Is your carbon fiber real?

All of our products are made from genuine carbon fiber, not hydro-dipped or vinyl wrapped. We source high-quality materials for each piece, and every product is constructed using industry-standard methods including dry carbon for specific high-performance applications. No corners are cut. No filler materials.

Absolutely not. None of our products are drop shipped. Every item is manufactured at our dedicated facility and shipped to our Chicago-based warehouse, where it undergoes a full inspection and quality control process before being delivered to you. We also offer a selection of custom designs created in-house that are exclusive to Insignist Motorsports — ensuring you're not just getting generic parts passed from one supplier to another.

What’s the difference between dry carbon and regular carbon fiber? Why is dry carbon more expensive?

Dry carbon fiber is lighter, stronger, and significantly more expensive to produce than wet (gloss) carbon. While wet carbon is layered with resin and cured with a gel coat for aesthetics, dry carbon is cured under vacuum pressure in an autoclave — the same process used for Formula 1, aerospace, and race-spec builds. This makes it the premium choice for anyone who prioritizes performance, weight savings, and structural integrity.

Is everything on your site in stock?

All of our products are always available to order, a lot are in stock and others are crafted to order, entering production shortly after your purchase. Because we’re a growing business, we balance warehouse space and customer demand, so some orders may take a little longer to fulfill. That said, we maintain an 'In-Stock & Ready-to-Ship' section, clearly displayed on our homepage and in the navigation menu. You can filter by BMW model and instantly view parts ready to ship from Chicago. We’re transparent with our customers, and you can always check your order status by emailing insignist.com@gmail.com or using the Contact Us page. We typically respond within 24–48 hours.

Yes! We want you to have your item as soon as possible. Items listed in our Chicago warehouse under 'In Stock – Ready to Ship' usually ship within 1–3 business days. If it's crafted to order, it enters our tracked production queue and ships when ready. You can always request updates as your order progresses.

BMW G80 M3 / G82–G83 M4 eksosanlegg

Enkelt 3,5" mellomrør med lik lengde + valgfri ventilert bakaksel (rustfritt stål T304 eller titan grad 5)

Oversikt

G80/G82/G83 er en fenomenal M-bil – lydsporet trenger bare å ta igjen det tapte. Vårt enkle 3,5-tommers likelange midtrør gir S58 den karakteren de fortjener uten at det kreves endringer i den originale bakre delen. Legg til Valvetronic Designs ventilstyrte bakaksel for enda mer tilstedeværelse og kontroll.

Dette systemet er kompatibelt med originale nedløpsrør eller frittflytende frontrør, og er konstruert for å levere en høyere, raffinert tone uten motorstopplys.

Lyd med nedløpsrør med fri flyt:

Lyd med originale nedrør:

Hvorfor det fungerer

- Design med lik lengde: Balanserer eksospulser for en jevnere tone med høyere frekvens.

- Enkel 3,5" midtseksjon: Optimalisert flyt for forbedret respons og kraft gjennom hele turtallsregisteret.

- Modulær design: Passer til originale eller ettermarkeds bakre seksjoner; oppgrader til vår ventilerte bakaksel når som helst.

Lyd og kontroll

- Med originale nedløpsrør: Merkbart skarpere, mer engasjerende tone uten drone.

- Med vår ventilerte bakaksel (valgfritt): Firekammerlyddemper og OEM-ventiler gir dagligkjøringshøflighet i lukket tilstand og en aggressiv motorsport-forsprang i åpen tilstand – med et knappetrykk.

- Ingen CEL: Systemet er konstruert for å unngå motorlamper.

Konstruksjon og alternativer

- Materialer: T304 rustfritt stål eller ultralett titan i grad 5.

Ventilintegrasjon

Installasjonsnotater

Kompatibilitetsvarsel (V3-systemer)

- V1/V2-komponenter er ikke kompatible med V3.
