curious about this -

how did you cut it?
were you able to do that yourself?

I'm glad I saw this before I tried to put that pipe in myself.

I may just have my mechanic do it along with the magna flow resonator.

Any other little things to know about the install? Thanks for your help!

The cover is plastic, so I just used my dremel with a cutting disc

This is acurazine, where people can feel 2 whp from a pulley swap in a 3500 lb car, as it slams them back in the seat at half pedal. And where people measure a profound difference between aftermarket j pipes via seat of the pants. No need to quantify gains with dynos or time slips!

Ok, I'm done breaking balls. The pipe does look good.

Roffl.. bro this had me rolling.. its soooo azine though lol

Grand_hustle17

He looked at a picture on the internet n totally knew what gains the owner got n how his car drove though.... I gotta say thats the most amazing analysis and dyno ive ever seen in my life.... To the person who said that, i am also interested in what is the owners exact power numbers and 1/4 times based on where he is at n DA temps n all... If i pm you my mods can you tell me what mines are too?

I concur with most of this but there is nothing you can do to please everyone in the crowd....

ohh the dyno reads high, you cant make 10whp from an intake, you need to find a mustang dyno,well its not a 1/4 mile track, the track has a 34.4365456575 degree decline hence the trap is high


cant please everyone....I for 1 am in for dyno's but we know what happens on the dyno's as well....its very very easy to bloat numbers....just take the serpentine belt off and you have an additional 5-6whp to show for !!!


so lets just calm the fcuk down and wait for Marcus to post something up....

and yes by looking at the pipe you can "assume" the gains....here, let me give you an example, and please dont tell me you dont see a difference and cant assume which might gain in lower/higher rpm range


ATLP V1 and V2:


Labree:


ATLP V2 and V2R:

Grand_hustle17

well here is the thing, comparing the difference even if you bloat the dyno numbers up you still can say there was a difference in the bloated numbers before and after so hence the pipe still made more power..........

Im glad you posted that pic...... Where can one find that labree j-pipe?

I almost made a similar post. Was going to show the evolution of all current Jpipes on market. Looking at that alone you can see they all went to a similar design in their current versions. You saved me quite a bit of time lol.

If you're in the game long enough, you can already tell just by looking at pictures of all the different Jpipes that already is offered to us. Look at the dyno's Marcus has been doing, of all the hp and dyno's last year by 3 jpipes (XLR8 v2/ RV6 v3/ ATLP) Example: If you look at the ATLP jpipe, the shorter primaries is making a little more power in the upper RPMs, compared to the RV6 V3. The conclusion to building primaries all comes down to the length. Don't get me wrong, all of the jpipes out there make proven power, but some people want TQ over HP, HP over TQ, or a little bit of both. As I mentioned in there, it's a theory, just something to talk about and looking at it before Marcus comes in to give us more details.

To the person who said that, i am also interested in what is the owners exact power numbers and 1/4 times based on where he is at n DA temps n all.

For $hits and giggle$, don't modify an AUTO TL. At least get a LSD in there. If you want, I have one for sale.

iTrader: (5)

No sir...imagine (just saying numbers)

Stock makes 200
X1 jpipe makes 210
X5 jpipe makes 208 but since its new, it has to sell, so take the serpentine belt off and now it makes 214...guess which one everyone is going to buy !!!

Labree is a one of one pipe....I recently had the opportunity to buy it but backed out since for 5AT guys, you have to "make" it fit...



well glad I could help :P

but yeah for the most part, we know shorter primaries make more power up the band and longer makes more down low....a lot of people know XLR8 pipe is a good compromise since it makes more low end than ATLP (but less uptop) and less low end than RV6 but more uptop...

so I am not surprised that the primary length on the V2R look very identical to the XLR8 jpipe....where the ATLP trumps XLR8 is the merge....the merge looks a lot more subtle, the merge is 0.5" wider in diameter....I think this pipe is going to make more low end power than ATLP V2 and close to or more than XLR8 V2 and its going to make a lot more high end power being more free flowing....

As I said, I am in for dyno...the last comparo that Marcus did was awesome !!!

Grand_hustle17

ive been in the game waaay to long hence why im saying u cannot tell lol

bouncer07

Can't blame a Nissan Maxima VQ35DE guy who can't tell. Time to think like a Honda.

is it me, or is the same collector design used in all 3 versions of the ATLP jpipe? did Hytech design all 3?

wilztlxs

iTrader: (8)

Yes, Hytech designed all 3.

The V1 and V2 have a 2.5" collector while the V2-R has a 3" collector

Sonnick

Interesting. Wonder why it was only mentioned in relation to the last variation of the pipe.

Bottom line is, ALL of the Jpipes are great. They are all designed really well, have great merges and they all do their job efficiently. One thing people miss is that each Jpipe is going to perform differently on each car. One car with a 4" CAI and a 3" exhaust will have a different result with 'X' Jpipe than a car with a 3" CAI and 2.5" exhaust. There is not 1 BEST Jpipe for every car. Most people ask what the best Jpipe is, but there really isn't one. You need to take into consideration all of your mods and then decide.

What would really be key, is if we could get a dyno of a Jpipe on a CATLESS car. Every dyno I've seen is on either a stock car, or a car with a catback only. I think we would all like to see dynos of a car with full bolt ons (whether it be with PCDs or HFPCs) and each Jpipe. I would say more than half of the modded 3Gs on this site have deleted the primary cats, whether it be with the PCDs of HFPCs. I think a dyno showing the difference in power of each Jpipe on a car without the primary cats would trump all. Just my .02.

bouncer07

I want to see is that dyno chart.

" We spent over 10 hours on the dyno and invested thousands of dollars in prototypes in conjunction with Hytech Exhaust to come up with what we wanted to be the BEST performing j-pipe for J-series Honda and Acura V6 engines on the market."

Not sure if anyone else added v2-r midpipe upgrade to their order but my last status update said It's going to be another 6 weeks.

wilztlxs

iTrader: (8)

Might be just you

I'm hoping to place an order for the V2-R Exhaust in January or February.

How's the V2-R J-Pipe with your currently setup as is? I'm loving mines.

Mondo375

iTrader: (3)

we seem to have the same setup except for TB, crank pulley, exhaust and .3L lol. But I love it. Would definitely buy it again over the v2 any day.

Does the bend have the same clearance over the splash guard as the RV6?

wilztlxs

iTrader: (8)

I had to trim the splash guard a bit more compared to when I had the RV6

MrHeeltoe

iTrader: (1)

On what basis do you have for saying this at all? Hytech designed NONE of the merges on any production J-pipes ever. Their collector design did not show an improvement in the testing we did and would have greatly increased the cost of the part. So we did not use it.

MrHeeltoe

iTrader: (1)

All we currently have are pre-production test data. We need to assemble a dyno test where we can provide real production dyno data. It will come...eventually. It is a difficult thing to coordinate.

wilztlxs

iTrader: (8)

my apologies Marcus, just an assumption since you worked with them to produce the J-Pipe

sockr1

iTrader: (5)

marcus just sent you an email back about testing the jpipes (i was super busy for a while and have some free time coming up)

kingkong_dav

I won't be the test dummy. I've given Marcus 3 Saturdays that im off of work n still no bite. Now I think he's talking to sock1 about dyno time so I'm wasting my time n trying to be the lucky one

sockr1

iTrader: (5)

i emailed him recently with an open weekend and he said he prefers atlp catback so he said thanks but no thanks for now haha.

i have no idea who he has lined up

kingkong_dav

Ok I'm off this sat

MrHeeltoe

iTrader: (1)

This is kind of a crackup to read...

Posting here that you emailed me is not really necessary. All it does is increase the number of things we need to reference out there, which slows us down. But I can appreciate what you were doing here so thanks for the follow up!

We need time to coordinate things and unfortunately that means we need extra time to reply to emails. We'll tell you when and if you are out of luck...in email. Just the same, thanks for your patience while we did reply back.

Any updates on the product.mondo or wilzrsx? How is she driving now.what improvements r very noticble

wilztlxs

iTrader: (8)

Love mines, feels great across the entire rpm range. I don't regret making the move from RV6 V3 to ATLP V2-R. It currently sounds great paired with the Stage 3 exhaust mod, but I need to get the ATLP exhaust to finish it off, its the last missing piece.

kingkong_dav

I didn't know you switched from rv6 to atlp. Is there any rasp?

wilztlxs

iTrader: (8)

No rasp, it's deeper and quieter

Vilex

Glad to hear! If you don't mind can you make a quick video of the exhaust sound? I have the stage 3 as well and a jpipe is probably going to my next mod, just hoping the jpipe doesn't make the stage 3 sound like shit lol.

With your jpipe n exhaust bottle neck do you think there r more room for gains or it is a good substantial gain as is

wilztlxs

iTrader: (8)

its great as is right now, but there is obviously more room for gains considering the stock exhaust piping is 2.25". the ATLP exhaust is 2.5" for the mid-pipes and the new V2-R Exhaust is 3" for the mid-pipes. The ATLP exhaust drops back to 2.25" at the mufflers.

kingkong_dav

I Wonder how much mondo is loving his jpipe. I read his piping is back ordered 2 months. I really want this jpipe. I'm being cool calm and staying away from clicking the order button because me heeltoe think I should wait for him and the dyno
