!!!UPDATE!!!

After last weeks disappointing dyno numbers it bothered me that my car was getting such low numbers (179.2). After talking with a few people I decided to remove the Neuspeed exhaust. The reason I choose the exhaust first is because I just had to unbolt everything. Immediately I took it around the block and my friend said that he felt a noticeable difference.

Well today I took my car back to the same dyno. Surprisingly I got 197 rwhp. Nothing else was changed or modified in anyway with the exception of the exhaust.

I do not know what is wrong with my scanner. I will update the pics when i get a new scanner.

Please cut and past the pic AND remove the _ (space) after the "h".

This is a comparison with my max numbers last week and today.

I am in no way saying that the Neuspeed is a bad exhaust. I was very satisfied with the sound, looks, and I thought it increase my power by a few horsepower. Maybe it is because I am at such a high altitude. Maybe the first day was just a bad day for a dyno run. Maybe it was bad gas. I don’t know.

What else could have caused my numbers to be so low the first time?

I plan on bolting back on the Neuspeed later this year and see what is causing such a power loss. Just wanted to give everyone updated on my situation.

N/A cars need backpressure. Was the newspeed larger diameter? Did you retain the cat converter(s) when using both setups? What kind of muffler does the newspeed use compared to stock? Is it straight thru?

Congrats on getting some HP back. :)

Well, I am sorry, but I WILL say that it is. Any product that is designed to make horsepower and it takes away 10%, is worthless piece of crap!!! I don't have any personal experience with this product, but I would be writing a letter and including your dyno charts to NOspeed if I was you.
