Hope you don't mind a simple exhaust question ?

[308tr6]

I have tried to read through the endless posts, but it is tiring and I am lazy. So...if you don't mind.....
For the 2.0 L Turbo if you keep the stock cat and just do the Mach 5 race spec or similar others does it give you a decent sound upgrade? I know that is subjective, but I don't like loud just to be loud, just want some increased volume but more importantly hopefully more like a low rumble sort of vibe.

Im told that it's mostly the downpipe . I ended up getting both the downpipe and race back.

Downpipe is the key. Cat-back dun do much for volume.

Thanks for the replies, so no one has even done the catback only? Seems unlikely, but I get it once you're messing with it might as well go all the way.

Still I think I would be interested in a subtle to moderate change.

There are many people who have done catback only. There is an improvement but its still underwhelming if you are an exhaust tone connoisseur. People have installed GRP, Aerie, Mach5, Milltek, etc. catbacks. More than likely though, people have only heard the stock exhaust and then whatever aftermarket exhaust they installed only. So they cannot necessarily comment on differences between more than the one aftermarket ehxaust.

Also, there arent as many people who have done downpipe AND catback combo swaps.
I have had stock, then GRP Ti catback only and now GRP DP +Mach5 race spec exhaust. I really love the combo I have now but it is ironically still a tad soft compared to my 4C and its Magnaflow Corsa exhaust with stock DP.

Acceptable loudness and aggressiveness are so subjective so if you have a chance to hear comparisons in person, video clips are so hard to differentiate differences.

I can't wait to get more pops and bangs next year after remote tuning becomes available for my Inokinetic tune. I miss it from my 4C tune.

 

[308tr6]

Docron, I appreciate the full explanation. And yes I hope to get a chance to hear one sometime before I make a decision.. As much as I love the hooligan mind set of the tuner crowd and their 4 banger flame throwing fart cans, I just don't care for that tone, so trying to find some middle ground here somewhat above stock.

So I am going to sidetrack my own message here - can you give me the beta on the inoknetic tune vs JB4, that was the next "sorry I am too lazy to read a 1000 posts on tuning". Trying to figure this world out as well in a succinct manner.

Cheers

We have the same tune I can answer:

You send Inokinetic your ECU, it gets cracked, then the tune is placed on it, they mail it back, you reconnect your ECU.

yup, what Kaz said. Shinoo@Inokinetic tries to aim for that process to be around a 10 day turn around which is kinda crazy fast. Dont regret it at all, love the tune, smooths out the powerband, decreases the low end lugging and very nice amount of increased torque.

I didnt install my JB4 so I cant comment on any comparison between the JB4 and the Inokinetic bench tune. @Kaz has driven aggressively on both platforms and he has posted about his experiences about this specific comparison in other threads.

Presumably the Ikonetic doesn't impact the CPC and therefore the delayed manual shifts still remain?

 

[docron]

The delayed manual shifts are a TCM/TCU issue, not necessarily a CPC issue. But like the other bench tunes from what i understand, the ECU is tuned to the limits of stock CPC for now. once the CPC is cracked and the torque limiter number is adjusted in the CPC, more power and torque will be added.

It will be interesting when there is a good TCM tune to address the gearbox shift times.

Thanks for the info, so where does the Inokinetic land HP and torque wise? Is it one size fits all or some choices? I found the website, but it doesn't even list Emira (or at least I couldn't find it).

Oops, scratch that. I did find the Emira. I had a Lotus Exige 240 awhile back and I think I remember this guy from those days....

Why is this superior to the JB4?

Update your car to the latest software at the dealer the new TCU updates are better

Lots of research you can do, running a native ECU tuned is better than piggybacks for various reasons. In this case the power delivery is better the JB4 causes lots of CPC intervention you will feel throttle hesitation - the JB4 works well but it's pulling a slight of hand to make it work and the ECU does a better job.

The Inokinetic tune is the only choice available in the US, it's stage 1. With 93 gas you're probably 460-480hp? around there with about 480ft-lbs depends on how you calculate dyno and your fuel. There are no options the tune adjusts torque request and goes up the limit of the CPC making trouble. I think it's a no-brainer and should just be standard issue for anyone with an I4. Also the JB4 is kind of a pain to install you'll either have to remove the firewall or just spelunk upside down from the engine side with a long pick tool. Where are you based? There's one in Cali and one in Ohio

Ok I appreciate the info, that just saved me hours of sifting through threads! I am in SD, and that means South Dakota, not San Diego. Nothing is close to me!

Feel free to DM me and/or @docron if you have any questions think we are the only two so far with the tune, and I previously ran JB4 + methanol injection so have a good comparison
