i was thinking about getting this but wanted to know how much whp you would get from it with the v3 j-pipe????

 

There are only five pair currently in circulation, so it's doubtful. I have them and the car is noticably stronger everywhere in the rev range. If I had to guess, I'd say 10-12 whp or so. That's on an otherwise fully bolted 6MT base though, that had 900 cell cats from the factory. The Type-S, in theory, should see lesser gains going to 200 cell cats, being that they have 600 cell cats to begin with.

I wouldn't base this purchase exclusively on a dyno reading anyway, unless the runs were done immediately before and immediately after the install.

 

I'm kinda new at this so correct me if im wrong but I thought the RV6 V3 Jpipe deletes the 3rd cat so how could u install the HFC?

 

There are three cats total. The two primary ones bolt directly to the heads, then to the j pipe. The third one is after the j pipe, and is eliminated by Richie's j pipe or can be replaced by a straight pipe when using the stock or another after market j.

 

Just to clarify, when I said 10-12, I meant just from the HFPC's themselves. With Richie's V3 j pipe, probably closer to 20 total.

 

They are talking about the pre cats that comes off the head not the third one thats further down the exhaust stream.

 

ohh thanks. So HFPC or PCD > RV6 V3 Jpipe > Catback. Which one is better the HFPC or PCD?

 

Its personal preference but the PCD itself will gain more power as it is a straight through design whereas the HFPC still has a less restrictive cat in the way. One is louder and so on. This has been explained before.

 

yea more raspiness out of the pcd's

 

so if pcd give you a little more hp what the aprx. # you would give them?... mine are in the mail now!!!

 

PCD with stock catback would yield 15WHP. PCD with no restrictions would yield 20-25 WHP.

 

cool thanks i do have v1 j~pipe and 3rd cat delete so im happy thanks for the good news..

 

hey champ did you ever get you mm delete and if so how do you like it isnt it great...

And if someone would do something like this for this forum, he would be called a liar with the real results.

 

I would still like a dyno result to see what I am purchasing.

 

it fucking pulls.

I have v3 jpipe and v3 pcd's.
60lbs lightened.

she pulls at 5k.

 

Not yet :/

I'm saving up for the turbo so I may end up building a custom exhaust with stock tips. I may get MM delete just for the heck of it.

 

mm is a waste. just save

 

if you do get turbo you gotta let me meet up with you to check it out and maybe take me for a ride!!! ill buy you lunch or something!!! save and do it!!

 

mine was free!!! so every bit worth the 30mn wait

 

you'll hate it once you put the pcd's on.
once, you upgrade parts of your exhaust, that cheapy stage 3 mod becomes extra cheapy. i get rasp on stock exhaust, it;ll sound extra ricer with the stage 3.


so if your ultimate plans is to upgrade exhaust components, dont do the stage mods.

 

^^^ ya my pcd's just came in today; and i was wondering if when i put them on if my mm delete was gonna affect the sound... do you think if its super raspy and i put the mm back on it will help and will i retain any kind of special exhaust sound besides the rasp from pcd's i do have cai; v1 jpipe & 3rd cat del...

 

you need a resonator. at least 18 inches from what I've been reading.

 

as a replacement for the oem one the one just before the mm? and any idea what brand or part #... im sure you dont mean the dynomax or magnaflow the ones for stage's 2 & 3 right...

 

You have to find them on there site. The stage 2/3 resonators are only 2.25" I believe.

Go buy an exhaust so you won't need to get a bigger resonator.

 

i dont want exhaust and plan to never buy one... i already decided to sacrific sound for power probably wouldnt even get the resonator maybe if under a $100 or if the mm back on would help maybe that... i wouldnt wanna have to deal with reinstalling my LS tips...thanks for yalls help...

and ill stop posting here because i feel were taking over this guys thread even though the topic is cat deletes...
