custom built 2.5" turbo back system,SS or Mild?

[supersyz]

Hi all my Seat leon Cupra is booked in for a new turbo back system and im unsure to go for SS or mild steel, there isn't much difference in the price but im told mild steel gives a deeper tone?

I was going to go for oval tail pipe too, does any1 know what size looks right on a leon?

I'm going for 100 cell sports cat too, would a de cat produce more power?

Hope im not asking too much for your advice on this but any help would be highly appreciated

Great advice guys, i was going for mild steel only as the guys there told me it will give a deeper tone.

Also Stainless Steel will last forever.
Go for either 100 or 200 CELL CAT so you don't have to change this for MOT time.
TBH I'd go for 200 CELL to be sure. If you want a freer flowing system couple this with an INA Engineering exhaust manifold

SS if you can but realistically how long will most of us keep our cars to notice.

as above... my mild steel has lasted 5 years and still going strong. If your going to sell the car within that kind of period. dont boher with ss
