OK. I am looking at getting some headers in hope that it will give me so better low down torque. I am looking at getting the XForce 4-2-1 headers from the sponsor Racing Nation. I realise that 4-2-1 configurations give better low to mid end torque than 4-1 but at what revs would the improvement come in?

Am i optimistic in hoping that the xforce 4-2-1 headers will give more toque around the 2000-5000rpm. I rarely hit VTEC so i would want all the improvement to come in below 5000rpm, preferably the lower rpm range the better.

So are the xforce 4-2-1 headers any good?

I already have a Mugen twinloop catback exhaust, so would there be any improvement as well in getting a high flow cat as well?
