It will not work on a stock exhaust as it's a different connection to axle back. It will potentially only work with TD backbox. Sent from my SM-G970F using Tapatalk

These are all the rage on the other side of the Atlantic but if you ask the main tuners here , Mark -abbey, Mike -Tuning Dev, Adrian - fensport, they will not really vouch for them but only Ace (and Rogue (Very similar design to Ace) and JDL old manifold /TD (very similar design). Not sure why the other manifolds don't give same results here, different fuel quality, different weather, tune etc. Unsure. Have a look at this video just for reference Sent from my SM-G970F using Tapatalk

All the best. Just 2 more days to go. Put your dyno chart up and am sure you will love the drive back home. Sent from my SM-G970F using Tapatalk

As@deacon has said, there are really only those 3 manifolds that have proven ability to eliminate the whole torque dip. Rest all do it to certain degree and not the best result here in the UK. You have done it the right way in some ways , now with an exhaust + manifold, you have the least restriction and can get the best outcome of an NA tune. With 1 cat , you will pass your MOT in the initial years for sure. Not sure if it has a long term risk as the CAT weakens. It is a good investment and if someone wanted 1 mod that gives the best NA performance gain, then this is it. Sent from my SM-G970F using Tapatalk

As they say , every little helps and impressive that torque went up by 5% . I might be tempted to go down that exhaust route. How much extra did Mike charge to retune? Sent from my SM-G970F using Tapatalk

Did you get the car back on the dyno and get a retune after the cat back fitting? And if yes could you please share your before after. Sent from my SM-G970F using Tapatalk

Yes it is fully compatible with stock and you will get all of the power gains and eliminate the torque dip . All you will miss is the UEL beat which is easily done later. Sent from my SM-G970F using Tapatalk

Some additional advise, If your car is stock and all you are doing is cat back exhaust, you can go for a louder exhaust like TD res, not super res and still have subtle enhancement. When you go with a catless manifold, res becomes loud as sound insulation by 1 cat is lost and people advise super res. Turbo makes your exhaust generally quieter than stock as well, so think through whether this is your only mod or the beginning of a journey and where you want it to end up making it future proof.

Thanks. Looks really good. Makes it look like a Volvo screen, if you just ignore the buttons and knobs! Did you need loads of connectors to get it to work or simply plug and play?

The head unit looks massive. What make and model is it? Is there an audio quality change just with the unit or did you change the speakers or add an amp? Sent from my SM-G970F using Tapatalk

Welcome and happy motoring Sent from my SM-G970F using Tapatalk

Thank you Jeff. It's very interesting. Auto Express, Evos sister company has in this weeks magazine done their tyre test and Asymmetric 5 come in at 3rd place with Falken Azenis and Nokian Powerproof getting number 2 and 1 respectively. Sent from my SM-G970F using Tapatalk

Did they include the new premium goodyears( recently launched)in test? Sent from my SM-G970F using Tapatalk

Finally. Well done for using carista and persisting. Sent from my SM-G970F using Tapatalk
