Looking for Exhaust Tips Solution

2161 Views 11 Replies 5 Participants Last post by  BKL
So a few weeks ago I bought a 2015 Sling with a Hahn Turbo and Magnaflow Muffler (I absolutely love it BTW) - The Muffler dumps right to the floor in front of the passenger footwell (I will try to post a picture) with that said the exhaust fumes (and HEAT) are killing my wife. I tried to contact Hahn for a solution of the exhaust and they said they don't have anything open for me plus not to mention they're in FL and I'm in MD. But I was wondering if anyone has any information or a resolution on adding tips to the side (Kinda like the Hahn side exhaust) to help route the exhaust up and away from the floor and hopefully aid/prevent and or minimize the exhaust fumes exposure in the cabin.

Thanks in advance for the help.

The stock exhaust dumps in the same place as yours and many people have the same problem. I think it is caused by your windshield. Most windshields cause the air to go over your head and then it goes forward because of the vacuum created by the windshield trapping the fumes in the cockpit. I bought a Madstad windshield which is designed to prevent this and have never had a problem. I don’t have a turbocharger. I have headers and a ceramic coated muffler.
As Jerry D said, a stock muffler and exhaust is in the same place. I don't have any engine mods as my stock 2017 SL is plenty fast enough for me and I don't like loud. However, cabin heat, especially for the passenger is a well known issue. I didn't see it coming and found out real fast that riding on an 80+ day was intolerable. I added a full cabin carpet/mat kit as an insulator and added a real hood vent in place of the plastic fake vent to let engine heat out. These mods alone made a HUGE difference in cockpit heat. It still gets warm inside so I am considering adding some more firewall insulation and am investigating cabin venting. Airwings don't fit my ripper windshield.
The ceramic coated muffler I put on is supposed to be cooler than the stock mufflers and it’s not very loud. It does make the exhaust note a lot lower and sounds good. To be honest, since I put it on I haven’t been out with my wife on a hot day so I can’t say if it’s cooler. I can say that coupled with the headers it gave me a wider torque curve,
Thanks for your input!!!! The whole “Vacuum” issue has also been on my mind as I think this is a major part of the exhaust fumes in the cabin but I didn’t want to spend over $500 on a new windshield and it NOT correct the issue. I wanted to replace the shield with one of those adjustable ones which will allow the air to pass from under (and over of course) and will keep the fumes at bay or at a minimum drastically reduce them especially while driving. I’m aware that the fumes might be present at stoplights etc but driving they should be expelled out the rear with the adjustable shield. With that said maybe I should refocus my efforts on getting a new shield instead of hacking up the exhaust on my Sling.
I think the Madstad adjustable windshield would solve your problem.
