I'd be willing to bet very much the same. Same basic V6 block, same exhaust routing.

Any idea how much of a weight difference there is, if any?

Yes, I am interested in HP gain.

i'm guessings its not a true dual setup...still waiting

jjj784

perhaps, but consider the one liter difference in displacement between the two motors so it might not be the same. no beter way to find out than compare the two side by side.

i don't think there is a major difference in weight, both are heavier then I thought, but the HKS/OEM pipes are definely more free flowing.

anyone know if HKS are going to release their own version of this system?

jsquared

they are going to release an AM exhaust of their own. i talked to them the other day, they said probably by end of the year, so i guess that means december, but you know how specific dates are far from certain...

mlee21

aww man. thats when the promotionbuy of the lexus-parts HKS ends... hmm guess ill gave to gamble whether to go for one or the other. :/

Nicelex13

love the sound...would really like to hear it in person though...i had an HKS hyper on my is300 and loved it...but on the highway there was a drone...other then that its music to my ears

Have anyone ever regret of purchasing the HKS exhaust on their 2IS? I needed to know if this is the right exhuast for me, thanks

canadalexus,

how long did it take to order them? did you buy from Carson Toyota or your local Lexus dealership? How much did you pay?

Sounds nice but seems to be sticking out a bit.

Are there any fitment problems if you have the ground effects kit? I'm thinking of getting one for my IS and just want to make sure it'll fit ok.
