NHP Exhaust System

[usaf-lt-g]

I'm likely to supercharge my boxster S in the coming month with the iA Supercharger. In order to get the most of the system, pretty much all the performance experts point to upgrading the exhaust system and the air intake.

In terms of exhaust I really like the NHP 3.2L Full exhaust system, which comes with:

Performance Exhaust Headers with 200 Cells Catalytic Converters

200 Cells Catalytic Converter Mid-Pipes

2 x U Bend Pipes

Performance Muffler

2 x Muffler Clamps

Gaskets and Hardware

Has anyone used or experienced this exhaust system before? I want a good performance exhaust system that will compliment the supercharger, but at the same time, won't kill my eardrums while crusing around town. Performance should be there when I call for it. From the soundbytes, it doesn't sound too bad.

Also, I've heard many people complain about "upgrading the intake system."

^^I would like to know too.

This NHP exhaust on ebay which the seller claims 'no Cabin Drone, unlike most aftermarket Mufflers for the Boxster the NHP Exhaust Muffler for the Boxster eliminates Cabin Drone.'

Looking at the design of this particular muffler its very similar to most other ebay mufflers for the Boxster and apparently ALL of them do DRONE

Just last week I installed the headers and the secondary cat bypass pipes. Not the exhaust though. I am still using the stock muffler.

The headers look like a complete copy of the Fabspeed headers. They fit fine, and the quality looked pretty good to me. They are made in Taiwan and quite a bit cheaper than Fabspeed.

I just wrote up a pretty comprehensive review on the NHP muffler, just check this forum for it and you should have some good answers.

cheers!
