Thinking of upgrading exhaust
Looking to upgrade exhaust on my 2015 and was hoping for some feed back on Borla vs Magnaflow.
Any help would be appreciated

I went back and forth with them both until I heard the Corsa Extreme's. The build quality is outstanding and I got them for les than $700. Just my opinion though.

I talked with my exhaust guy who does my fabrication stuff for me and he said 3" is a waste on a stock car. It removes to much back pressure and kills performance. Unless you have a lot of headwork cams and intake it really doesn't help. I just had everything custom built x-pipe back with mid mount mufflers and went with 2.5" and id say thats about perfect on a stock motor. Now granted i have a 4.6 but i still don't think the stock 5.0 puts out enough to get any benefit from it. He also said he just did a supercharger on a Camaro with 3" and it was not making the power it should. It all depends on your goals with the car and what route you plan to take your build.

I have the Borla S catback exhaust w/the black tips. I love it. It's loud but not so loud it will get any attention from your local's finest. It has the 2.5" pipes all the way back. Perfect match for the Coyote 5.0 My 2 cents.

3" catback on my 15 gt showed dyno proven 5 peak hp over stock and 7-9 ALL along the dyno curve
On the same dyno, same day, same hour with multiple pulls to prove it.
Added 1 7/8 stainless works headers and got another 35 peak hp and along the curve too.
Fabricators usually know very little about what actually makes power
Does he have a dyno in house? I'm betting 100% no.

5 HP is not detectable by the butt dyno and 7-9 requires a pretty sensitive one.

I had a 3" Gibson catback installed on day 2 of ownership and my wife INSISTED that it was too loud. Now I have a 2.5" Ford Racing/Borla Touring/black tip exhaust that works for both of us. Yup...the 3" didn't do too much except on the high rpm, and the FR/Borla 2.5" is a lot better at the bottom end, where you use it the most in daily driving. I just wish the FR/Borla did cost so **** much!
