anyone using the jba cat forward headers? have they given you any power ? the stock manifolds look so restricted it's ridiculous! don't want to go for longtubes in jersey inspection is to much of a hassle!!!
Im running them but as for power i added the headers the same time i added the blower so i cant say if they did anything for me. I saw someone dyno 12rwhp with a blown car when they added the jba's. I wouldnt get them on a N/A car unless you plan on adding a power adder down the road. Its just alot of money for not too much power. Also if your going to go that route, make sure you get the jet hot coated headers.
