right iv got a scorpion exhaust system on a VTS, which manifold should i go for ?
should i go 4-2-1 or 4-1 ? and i was lookin at janspeed but then i have a scorpion exhaust .. iv heard GMC 4-1 heat wrapped are the best to go for but i thought id ask on here and hope a few of you know abit more then me ,since i have friends who have used raceland and not felt any gains and a few others,so wonderin wat people got and if it made much difference
Thanks
