size/length/taper

what design /measurements for the reverse cone bro ?

thanks for the info guys, ill be getting them made at the coast, and yeh it wont be done dodgy exhaust shop press style, I'm unsure about my exhaust ports will have to measure them and its in a ke70 bud :) and i was thinking of going mild steel to avoid cracking

personal preference.. ill be going for 4-1 rather than 4-2-1 so i don't need to worry about 1-3 & 4-1 being connected. however some say 2.5" tubing down to a 2.5" cat then 2.25" the rest of the way. and the tube length at 28" does that sound good ? @littlered could you measure yours (length) and give me a rough idea how long yours are ?

iv done a fair bit of research, most headers that are cheap have a fair few shitty reviews, if I'm going to spend the money i might as well do it right. I'm currently running those shitty trd copy ones. most proper tuned length ones cost over 1k anyway so might as well get them built ?

hey guys, I'm getting some custom headers made up (tuned length) with mandrel bend and exhaust (with hi flow cat etc) i just need some help in what size tubing i need and the thickness ? they will be 4-1 headers, however I'm unsure to what size/thickness to get for max performance. this is what my build is 4age 20v toda over sized high compression forged pistions C/R 12:5:1 H beam forged condrods ARP head studs ARP crank studs Kelford 194-C racing cams Toda racing adj. cam gears Full head reco port and polish Supertech 1mm over size valves Supertech racing vavle springs Tomei crank caps TRD 0.8mm multi layer metal head gasket TODA timeing belt 1zze Coilpacks ITB'S (trumpets) thanks :)

yeh iv emailed fat fitment i heard they do it. see what they say, my lil bro had some bloke from the coast come do his e30 beemer and did a mad job so ill see if he does it still,

haha i have wheels that fit, but not enough dish :( haha iv got money to spend, the thing is its overdue for a respray etc .. so i wanted to get this done before. i don't mind paying a lil extra to make her look better, I'm not gna spend cheap money and get a cheap job, one thing iv learnt is you get what you pay for. :) thanks for the input lads :)

mmmk theres a bloke selling weld on guards for 150 they are 70mm to fit 15x10 -5 .. but I'm a noob when it comes to welding, as far as i can tell its alot of work cutting the current ones out (inner and outer) then re welding... is it a bitch for bolt ons aswell ?

nice, did you flare the fronts too ?

yeh i think my ride height is around 75-80mm... i will be running - camber on the front. and i am leaning towards bolt ons on the rear, but unsure whats what on the front in terms of clearance :/ :(
