Custom Exhaust Systems at JTK Remapping
A new exhaust changes how your car sounds every time you start it, and the right one lets the engine breathe and make more power. We're authorised dealers for Milltek and Scorpion, and fit them professionally at our workshop in Dungarvan, Co. Waterford.
For anything off the shelf can't do, our in-house fabrication service builds a custom exhaust system to your exact spec. Every system is dyno-tested and matched to your car and the sound you're after.
Why Choose JTK for Your Custom Exhaust?
You get the choice of 2 of the best-known names in performance exhausts, Milltek Sport and Scorpion, alongside our own custom fabrication. Whichever you pick, it's fitted here and checked on our dyno, so the exhaust adds performance as well as noise.
Our custom systems are made from premium-grade stainless steel with precision TIG welding, and the branded systems fit as the maker intended, with no cutting and shutting.

Our Custom Exhaust Services
We build and fit everything from a subtle change in tone to a full performance system:
Single Exit Exhaust Systems
Single exit exhaust systems offer the perfect balance of performance enhancement and subtle styling. At JTK Remapping, we specialize in creating bespoke single exit systems that complement your vehicle's aesthetics while delivering the perfect sound note.
Twin Exit Exhaust Systems
Make a statement with a precisely engineered twin exit exhaust system from JTK Remapping. Our twin exit systems combine aggressive styling with optimized performance, perfect for those seeking both visual impact and enhanced sound.
Cat-back Exhaust Systems
A cat-back system replaces everything from the catalytic converter back: the pipes, the silencers and the tailpipes. It changes the sound and lets the engine breathe more freely, without touching the catalytic converter. We fit cat-back systems from Milltek and Scorpion, resonated or non-resonated, and build custom ones for cars the brands don't cover.
Straight Pipe Exhausts
For the ultimate in performance and sound, our straight pipe exhaust systems deliver uncompromised flow and aggressive acoustics. Each system is carefully engineered to maximize performance while maintaining daily drivability.
Valved Exhausts
A valved exhaust gives you two cars in one. With the valves closed it's quiet enough for an early start on the motorway, and with them open you get the full sound when you want it. Milltek and Scorpion both make valved systems for popular performance cars, and we fit them here.
An Exhaust and a Remap Together
An exhaust on its own changes the sound and frees up a little power. Add a remap and the engine is set up to use the better flow, and a performance exhaust is part of every Stage 2 remap. We measure the car on our dyno before and after, so you see what the pair is worth.
If you drive a V8, from a Ford Mustang to a Dodge or Chevrolet import, the exhaust is where the sound starts. Press Enquire Now and tell us what you drive and the sound you want.

Perfect experience from start to finish. Very easily dealt with. Got my mk7 golf r remapped difference is like night and day. Can’t thank the team enough
So I got a hybrid turbo from muchboost installed in my Mercedes c220 and was advised to get a custom remap on a dyno so I contacted John got it booked in and he also offered hydro clean as an option and It was worth every penny I couldn’t believe the difference it made plenty of power and ticking over like a dream thanks again
