i had the code read and it said something like "catalytic sufficiency failed" dont remember correctly though

^ i believe using a breaker bar... this is one of the like 2 mods on my car i did NOT do myself..
Also, ask Al (stillhere153) im pretty sure there is a "honda crank" tool you can buy for a couple bucks that make it easier

definatly a failed attempt at installing these with the blower on ..i was had everything until the removal of the front...i left the front heat shield off..hope thats not a problem

Agreed. If that pulley is wobbling around due to a loose bolt, it has the potential to take out the crank. That would be a nice $7,000 mistake.

well no cuz here is the thing, I anticipated the rasp and drone so when I did my custom catback few days ago I had ordered an aero 2.5" resonator... so it just sounds real deep, no drone, no airy sound as reported by a couple of members, no vibration on the interior... just low end torque, sooo much that the wheels brake loose with vsa on
ps. on v6 p there is an accord guy who installed the precat deletes on a car with the stock exhaust, reports that it definitely sounds deep and yielded some very noticeable gains, no dyno graph tho

The other thing is you got rid of the stock heavy metal dampner and if your car was already a little sensitive to vibration, you might notice this.

Blackura.. Tisk tisk tisk, you haven't been paying attention... The precat deletes yield double that n/a, he is going to get 10hp on top of the 20-25hp n/a picks up
Type-s09.. Good luck keeping traction on the launch, I can't I keep trying, it slips loose at a 2k rpm launch in an auto

.. I am in midtown right now, as soon as I go back home I'll pm you the requested pics and tracking number... Also have to measure the outlet of the primaries for omp who requested it on the other page of this thread...
Does that mean mine are in the mail?

No one has ever shown what the gains going stock TL-S to TL-S procats. You're inferring because the 3.2 6MT got 21hp from procats, the 5AT TL-S will get 25...
...and I think that's way wrong, as the TL-S already has free flowing cats stock. I'm bettign money you don't get more than 15 HP going stock TL-S cat to deletes.

The key is not for load bearing, it's for alignment and will bear some load if the nut is accidentally not tightened enough but it's not made to do it for long.

I wish the power gains were linear like that... Guess we'll have to wait and see someone do "stock" to "deletes" pre/post dynos.
Good luck guys.

Well if I go to blackura's dyno in speedworld (baldwin, ny) it'll read that over inflated... anyway, so I called them up and their tach reader thingamajiggy was inop so they wouldnt be able to give us any tq #'s... so I went somewhere else in jamaica, ny... $75 for 11 pulls, 2 cars

obviously, this dyno shows a bit higher then the one they used, but i only use dyno's as a comparative measure tool... i pulled 273whp with everything i've got & stock tl-s cats.... so, when i put on the pre-cats, ill dyno again.... granted its going to be much warmer outside then my last pull in April, i should still have a rough idea of the gains achieved from these....
all this hype is getting me a little anxious to get over 10whp..... but only the dyno will tell!!
also, i am gonna retain the 3rd cat, so that will also impact my power gains.... ive been so busy, that these cats are just sitting in the garage waiting for install... i should have it done in under a week

Catless temporarily, the smell isn't as bad as I'd imagined, well if you are idling at a redlight and there's a crosswind windows down, it smells like I am running race gas rofl

Ps. When you gonna be in north bergen, it takes me under 4hrs to do the install now that I've done it 4+ times...

I think if you are really trying to see about power mod increases you need to stay consistent on all factors like place you dyno'd and even things like temp. You cant compare this guys numbers at one place to that guys numbers at another. Its pointless. I will hopefully be back to the SAME dyno in a few weeks when my big bore throttle body and manifold are done. I want to get back asap since it is still hot outside and I dont want anything to skew too much.

285HP/275 TQ (best #'s I've seen on a N/A TL-S, other than Racingharts juiced version) @ 3600 lbs does not equal 300HP/300 TQ @ 3500 lbs (Stock 335i)...
Keep dreaming though.

plus, all you gotta do is buy the vishnu package (ecu & exhaust) for $1900... and you'll gain almost 70whp !!!!!! thats serious power

i think your wrong....i raced 135 bmw and pulled on him jst with an intake with my tl and its auto and 3.2L... now i did alittle bit more work to my car j pipe pully and i have a few other plans too but i need to do alittle bit more work like precat deletes and full exhaust and i think i can beat a 3351 stock ....if the 335 has work there is no way i am keeping up with it with out a s/c....and jst bc the 335 is fast doesnt mean the driver knows how do drive it "am i rite or am i wrong"..... i think it depends on the driver....i think your giving the 335 to much credit....
