Question about the secondary cat delete
So I have the AWE track exhaust. Love it, but was looking forward to upgrading the sound now that I’ve had it on for about 2 years. Had the car up on the lift at a shop to do a secondary cat delete but they said it was already gone with the new exhaust. Was not expecting that. So my question is does the track exhaust already remove the secondary cats? I didn’t know that.

Respectfully disagree. The car sounds amazing and not fart-canny at all. Should have come this way from factory.

If you have the awe track exhaust you DO still have all four cats, unless a previous owner did a secondary cat delete. The awe track starts after the cats but before the h pipe, hence "catback exhaust".
I had a shop make me an awe track type setup (as mentioned is really only straight pipe stepped up to 3 inch) and also did secondary delete at same time. It sounded good and was fairly loud at idle and low rpm, but it almost seemed to get quieter/ not as loud as I wanted under throttle & WOT, so I ended up putting my stock exhaust back on and went catless downpipes. I'm finally happy with how it sounds. To get these cars to make some noise under load, you really need to do catless downpipes. I think even a high flow catted downpipe setup would also almost be as loud.

Ahhh I definitely see them now. Yeah the first shop I went to didn’t know what they were doing. Went to a performance muffler shop and they’ve got me scheduled to get it done tomorrow 👍

I ran into the same issue, lots of places won’t touch cat deletes. One of the shop owners directed me toward this muffler shop I had previously called however and said that’s weird because he got his done there last year. So a lightbulb went off and I drove there and asked in person. Voila, getting it removed tomorrow. So I think it’s just a liability thing, they won’t say they do over the phone but they will in person.

I'm hearing this new EPA thing going on makes it harder for people to get second cat delete.

Hey I'm thinking about getting the awe track exhaust but its basically a straight pipe. I occasionally drive between cities (4 hour drive) and I was wondering how is the drone on the highway? I just don't want to get a headache when driving on the highway cruising at 2.5k rpm
