Cat-back or full system — which do I need?

Cat-back swaps everything from the cat back: a bit more sound, slight weight saving, mostly cosmetic and aural. A full system (downpipe + mid + cat-back) actually changes power, especially on turbo cars where the downpipe is the choke point. If you want noticeable gains, the downpipe is where the work happens.

Will it be too loud for the road?

Victoria's stationary noise limit is 90 dB for most passenger cars. Reputable brands like HKS, Invidia, and Akrapovic build to pass. Track-only race systems don't, and we'll tell you when a product crosses that line.

Will an exhaust change my tune?

On a tuned car, yes — and you'll want to re-tune to take advantage. On a stock car running stock ECU maps, modern exhausts are usually fine without a tune unless you also change the downpipe. We'll tell you when re-tuning is worth it.

Can I supply my own exhaust?

Yes. We'll check it on arrival to make sure it fits and the welds are sound. Warranty on fitment applies only to parts we supply.

What's the lead time?

Usually 3-4 weeks to book. Bolt-on systems are normally same-day. Custom fab takes longer and we'll quote the time when you book.

"Revzone did a great job fitting my cold air intake and tuning my VB WRX. Car is much more responsive down low and is perfect for a daily driver. Jeff was extremely helpful and insightful through the whole process and I would recommend to anyone looking for a tune of their car!"
