That looks awesome, so if I understand correctly the pipes don't connect to the tips so what was happening without the plates was the reverb was coming back under the car into the trunk area but with the plates, it pushes it back out the tips.

I mean looking at the pictures that's how I understand it.

Correct, the plates help prevent noise from coming back up into the trunk area and force it out through the tips. I wouldn't say there was a significant reduction in noise after putting the plates on but the reduction is noticeable.

How hard was it to get the plates off the stock pipes?

Not very difficult using a sawzall with a blade for cutting metal. I put the muffler and pipe in a vice and cut through the welding and pipe on the backside of the plate. It scuffs up the back of the plate a little but I had planned to repaint them anyways.

Very nice I love it. My opinion much better than the wrap idea. I will be doing this weekend awsome, thanks

You may want to consider welding the plates to the u-bolts if you or a friend has a welder. Bolting like I did works but was kind of a pain in the ass drilling the holes in the u-bolt. I went to Ace hardware and got grade 8 1/4" x 1 1/2" bolts. You'll want to drill the holes as close to the bolt as you can so that you have room between the nut and the pipe to tighten.

I think a lot of the reason for the drone is that the Borla tail pipes don't have the plates on their tips that the stock pipes have:

I tried this guy's solution of wrapping the tips with exhaust wrap to fill the gap between the pipes and the factory exhaust tips:

Using this wrap (wear gloves):

Now the drone is gone and the cabin noise is reduced. Still louder than stock on the inside but at least I can have a conversation without shouting.

As for the slower feeling, I felt the same way at first, and also when I first installed an intake. It seemed like some low end torque had gone missing and it needed more throttle to get going. I think the ECU just needs time to adjust.

So does anyone know if those "plates on the tips" have a specific name? My cat back was added at the shop while it was in for repairs and they already scrapped the old mufflers by the time I had asked about salvaging these parts. Looking on-line for something similar or custom to replace it. Not too keen on jamming a bunch of fiberglass in the pipes. Any ideas?

Why the hell did they scrap them. They belong to you? Did you get some massive discount on labor?

Yeah that's pretty messed up that they threw them away. You could probably make them yourself if you're handy with metal. I'd combine the two plates on each side though. I dont think there's any reason they have to be two separate pieces. Another option is to get some clamp on tips I guess.

Idk - the new system was replacing the stock after my rear end accident so labor and part costs were already covered by insurance. The OG mufflers weren't necessarily damaged, but I guess they tossed them along with the bumper when they did the initial tear down.

Rather than fabricating something to prevent the drone, why not just replace the exhaust tips with some aftermarket ones that bolt onto the exhaust? That will also eliminate the sound from resonating.

Do you know of any tips that can both mount to the exhaust and fit into our lower valance like the stock tips do, without causing concerns with melting ( apart of the reason they arent attached to the stock exhaust piping ) and having to cut/trim the valance to make them fit?

I just ordered the Akrapovic tips. You do need to slightly trim the hole at the top get them in. There is a thread on here that outlines it all. Owners have said they have not had any heat issues in a year or more of ownership.

Here is the thread:

those tips look great (probably cost an arm and a leg...) but do they work as good as the plate would ?
I was leaning towards the wrap but I am interested in the plate option. who else has done it and can share their experience ? I am unsure about drilling and all that

They aren't too bad if you search for a good price. These will work as good or better than the plate as the exhaust bolts to them and exits past the diffuser so no more vibration under the car.
