993 (RS) sports cat question
Having read the archives I have the following question;
I own a 1995 993 RS Clubsport. The car is fitted with Cargraphic exhaust boxes [mufflers] coded as CARP93ETS. With these I have the stock cats.
In an effort to save weight and gain some power I am consdering doing the following;
1. Using a cat-bypass pipe and retrofitting the cat before the annual MOT [roadcheck]
2. Alternatively fitting a 100 cell sports cat from FVD/Cargraphic/Dansk or similar
Question
1. Would I gain more power from the cat bypass pipe rather than using a 100 cell cat?
2. Which 100 cell sports cats do you recommend?
3.Would I need to do a remapp when replacing the stock cat with either of the twp options above?
4. Would I gain additional power from using Cargraphic or similar headers as well?
5. How much does te stock cats weigh vs. Cargraphics equivalents?
All input highly appreciated as I am looking to put in my order ASAP since the car now is out of its 6 month annual storage [due to cold weather...]
Some pictures of the car in question attached as well

I have the Cargraphic 100 Cell cats I bought from a fellow rennlister and I am very happy with them. I also have an Andial 2 deg timing block and with those two mods I get 251 RWHP and very good A/F ratios.
I believe I saved 10 lbs by using the Cargraphic. I have my notes elsewhere.

3. It would be advisable for max performance but not 100% necessary
4. not w/o further cam and intake mods
