After doing some research I have decided to go with HKS Hi Power on my 1998 gs400, My only question is..... The HKS website says the 120/60 mm is reccomended for the car however Im wanting to get the 170/75 mm and delete resonators , Does anyone know If this will work or what Mufflers I should get?

 

are you going for sound or performance?

why do you want to do with dual 3" piping and delete your resonators? Do you know how loud and annoying your car would sound?

 

I've got Hks that i haven't installed yet for my 400, I think I've heard some sound clips but ill reserve judgement till after I put it on.

 

Not to mention no power gains, and possible loss of tq..

 

the only thing i could think of is the excessive rumble of the V8. some guys dig that

 

Well I wasnt certain about size etc or what was compatible. I would be installing it for sound and performance so im assumimg that its really loud with resenators deleted so I will leave them on, im going to be sinking alot of money into the car and just need some input on do's and dont's. So if anyone has any suggestions please let me know.
