Jb4, exhausts, ams ldp and other bolt on questions

I currently have ams bolt ons in my garage, hex,cai,ldp and coolant expansion. I am not ready to ecutek my car yet, Im thinking of running jb4 for the meantime. My question is should I install my ldp,hex and coolant exp first with jb4, I just read that CAI won't offer any benefit until im tuned. I am also planning to replace the exhaust system with either ark [email protected]$1300, or FI CBE or HKS both at $1800 I think. Is it worth it? I almost got 3" mbrp last week but heard more modification is needed otherwise it is loud af and drony. Right now I have helmholtz only. Ecutek and getting hpfp is not on my budget yet plus I will wait when Im out of warranty. What are your opinions folks? Im running on stock RS with just helmholtz and afe air filter.lol it is a little better compare to the laggy full stock but still laggy.

Exhaust first - biggest bang for the buck, and not just CBE, but also LDPs, too. Then add the HE to prevent heat soak. Install the JB4 at anytime during the upgrade process.

I'm a big fan of the FI LDPs & CBE - performance, quality, and awesome customer support. FI is a small shop, and collaborates with [email protected] for the Ecutek tune, so for future-proofing, this combination produces great WHP & WTQ #'s for the VR30 platform.

downpipes (even lowers) and Y/mid are all relatively cheap for the gains. Don't need to spend $2k on exhaust. Heat exchanger is excellent, no need for expansion tank. Skip the intakes. JB4 works well as a substitute until you're ready for a full tune.

i already have all the ams bolt ons including their lower downpipes, im torn between ark grip vs fi.ark Grip is helmholtz resonated like what i have plus it is currently 100 dollar cheaper. So i guess ill skip the Cai install for now and get the either exhaust system and get jb4. Thanks man

btw I forgot to ask you, can you recommend me a substitute Y and Mid pipe for the stock, rather than me buying the full exhaust system. plus I'd like to keep my infiniti helmholtz but if the the price of getting the mid and y pipe is close to the price of Ark grip, prolly i'll let it go. the ones I saw are the tanabe y and mid pipes, idk if it is really just for rwd, I presumed q60 rwd and awd are the same when it comes to the cbe part. correct me if I'm wrong
thanks

The Megan Y is what most use and its cheap at ~$100. The Tanabe mid is what most use and is ~$400.

i'm lookin at both tanabe y and mid, I can't find any info whether this is compatible with awd and I'm picturing it in my mind and i looks different when assembled over the stock. do you know if we need to make adjustments when installing it, compare to the other direct bolt on ones. like FI,ARK and HKS?

I can't speak to AWD, but I know my RWD Q50 let the Z1 full catless downpipes bolt to the Megan Y to the Tanabe mid to the stock muffler with no issue.
