just wanted to know if anyone has the HKS sportmax exhaust, pics of the exahust would be nice and compared to the rsr exmag and greddy sp2 how would they compare in sound, quality, looks, and performance. ive also had a hard time of locating this exhaust for purchase, i dont know if they even sell them anymore, they dont have it on the HKS USA website. any info and pics would be appreciated, thank you.
