Can someone tell me why the Greddy EVO II is not recomended for 04 GS300?????

 

maybe the size of the piping? to big for the little NA motor.

 

it's a 3" diameter piping so it would reduce backpressure too much and you'd actually lose efficiency on the motor. Kind of like why you would only need a 2.5" exhaust on an NA 6cyl but you'd want a 3" On a v8 or FI 6cyl.

 

I thought the diameter was 2.75"? Either way, it is not recommended, but you can get it for your GS3 if you really want to.

 

If it fits the 400/430 it will fit the 300. It could be because of the piping but that really shouldn't matter too much. Outside of that IMHO Greddy's drone like crazy on the highway, I rode in a buddies GS3 with a Greddy exhaust on a 4 hour trip to PA and back and I thought it was going to drive me nuts, def had to raise my voice to talk comfortable.

Have you looked in the Tanabe touring? It's still a full catback so you get more power but WAY less drone than the Greddy and a nice classy deep idle and refined tone while driving unlike a Civic with a fart box muffler droning away

 

i gotta say the greddy even on the gs3 it's really not civic sounding...surprisingly deep. Definitely loses low end torque though.

 

Well, I didn't really mean it sounded like a civic, but it's definitely more ricey than some of the other exhausts available.

 

So what is the best system to buy that will not have me sounding like a honda with a lawn mower engin in it ???????

 

Tanabe MT, IMO
