Cheap easy HP gains?

I just installed these headers. They fitted perfectly & seem good quality.

Great value for money.

Woah that is a great deal. I might consider doing some headers especially for that price!

If you install headers, you will need to have your ECU flashed to ROW specs; if you don't, you're engine will throw a CEL for the catalyst (or lack thereof). Australian cars are delivered as ROW cars from the dealership, so they don't have that problem.

Also... Colo has emissions laws that mirror Commiefornia's so it may not pass smog inspection with headers/ROW flash. No smog, no tags.

I know of at least 1 Boxster somewhere in CO that is running completely cat free with a ROW flash...no problems with emissions testing as of yet.

Not only will a cheap set of eBay headers fail to give you any power or performance gains, there'll render your vehicle non emissions/OBDII compliant .

You cannot say that all of the cheap eBay headers will not give additional power. Porche's stock set up is awful from a flow standpoint. Eliminating the catalyst that is shaped like a coffee can with a port on the side would most certainly allow the motor to breath better.

True. But, once you've removed the headers/pre-cats and replaced them with a cheap set of headers that have primaries that are probably no larger than 1 5/8 in diameter along with the even more restrictive 600 cell secondary cats still in place, what do think you'll gain ?

There is no reason to keep the secondary cats. Mandrel bent cat delete pipes can be had for under $250; the install should take about 2 hours. There is a lot of unrealized potential in the 3.2 that was deliberately left untapped by the factory. Porsche's marketing dept likely did not want the lowly roadster beating up on it's older more expensive brother.

Have you ever tried going completely catless ? I have. There was a significant loss of low end power, not to mention CEL"s galore, along with the fact that the vehicle would not pass emissions/inspection testing.. I've spent considerable time (and money) over the years experimenting and testing various exhaust configurations for the 986 boxster. And, I can assure you that there is no easy or inexpensive way to improve upon and gain power over the oem system . I suggest that you gather some actual experience on the topic before making any more sweeping assumptions
