Anyway, buy it. Rotrex it. Done.

EP3 with that power... torque steer not a problem then

[The Batman]

Torque isn't a problem for Hondas

[gaffer1986]

It does when you're in a low gear.

[The Batman]

the maximum torque on that graph is only 240lb

As I'm looking at changing my exhaust I have found a nice comparison graph on a ep3 with a standard engine running either 2.5" exhaust or 3" and you can clearly see the gains below!

8hp for the majority of the rev band... mega gain then!!!!

Imagine if you went 3.5

Be careful not to build a car you can't use anywhere.

It's not just torque that causes torque steer, power counts also. Cars can still be rapid with little torque depending on the gearing.

Remember guys this is on a standard engine whereas mine isn't...

So if I can get 20bhp more then I defo think it's worthwhile

I fail to see how a 2.5" exhaust can cause an 8Hp restriction on a meazle 220hp engine, (and then the restriction issues will show up more in high rev area.)

Think this has more to do with a scavenging pulse length effect of the different 3" exhaust...

[The Batman]

I'm surpised it adds the same low down as it does up top tbh Could only find a couple of comparison graphs not many people try both! The 2.5 will defo be better for sound and I could reuse my 2bular backbox then Ahhh choices.... life is hard

[The Batman]

Screw it im listening to the sound police and going 2.5" and will just take he telling off from cpl racing when I get it mapped Now I just need to see some bits out the garage or rob some grannies to pay for it Keep my standard backbox or buy a new repackable one.... hmmmmmnnmmmm

[CHILL Gone DUTCH]

It's probably got more to do with 3" exhaust sales God I'm getting sinical

[The Batman]

Cpl racing doesn't sell exhausts for Lotus's so is unbiased

[CHILL Gone DUTCH]

But they may get installs or "tuning " RR money

[rob999]

So is this a k24 bottom end? I've not been paying attention!!

[The Batman]

Lol they don't chill Mine is k20 you want to buy my old exhaust for when you blow yours up?

[techieboy]

He'll only want it if it's got crooked tailpipes.
