Cat and exhaust ideas on a 2.8
 

I need to replace one of my cats because its rattling like mad.
Looking for some ideas or replacing one or both cats
Maybe replacing my 2 into one exhaust to either the 2 pipe exhaust from a 4.2 or custom exhaust?

Tried putting a dent in them and tried a scew or two but I thing its come apart:mad:

I think one of my cats is rattling too. I dont know if its cost effective but I think I'm going to go for HJS cats again (there are cheaper cats out there). I had them on my old S8 and they were superb.

This place sells the ones I want for a ok price. I'll need two of these HJS-Nr. 90 95 0161
You could probably get away with 1 or two smaller ones.

The 0161 says up to 280hp?? Is it enough for an S8?

That's 280hp each - total 560hp

I did wonder lol. Schoolboy error!
