Alfa GT 3.2 Decat ?

Any ideas as to the benefits of removing the cat under the car and who would be able to do the work. My car has been lowered quite a bit and I have scraped the undertray quite a few times so any help will be appreciated

Decatting is not going to alter the scraping issue, unfortunately. I actually have Arqray equal-length stainless front pipes (expensive), and they actually have scrape marks in them!

My car is reasonably low; got a photo of yours?

I haven't decatted, but I have changed the main undercar cats to high flow 200 cell/in^2 versions. Honestly, didn't notice any change in performance; though sound changed a bit (for the better). But I did notice decent improvement with the equal length FPs.

Changing the manifolds to catless versions would be kind of nice, but expensive and a lot of work. Not worth it to me, personally.
