I'm just in the process of an engine rebuild and while I'm at it I'm looking at an MOT passable sports cat downpipe. I'm looking for a 1 time purchase so don't want one off ebay that states that they can't guarantee an MOT pass. I'm sub 400hp btw with a current hayward and scott system on my type r.

Any ideas?

 

My classic japspeed sports cat has passed me 3 years in a row now

 

Your best going for 200 cell if your worried although I'm running a 100 cell Ninja sports cat on mine, it passes every year but needs to be warmed up before hand. And as mine sits in the garage most of the time it struggles.

Although saying that, my mot guy pointed out I have a slight blow from the centre pipe and this could be the reason why it struggles.

If you don't know the difference between 100 and 200 cell, basically 100 cell is more free flowing but needs warming up more than the 200 cell cat which from what I'd heard doesn't.

But with the power your going for 100 cell might be best.

 

I have a classic sports cat id be willing to part with ,, make a offer

 

I ran into a 2nd hand Miltek about 16 yrs ago (jesus really!), still good
