Hey guys, recently scraped (lightly) on a speed bump with my 2024 GT with Kooks LTH. I hear some grinding noise from/close to the engine bay. I’m guessing LTH maybe touching the ac line. Any idea on how to fix this noise?

Hi there - drove from Denver CO to Austin TX last week and as soon as I entered Texas got pulled over by State Troopers twice for no reason within an hour and got warnings saying I changed lanes without using turn signal, my license plate was covered more than 50% and I was speeding little...

Hey Guys - for past two weeks, after every car wash the taillight on the right side is ON (for about 10min) even after locking car. This wasn’t case before. Is there any water leak happening here that’s causing this issue?

Hey Guys, I recently installed a borla Atak catback exhaust (active valve)on my s650 GT. Sounds amazing and no drone. But few days ago I noticed the exhaust tips are sticking together on left and right side is about to be same. Worst thing it’s starting to rattle now and I’m not able to clean...

Hey All, I know some of you might’ve done better. But this is my first time driving in snow with “all seasons”. Was fun and little scary at same time cos of no traction and car was drifting. Thankfully the roads were closed so no oncoming traffic. Waiting on the winter tires!!!

Hi All, As winter is round the corner now I’m planning to get set of winter tires for my S650 mustang GT. I heard good reviews about Nexen winguard sport 2s. I have a base GT with all season tires - 255/45/18 and planning to get 245/45/18 on winter tires. Will this setup look bad on car? This...

Hey guys, As long tube headers aren’t legal here in CO I’m planning on upgrading my stock exhaust on s650 Mustang GT (Active exhaust) by getting Borla cat back. As S type has more deep tone which I guess would be perfect if I had long tube headers and Atak is more louder/raspier haven’t heard...

Has anyone in CO installed long tube headers on their s650 mustang GT? Lot of performance shops I call say it’s illegal to install them in CO area. Any work around apart from me installing it by myself?

Hi All, New member here. Got my S650 few months ago. Also, got H pipe and resonator delete. Sounds much better now than stock. But now I’m outgrown this sound and need more I’m planning to go with Borla S type axel back but it’s close to $2000. Is there any alternative exhaust sounding similar...
