HKS exhaust help
hi all, i have a HKS Hi-Power exhaust on my car which i want to take off and replace..now, ive been looking on the net and as far as i can make out this exhaust is a 3" cat back system can anyone confirm this?? i was under the impression it was a 2.5" one but i cant seem to find a 2.5" system listed anywhere. also im unsure if i have the standard downpipe fitted now either unless the HKS system narrows to 2.5" can anyone help please

Also,dont forget the HKS/Blitz exhausts have different angled flanges, the bolt holes are at 9 and 3 oclock,whereas the standard flanges are at,i think, 7 and 2 oclock (been a long time since i ftted a standard flanged system LOL)

If you have a 3' decat downpipe then there is no need for the donut gasket,you can simply use a flat gasket , i know as i have fitted/taken off a blitz, and a vortex to replace with the std oe exhaust. in the last 4 weeks

sorry,didnt make myself clearer,as i was going on the other thread by the o.p
If you have an HKS OR blitz full system and want to use different back boxes,this is what i meant, the HKS and Blitz Mid section has the 9 o clock 3 oclock backbox/midsection joint (not on about d/p flange)
so,if you want to fit another backbox to the hks/blitz midsection,you cannot fit say, a standard vortex backbox to the hks/blitz mid section (apart from them being 3",the flange holes are different)

Pic of my old HKS system (backbox/midsection joint) you can see the flange joint just below the Diff
