Hello all, I currently have a standard exhaust apart from a ninja box on it. What can I do to make it loud and mean, still with good emissions?

On a 2003 blob

Thanks in advance :)

My exhaust is the same but I have a classic. I'm going to get a centre section that eliminates the centre resonating box so that should help make it a deeper louder rumble and release a couple more ponies.

Thats what I was thinking, what would ineed for that? Is it likely to be 3 inch or 2.5?

I'm going for a 2.5 inch because I don't intend on putting a larger turbo on.

Is that the difference then? I.e. Will 2.5 fit standard unless I upgrade the rest to 3 inch

I'm not sure if they fit standard. But the centre section should bolt to the downpipe. I don't think it'll matter what size the actual pipe work is. If you have a look on Scooby world it should give you an idea of what parts you'll need. And I'm sure someone with a more extensive knowledge will be along to help.

Thanks man very helpful :)

As long as the flages match at either end you'll be ok, some taper for the flange, so it will be 2.5 at the downpipe join then go to a 3" section. If you've got a 2.5" backbox just get a 2.5" straight through section it will join at the cat peffectly

As stated above, 2.5" is standard size
