exhaust

Anyone here have experience with running the Corsa Sport Catback @ Laguna Seca? I'm terrified of getting black-flagged for being too loud. I've seen some exhaust insert cones such as these: https://www.summitracing.com/parts/sum-629020 I'm not sure if it's snake oil or if there's actual DB...

I saw this video comparing most Ford Mustang GT V8 exhaust but still cannot decide. Any tips on the best Ford Mustang GT V8 exhaust? hp? sound? I would appreciate hearing from those that already upgraded their exhaust.

Used brand new but for $400. Trying to get rid of them ASAP. So price is negotiable.

So I used to have an ecoboost mustang and had a borla atak catback for it… I now have a 2020 5.0 and was thinking of using the borla mufflers as an axle back on my GT. I am going to get them custom fitted and welded into stock piping and add custom quad tips and also a custom x pipe.. do you...

Looking for any help. I have a 2016 Mustang V6 and just had my Roush Axle backs and a flowmaster x pipe installed at a shop. I had a second mechanic verify that the bolt ons are tight, but I’m getting a weird rattling sound/vibration on cold starts/idling and driving at low speeds. I have some...

Can someone explain the Sound Tube’s effect on the Exhaust? I thought it only affected the cabin noise, but there’s an audible difference at the muffler when I cover the sound tube hole on the intake and uncover it. If I cover the sound tube hole, the exhaust gets quieter, if I uncover it...

Just installed a Steeda H-Pipe on my 2020 GT Convertible with active exhaust. I was expecting a slight increase in volume, keeping the deep tone, no rasp, and no drone. I've got the total opposite. Volume: The start-up volume is extremely loud. Too loud for what I was looking for. Rasp: I find...

Was just wondering if anyone knew of a cat-back or axle-back exhaust system that sounds as close as possible to the stock exhaust note. I really love the way the car sounds, I just want it to be a little louder. I’ve seen people doing resonator deletes as instead, but I’m not sure I want to cut...

Hey! I just purchased a 2021 GT PP1 6pd last week and it came with the AE. After seeing how much an aftermarket AE system was I decided I wanted to try out an X-pipe to see if I would be satisfied for the time being. I have a problem though. I haven't received my permanent license plate yet and...

Really like my S550, but I wanna be able to switch the exhaust sound with a flip of a switch. Been trying to find the best options for electronic dump valves for the exhaust but can't seem to find many options. Has anyone done this setup before on the 2018? If so did you have to have your kit...

Hey guys, I've tried searching for this one but nobody seems to have this combo and I just want to get a grasp at how it'll sound. The combination is MAK/Lethal "Free Flowing Exhaust", X pipe, & Borla axle back (active). I'm trying to get a grasp at how it'll sound between the different modes...
