Need a custom exhaust with maximum clearance and trick factor? So did Hunter Witherrite and his super cool boosted 240. Stainless oval tubing makes both possible. We loved the way this complete system turned out. From the downpipe we modified to the Your Trusted Source! muffler. As always, lifetime guarantee on all our systems. Reach out if you have any questions, or if your project is next!

Austin’s mustang in for some well needed through floor sub frame connectors. We removed his old connectors, and installed a more serious approach to reducing chassis flex. This now allows us to land a proper Rollcage to a solid foundation which we are also installing soon. We hope you guys have a great time at your upcoming drag n drive! Thanks again for the repeat business on one of our favorite Fox body’s.

Look us up if we can help you with your build, or if you’d like to come check out our current projects!

S2000 came in for some tubo rework and kit correction throughout. Added new exhaust housing with V-band, reworked his downpipe, added a removable front crossmember, and corrected all boost path. We love being your go to guys for leveling up your project, so thank you for choosing Flipside Customs for parts and fab on this one AZ!

Martin back with a new project and a hit list for us to tackle! We first thermo-coated his headers and Y pipe, then high temp wrapped everything up. Then we built a custom SS back half system that included a muffler for both date nights, and getting rowdy with his troops. Dual tips finished the look he was after and we love the end result. This car rips!! From Corrado’s, to MR2’s, and now an LS swapped BRZ … Thank you for roughly 15yrs of loyalty and repeat business Martin! 🍻

Another round of upgrades for ._.the._.crayon F20 powered E30. Reworked engine and transmission mounts to include poly bushings. Upgraded rear end to include secondary mount kit with poly bushings for both ears. Lastly, some well earned track maintenance. Thanks again for making us your first choice for fabrication and track prep!

Tony’s 1989 Range Rover is getting more attention in all the right areas. Custom cut flanges, custom collectors, and full SS test pipes complete round one of his plans for this awesome time capsule.
