I would defo top the M2 leader board then

 

Cheers Rusty. Tha is another area that I am lacking torque!! On the leader board all the people above me are on 17% pulley but as I wana stay with 15% need to find more torque on another part currently @200.6lbs ft

 

have NO idea

it's built better than every other header out there except my race header so who knows

the fabricator who works for me has 40yrs of experience building headers and we used some of our technology from the race header into a shortened less expensive header but you still get"

1 5/8" primaries that match our Big Valve head (no other header matches our ports right out of the box)
304 stainless mandrel bent tubing
custom built collector with similar technology as the race header
high flow cat

 

Santa's shopping cart

 

Think I seen my name on one of them

When is the first one coming to the UK so 1320 can do back to back tests against the Janspeed?

In one of my earlier posts Jan I asked if I got a W2A could my redline be upped to 8k as I am on 15%?

 

yes no problem

We are not sure if the #2 pipe will hit on your steering column since you guys drive on the wrong side of the road

the car will need to be retuned to match the header

we really don't build stuff as bolt ons, we build systems

 

I do have sound clips. Give me a little bit to post them up and I'll link them.

 

Do I get the tune a bit less than the first price since its a tweak?

Well you could send a header over for me to test

We are in the minority with driving on the left side of the road so I can't really argue there but your wrong

 

I'm not going to charge you for the tune this time... it's on me

 

Video Clips! Sorry for the bad quality. I didn't have any way to mount the camera and driving while holding a camera is somewhat difficult. I'm getting a camera mount in a few days, so I'll shoot some more videos. Also, my car is VERY bumpy (Coilovers set pretty stiff on low profile extreme performance Summer tires), so all the rattles and bumps sort of add to the audio track.

I'll try to get a few drive by shots at some point. FWIW, point and shoot digital camera's don't do this exhaust justice.

2nd Gear Pull, 4500-7200 RPM's. THIS is why you don't need an intercooler for street driving! If youtube's quality wasn't so bad you could see that the IAT's peak at 96 for about 5 seconds, then drop to 91, then 85, all within about 15 seconds of redlining (While still holding the car at about 6000 RPM's).



Driveway Revving, the last rev was up to about 6000 RPM's



Dyno Pull


4th Gear 3000-5500 RPM pull, 35-60 MPH


Cruising in 5th, 30-40 MPH, then slow down to about 10.

 

Price jan?come on.im searcing for top header for my GP....Give us a price....

 

Thats great, I will try and make it a reasonable time then this time

 

It doesn't sound that loud to be honest I'd say my JCW and Janspeed with Jans head was as loud (don't know why my JCW was sooooo loud )

 

It's louder than the video makes it seem .

At 4000 RPM's or so (Cruising at 80 mph) if you're going uphill, loading the engine, you have to talk pretty loud to be heard over the exhaust. It's a race header, if all you do is drive on the street it's overkill.

Posted another video. Youtube is taking forever for these last few.

 

All videos posted...

 

cheers Rusty for the vids, don't sound to bad when free reving on the drive either.

Race header and Jans catback

Or

Jans other header with aftermarket catback

too hard to make a choice

 

His new catback is a bit different than mine. I have the V1.0 which is a modified Magnaflow system. His new one is a custom built exhaust. Sounds a bit deeper.

The full RMW exhaust is a system, the header + other random exhausts is a mish mash of parts. I'd go with the full system.

 

Jan'
Is there difference between the silent and race header in the sound that much ?

 

Based on the price of materials that I was given when picking up the stainless steel. Every part we use is stainless, no skimping on flanges etc and the cat's went up another 15% across the board + a surcharge they are asking for we are going to have to come in at $850 which is still a great buy for what you are getting. All of our steel comes from the good ol USA but it's bad for the wallet . We are working hard to keep American's working .... Maybe the Greecian's will help too

For those that have sent deposits I will be honoring a $799+ shipping price so for those that sent money.... congrats you saved $51

 

I don't know, not sure of anyone who has created a "silent" exhaust yet

Mine are far from silent, but on wide open throttle there isn't one that sounds that good

 

"2b) options for test pipe? (for track use only of course) I know people won't believe this but our dyno testing has shown a loss of torque without the cat
there is a happy medium for producing big torque and we have found it with our exhaust/cam/head systems. We have not seen one car break 200ft lbs of torque anywhere else

thanks"

Funny you mention that, I have said this for years after learning this from Gale Banks in the late 80's early 90's. In testing he often found that a high flow cat would cause no more than half a pound of back pressure at certain points in the exhaust stream but that the cat kept the exhaust gases hotter and therefore the gas velocity was greater. The cars (twin turbo) would actually loose hp with out the cat when a straight pipe was used.

 

thanks for posting this..... goes to show we are seeing what Legendary people like Gale did

 

I'm going to try to do some videos later of 30-70 runs, and maybe 5-60. 0-60 is hard to do because there's so much wheel spin, and I don't wanna light up half a city block in my neighborhood, too many police.

 

don't bother with teh 5-60..... you won't be moving

 

I actually get decent traction with these tires! They spin like crazy, but they still hook decently.

5-65 or so (Overshot 60... )



30-70 (2nd gear then 3rd)


My NavAlert read 69 mph GPS verified in 2nd, but it's close enough. The 3rd gear pull was to 71-72 before I let off.

My stopwatch shows just under 4 seconds for the 2nd gear 30-70 pull. 3.9 seconds or so... . I don't have the equipment to properly measure it, and my reaction time probably accounts for .1-.3 seconds, so suffice to say, it's pulling 30-70's in the low 4 second range .

I measured 0-60 (I did try it, although I realized when I stopped for gas that it didn't get recorded, instead it took a picture ) at just over 5 seconds. If I could put the power down in 1st instead of spinning tires I could probably break 5 seconds.
