I'm thinking of moving to a Spyder and if I get a stock one, I was thinking of just changing to the race headers to see if that would be "enough". My CS has the IPD Competition Plenum, GT3 TB, Fabspeed race exhaust and Cobb Accessport Tune done by Steve at Fabspeed. During those conversations, he basically said my existing exhaust setup isn't really doing much for flow since the headers are so restrictive. I'd hate to think about how loud it would be if I added the headers to this setup. This is why with the Spyder, I may do the Plenum, GT3TB and headers and keep the stock exhaust. What do you think about that?
Hey. Saw your post about Fabspeed race headers adding 30HP. Was that the only change made, i.e. Fabspeed headers with factory exhaust? Or was it in conjunction with Fabspeed race exhaust too? I have a 09 Cayman S with Fabspeed Race Exhaust but factory headers, hence the question. Thanks.
