FEELER: Intake Mid-Pipes-Please read
^^ What would be really cool is if you made a true 3" midpipe, with a 3" ID that way people can have the upgrade without having to tune or get a new TB. This will be especially helpful for those that have a bunch of mods but dont want to tune anything much past stock. 

Yes Tubing is measured on the outside and piping on the inside. I learned that from the start looking into this and calling dozens of metal supply places..
I do have 3 inch ID here...as the walls are .125. relatively thick but its the way to achieve 3 inch ID. its here. its made. its now for sale

I dont know anyone local with a cipher....any volunteers?
I went this size as its a relative upgrade..and equivalent to previous products from berk as far as i know.
Also, if a .08 inch (2.03mm) jump isnt relative...then it should apply to TB as well??
72.6 to 75 mm upgrade. Its practically the same difference. This SHOULD net a difference...open to any tests i can do. All i have is an ELM module? dunno if that measures AFM? think thats right term- also thinking thats what you want me to measure over stock

now. AFR is a good comparison so we could see what a difference the added diameter is making. Timing is relative to MAF flow, which is related to AFR. In any case, this small upgrade might be complimented well with Z33 injectors.
^^ I'm guessing a gain should be there, but probably a very small one at best. I'd also venture to say you won't see any gains doing this on a stock engine, but one with I/H/E mods and/or especially a tune this will give a gain.
Id say this logic applies to any aftermarket intake setup (best being complemented with headers/exhaust to see larger gains). As with other products; i am not selling a labeled HP increase here. I think ppl determine that they want to run a cone filter setup and have a sri; opposed to factory. This Mid pipe allows them to do that.
5mm (.2") make a difference in TB I.D! So I'm sure there will be a difference and if intake valves oversized by .020" can make a difference so will a few tenths of an inch of intake tubing!
Thank you for seconding that. Exactly my thoughts as written in post #84.
Its gotta net a difference. Granted its not a 3.5 or 4 inch intake . Its an upgrade over stock- Ideal for those looking for an intake with minimal other plans for upgrades

Be open to asking a question whenever you like. Id be more than happy to answer what i know the answers to..
Were merely discussing the size (diameter) of the intake tubes. Measurements interchange here and there thru threads between inches/mm.
Thanks Stillwell. Hold it down for me when i dont get to it in time

that will be $60 an hour sir. Thank you. Lol
Thanks feeler and fishtale and I do offer them as described in a full sri format as well as a quasi cai setup that places the intake behind the headlight. Without the use of the stock maf housing etc. Mine are all 1 piece bolt in affairs that allow you to take advantage of the lrmaf theory or just get a bit more oomph with the 3.
Sorry cleaned up a bit. Try me agian. thanks!
yes, There are pics in the FS thread. I am also adding them here as well. Powder coated units are still not in hand. I get them wednesday....
On other notes; please HELP me help you. I have ordered 2 maf adapter at this point...NONE of them line up all 4 holes to the maf housing. I spent a while dremeling holes today but ran out of light and time...a link to the perfect match would help.
I was betting high on the vibrant part # 1997. its a no-go as well. HELP
pics per request posted here as well. I relocated my battery today (injen wai method; to make room for my massive 7+ inch aem dryflow) I will have an installed pic tomorrow

^^ Excuse my multiple color couplers and zip ties pipe. I will be fabbing a simple aluminum band to hold it upright and still. There you have it gang. Finished product.
Went on a drive as soon as i could....SCREAMS. is all i can say. My overly massive filter of choice and BPi velocity stack make it SCREAM. Like an angry mob of elephants in a stampede. "very trumpet" like in this setup. Howls. screams. blares. all words describe this at wot. At idle no difference. at normal driving minimal difference.

Just installed my midpipe from Deep today. I must say i was very impressed with the fit an finish! The welds were clean and solid. P/c was flawless. I had a MAF adaptor with a bs autozone air filter and was still using the oem helmholtz piece that connects TB to MAF. After replacing with mid pipe it really was impressive! It screams after 3k rpms! I know this isnt a new mod and it has been around since the beginning of time but i thought id give my .02
