Hi Efren,
You would be better served going to SELOC | Lotus Enthusiasts Club in the UK, as here in U.S.A we only have experience with the S2 version.

Hi, My name is Efrén and I write from Spain.

I have a Lotus Elise s1 modified with collector series, de-cat and iron exhaust suppressor of Janspeed:

Preparación de mi lotus elise de principio a fin ( ojo modems ) - ForoCoches

The sound is strong but I'm not convinced.

I want one exhaust with sounds better, with great sound quality, regardless of weight or effectiveness.

I am among these:
eliseparts
2tubular
larini sport
larini club sport
komo-tec

Whay has better sound quality of all these?
