jrsc headers,exhaust

im putting a jrsc on a gsr and i have a 21/4'' magnaflow exhaust no headers yet and test pipe what would be the best thing to do with the 3... what headers go good with the charger and exhaust as well if i can keep the exaust...

jdm dc 4-1 or kamikaze header with 2.5 collector
testpipe/hi flo cat
2.5 exhaust system

the best thing to do is get all 3.

so the 2.25 magnaflow i have now will be no good? what if i got a 2.5 header with the 2.25 exahust? or would you say to defidently get a 2.5 exhaust which sucks cuz i just recently bought this exahust not knowing the size cuz i got a good deal on it. and the 4-1 dc are better then the 4-2-1 headers with the jrsc?

2.25 is fine. if you want the most out of your jrsc. 2.5 all the way is the way to go. concerning the header. you want the JDM DC, not the DC. the DC will do, but, many people including myself have ran either the JDM DC 2.5 or the kamikaze 2.5. the 2.5 is the way to go.

well said
2.5 exhaust kamikaze header and catco or random tech cat will be a great set up for a JRSC powered car
