Hi all

just trying to find a decent 60mm decat to buy for my car ! Can't seem to find any ! Loads of 70mm ones . Can I use the 70mm ones on a standard exhaust system ?

Thanks for any help

 

Stock is 2.5" isn't it (63.5mm)?

It's not really good practice to mix diameters. Particularly the decat. Ideally you want to stick to 60mm, the same as the collector on the manifold and centre section.

Invidia De-Cat Exhaust Test Pipe (2.36"/60mm) - Honda S2000 | eBay

Here is a 60mm pipe. I'd shop around as they can be had for less. Failing that a custom exhaust shop would knock one up cheap.

 

Ok that's great thanks

think ill order the invidia one , as I've had a few of their exhausts and been very impressed with the quality . I'll also order a o2 spacer .

 

I just ordered the 60mm £60 one off eBay - is even resonated .

 

I've got one for sale if your interested? Send me a PM. From memory its a Japspeed resonated decat. I took it off when i fit my 75mm catback so wanted a larger decat

 

This is the one I have - releases 6bhp without any other mods .
