Do the secondary cats make a difference with the smell for catless downpipes?

Very much so. It basically removes the smell from what I've experienced on the cars that we've installed our catted system on at our facility.

Exactly!
The smell is completely gone with my HFCs.

Hey which HFC did you choose? And is there no drone with that setup?

I can't comment on the steps since I don't have one, but it's all about how you drive. Some people complain of drone with exhausts but they're driving 50mph in 6th gear.

What do you expect?

luca335i · 01-22-2009, 02:45 AM

No drone at all. My AA catback droned though. It does get a little louder after a few hundred miles but sounds nice

Why did you choose them over other HFCs?

Because I knew they would fit, and by doing some research, they work.
What other HFCs did you have in mind?

Makushr1 · 01-22-2009, 10:20 AM

Mr5-
I believe you have had CP-E as well. How would you compare the two? AE is a little too pricy for me, but I would like to hear your opinion between the two.

Mr. 5 · 01-26-2009, 03:45 PM

Sorry guys but I didn't have the time to take the video clips last weekend.
I also didn't have anyone to help me either. I really want to get an outside shot driveby as well.

Whoever's local that wouldn't mind helping with the video, then let me know.

I've never had the CP-E exhaust, so I can't comment.

Nick@aep · 01-28-2009, 05:29 PM

Anxiously awaiting tunnel videos!

Really? Could have sworn... Maybe I shouldnt drink so much.

Robmaster · 01-29-2009, 02:12 AM

very nice write-up!

too bad that the AE exhaust are not legal here in switzerland...

ramorendez · 01-29-2009, 09:37 AM

Hey, Mr.5, are your tunnel vids shot by the Long Beach Airport? I did a couple of tunnel runs there after unplugging the actuator and liked the sounds I heard revving through that tunnel

Regardless, can't wait to hear the tunnel clips!
