Does anyone know if the pipes that come with the greddy exhaust PE are larger in diameter than the stock pipes on a GS300. Thanks

LexusRules

yes they are much larger

GS400_PUSHER

yes much much larger!

So lets say the stock piping on a gs300 is about 2.25 in dia. Would the Greddy pipes be around 2.75 or so?

Ken, are you considering getting rid of the Ltunded and getting the Greddy?

LXOGOOD

No, I'm just trying to get an idea to see if it's worth changing my stock pipes to a larger diameter. My muffler guy said that the exhaust pipes under the car are fine and that I really don't need to go up in diameter. But if the Greddy pipes are larger, than it must be for more HP right? Does anyone know?

more HP and louder I bet.

the GReddy flows a bit too well for our GS3 cars... i chose it because A) i was un educated and B) i have turbo assperations.

i loose a *LITTLE* low end power since the system was designed for the GS400/GS430.

Overall i gain more than a i loose but i love my GReddy and wouldn't trade it for anything... well maybe a fujubitsu exhaust if someone offered me one.

the GS300 piping is 70mm and i think stock is like 50mm or 55... just guestimating... go under ur car and measure yourself!

Thanks Sasha....

Hello All,


The stock piping on the factory system is 55mm. The piping on our PE system for the GS is 70mm. i must also point out that the system was designd for the GS 400. You will gain on HP on the top end, but low end will suffer. I would also like tell you that we are planning to come out with an all new EVO system for the 98 and up GS's.

GS300's you mean?
