in a 4" Dump and a 5" cat

Currently running in the 12sec mark and would like to nuch the 11's

Yet to fit a 12 pound actuator understand I will need a tune no matter what I get

Look forward to your reply.

What exhaust do you have now?

Either will be fine for 11s, not sure which would soundbetter, what brands are you looking at

3" singles flow worse than stock IIRC

Ild go the twin 3" for future mods although the fit would have to be tight?

I have 100% stock turbo and a manta 2x2.5inch, just ran a PB of 11.94 @ 120mph. 317rwkw, 17" street tyres (KU31s). Oh yeah 15PSI boost.

Warning - it drones from 1300-1900rpm. I'm looking into replacing one muffler with stainless (I bought the mild steel exhaust) to save headaches when towing at 100kmh.

Have heard good things about the Manta twin 3 but couldn't afford it! Wish I'd saved....though I don't like the idea of having to have turbo work done as well as mentioned by ratter! So guess I'm glad I didn't!

Dunno about the 3" single flowing worse, my brother changed his from stock to a single 3", and his making 330rwkw atm.

That can be made on stock exhaust though.
