Morning,
The Porsche failed the MOT on emissions yesterday. As it just scraped through last year, I have already replaced Lambda's MAF and the rather worn PSE boxes for nice secondhand Cargraphic ones. So, we think that the CATs (Sports 200 cell ones I bought seondhand from ELA a few years back) are done for.....
With the option of going for either an X-pipe design, or stay with the original crossover design, I'm looking for others experiences to help me decide.
The main issue is to pass the MOT.
Secondary is to enhance torque and sound if possible, but bearing in mind it already has 200 cell cats, I'm not expecting much.
My concern is whether the X-Pipe design experiences a loss in Low to Mid end torque. If it does, can you get round that by re-mapping? Is there a marked benefit of going to an X-Pipe on the 996.1?
I know the 996.2 has a better cylinderhead and more sophisticated ECU, so really these questions may relate better to the 996.1 in particular.
Any help or opinions welcome thanks.
