Exhaust question?

1. Originally I was eyeballing the Akropovic system myself. It looks really good, and I knew it was coming from a reputable company. The cost is really high, but so is HKS, another brand a few people around here have. The biggest thing about the Akropovic that kills their cost is having to ship overseas... Most vendors stateside get people by saying the cost is including shipping. Which is a win for us...

The best feature of their exhaust in my opinion, is the option of the Carbon Fiber tips. They look GREAT! I've seen/heard it in person, and those tips are very

2. Based on images of the Evolution (full cbe), they do have what appears to be 12" resonators in the mid pipes. An H pipe section as well vs FI's X pipe design. The slip on muffler section will use your stock midpipes/resonators.

3. If you're only putting on the cbe, a tune is not necessary. If you plan on doing other breathing mods (HFC's/TP's, Intake, Pulleys, etc.) then a tune would be warranted.

4. The CBE paired with stock cats will still sound very quiet at idle and cruising, and will have a better sound when you give it gas. I have heard the full system with TP's and I must say it does sound Very aggressive, but there is a lot of rasp in it. If you were to get Resonated test pipes, this might combat that and just give you a very exotic sounding exhaust. And FI does make Res TP's. It would be worth it to get the full system because you'll see the most gain from it. If you just get the slip on axel-back, you won't see a good hp gain/$$ balance. It would be purely for a slightly different sound and looks.

5. If you plan to get headers in the future, there are two varieties. The Shorty header (Stillen, Nismo) will need to be paired with Stock cats, HFC's, or TP's. Long Tube Headers, (FI, PPE) will Not need cats or TP's as they will run the full length and bolt directly to the mid/X-pipe.
