Hey! I just wanted some opinions on an exhaust.. now I already have an Greddy SP2 exhaust on my IX but I've always been a huge fan of the HKS Hi-power exhaust.. Should I keep the greedy or invest in the HKS???

 

its all personal preference bro! I think that they are bout the same power wise, you could sell your greddy and make up the difference to buy the HKS.

 

i have the hks hi power on my car and i like it, i had it running with the cat, and now catless, it sounds really nice without a cat, loud, but not bad. i can have a normal conversation without screaming. with the cat on, it was cool. not very loud at all. hope this helps!
