Secondary high flow metal cats

e.n335 · 04-25-2008, 12:16 PM

Hi,

After installing RISS catted DP's my next planned exhaust modification will be the secondary cats. Is it feasible to gut the stock secondary cats and install high flow metal cats in the OEM housings ? Anybody knows a good brand and can recommend specific metal cats ?

I appreciate your feedback.

Cheers,
Eugen

why would you do that? Why not just replace the secondary cats?

It should look like OEM to avoid the efforts for removal / installation in case of regular inspections.
