It doesnt have to be true dual, no. Alot of people prefer the larger diameter single systems for supercharging (nismo, etc).
I'm still debating which zorst to go for, I'm concerned with S/C, HF Cats, and a Nismo, it may be too loud, I,m still very keen on a Miltek exhaust as I know from past experience that (ecu modded) you will get a performance gain and plus they are a bit more subtle, Lomoto, did't you have one?
Yep I had one , very nice item probably better made than the Nismo I only swopped it because a Nismo came up at a bargain price The Millltek on reflection sounded spot on.. the Nismo is now too loud with the Hi Flo cats, induction kit, Kinetix Plenum I have fitted as well
Bit boomy on the motorway, isn't it
He He,.. just a touch Dorian.. the only plus side is it makes me keep it below 80mph on the M1
