hey guys, i dont like the civic rasp of the helix test pipes to the stock exhaust. which exhaust other than the new greddy one gets rid of the rasp and adds a unique sound. i'm also hoping that when i go for emissions, all i want to do is remove the test pipes and put the cats back on. im thinking the injen straight tip or the nismo. keep in mind im also looking for a decent power gain. lookin at 10hp minimum.

P.s. i want it to be lighter then the stock exhaust, because the stock one is just fat. the helix test pipes are 20 lbs lighter combined then the cats, so thats good. which titanium exhausts out there add good hp.
