eisenmann exhaust question

parachute · 08-19-2006, 11:24 AM

Recently I became very interested in it.
I tried searching, but I still have a couple of questions.

1. How much gain in HP?
2. I read somewhere that the OEM exhaust has a valve that helps the car start, what will happen without it?
3. How much did you guys pay for it?

I'm not interested in the catback system for now.
I saw a video, it sounds sweet

I don't believe anyone that has the exhaust has dyno'd it yet, best is maybe to contact Eisemann to see if they have an official figure and dyno chart. My guess is <10 RWHP.

You wont get much from just a exhaust. You might gain a few horsepower here and their but i really doubt it will make a HUGE difference. Most people just get it for sound

I don't even think you will get any HP out of it. Unless your going headers back. The horsepower gains come with removing cats and resonators.

I have the full Eisenmann system and I can tell you it is well worth every penny I spent on it

From just the muffler, you really can not expect any sort of serious HP gains from it

The sound is simply amazing

I HIGHLY recommend it!
