Disadvantage on 2.5inch all the way exhaust?

[rhys.l]

I think all the info in this thread can be summarised as follows:

-Daily driver, minor bolt on mods -> 2.25" or maybe 2.5" with bottlenecks

-Performance car, all usual bolt ons, cams, tune (or planned) -> 2.5", true 2.5"

-Serious enthusiast seeking big power with major supporting mods -> 2.5" + (up to 3"?)

Or that's what i think

the disadvantages in my mind would be the extra attention due to the noise and potential grief from the cops..
as long as you can deal with that then go ahead and do it.

Ye i noticed that...mostly since i had to take the exhaust off to cause it wasnt connected properly. Thought i might go for a run without it...louder then a formula one car...

Anyways, in return! Good gains mostly at high rpm's its a good good gain! this is with a stock cat too.

Nothing resonators can't fix.

I have a 3" exhaust and it has been tested by the pea and it passed. Obviously there may be a loss of power but would be minute.

All exhausts can be quite if you want them too.

Another question that should be asked what are the advantages as you are paying more for a larger exhaust on a stock engine there probably wont be many gains from 2.5 to 3"

No advantage, except future-proofing if major mods are planned. In most cases, no advantage.

Yer agreed unless you plan on major mod such as forced induction but your paying more for materials when its not needed

I personally think, 2.5" exhaust is good from little bolt on mods to engine internals (i.e cams, pistons etc).... <-- 3" & you will make more power in the high rev range & will lose some down low.
3" if you are going forced induction.
