exhaust size

[tRipitaka]

I think if the exhaust go too big , it will loss the back pressure. and then is just like you can hear the exhaust sound but the car not moving...^.^

another backpressure statement..

i think save ur money and do something else. Adding a 2" exhaust isn't gonna all of a sudden turn ur car into a rocket. It just feels faster due to the noise, simple as that.
SAVE UR MONEY AND DO SOMETHING BETTER WITH IT !

my 2c.

i agree man but if you have already made up your mind about doing it don't go any larger than 2"

Yeah go 2" either press or mandrel bent. Although going mandrel isn't going to make too much of a difference...

1.75"-2.00"

[_FeRiO_]

I have a D15b myself, i had this same debate. In the end i went 2.25, which found was bit loud, but it went alright.

Well, i had installed a 2.25" pipe for my D16Y1 EG5. And i find it leak toque badly from 0-3500rpm. At those rev, the car just feel like not responing to the push in gas. Worst if you change gear in those rev. It feel like take a while for the car to get going again.

But once it pass about 4000rpm, the ground speed & engine speed dose go up quicker.

But Most of my time is driving in the 2500-4000rpm range so that slow feeling really kill me. Me is changing to a 2" pipe soon (When i have the money) & hopefully it will be better.

Got me think reading the above forum, should i do 2" or 1.75"?
