[B16 OJB]

has anybody removed the pre-cat aswel as the main cat?

I have removed that main one but was thinking about removing the pre-cat too.

I tried with different settings on the stock exhaust system, and found out that removing the secondary cat and leaving the first cat with stock exhaust is the best setting.

I tried putting on a straight through pipe with the 1st cat and decat the 2nd cat, but suffered badly on low end torque.

I will be trying with a Ktec racing catback exhaust and see how it goes.

Anyone with the 1st cat removed with a dyno map?

We have to find out the reason right?

i can only see the second cat pipe!?

 

[scandezz]

yea..ill take a pic when my car gets hoisted the next time.. but i believe the custom pipe will be useful on track as the torque after 5000 rpm improves though the low end suffer.

I believe B16 OJB meant ""Y-Pipe" for OEM manifold" they didnt mention if its decat or a highflow cat


*knock knock*
Anyone else decat the first and 2nd cat and it works fine?

[mbarnes]

search you tube for RC racing 197

 

[B16 OJB]

DIDNT SHOW MUCH?

 

[RS#SA]

I have removed both cats but i had a new branch and free flow made up for me and wow what a difference
it sounds awesome and has longer legs in the higher gears

 

[kevo66]

Pics? Vids? Dyno charts?

 

[B16 OJB]

any videos of sound or pics of manifold?

 

[RS#SA]

i will take some pics and vids
no dyno yet have not had chance to do that yet

 

[ben_r1]

It would sound epic with no cats and im sure you could spit a flame or two. However i wouldnt bother as people say, even removing the main cat has it troubles.

 

[B16 OJB]

im on with removing the pre-cat.

i have already removed main cat

 

[B16 OJB]

you have to remove the subframe to remove the exhasut manifold!
