Rpm problem with operate cat

[chenwee]

Hi to all Bro and sis,

Just want to check if operate first CAT will make the REV cut earlier??

Before operate cat can REV up to 6400rpm....

But after operate first cat can only go to 6100rpm then car start to jerk..... ( REV CUT )

Any feedback well appreciate...

hey man, i don't mean any disrespect, but i don't understand what you have said. i wouldn't know how to answer your question. seems like your saying that, when you take out the first cat, u get rev cut earlier? i wouldn't have a clue man, sorry, ahahah maybe others are more techy.

No exhaust modification would do that unless you had a very blocked exhaust.
