What's up fellow G70 owners and admirers. I will post a pic or 2 of the car. What I need is some input on EXHAUST options? The car is awesome just needs deeper voice but not Barry White deep?

ARK exhaust was installed today. I've put around 200 miles on it already. A combination of twisties, country two lane, city stop and go, lastly interstate at 80/85 mph. Gotta love TX ? Noticeable difference in sound quality. Not fart can ! Very mellow. Unnoticeable at highway speeds. No cabin drone. Both Corsa and Borla could learn from ARK. Excellent build quality. Techs at Alamo were very impressed. They work on a lot of metrics and have seen some real garbage come through the shop. Think back alley eBay type.

No ! Re installed the OE muffler cans yesterday. Left the ARK mid pipe in place. Better flow based on design. True X vs the restrictive H crossover factory mid pipe. After the initial install, I took a 600 mile jaunt to burn in the ARK exhaust. A combination of interstate and back road twisties. https://www.onlyinyourstate.com/texas/windiest-road-tx/ Dyno showed a mid range power loss. Not what one wants. Max gain was at WOT ......... WTF, I don't drive that way. The cabin drone around town is insidious to say the least. It sounds like a bunch of pebbles in a can being shaken violently. Exterior sound is just as annoying. Total Honda fart can effect. Not what one wants from a G70. The irony is that the ARK mid pipe w/ the OE mufflers provided the best sound/performance combination. Oh well, live and learn. I've lost more at the tables in Vegas.

Glad my experience helped. It is sad as ARK has an excellent reputation. Their build quality is second to none. I would imagine it works great in conjunction with an ECU swap and dyno tune. With only 10k on the car, I'm not going to kick the powertrain to the curb.

Hey Ronrock, did you get your exhaust and intake fitted? Whats it like, performance gains? I am an Infiniti Q60RS owner with full stainless from Fast Intentions and intake kit running JB4 for extra boost but I'm looking to get away from the brand as they don't care about their customers? I love the G70 but wondered if I can get to a comparable performance level.

Hey Ronrock, sounds great - love to hear what it sounds like. I test drove the car again yesterday - love it but its nowhere near as punchy as my Q60 so I will need to add some toys and intake, exhaust and JB4 are definitely on my list. I believe my current JB4 will work on the Genesis(?) too just need to get another cable to connect it to the mgmt system. Haven't put it on dyne but running +6.5 on turbos plus mods = circa 100BHP+ to base 400BHP :)

So I'm curious what kind of gains you've seen so far.

Highly recommend the JB4 which is easy to connect and then with bluetooth and ability to quickly unplug is great for service - guys at Berger are great and forum is very useful. Although I do know you need new plugs but they do a kit now for G70 - 450BHP @ wheels which is quite an improvement :)
