need new cat what to get

[DrMcDave]

alright i discovered why my car is so loud-there is a hole in the cat.

what should i get-straight pipes are out, its too fucking loud right now as is.

should i get a high flow cat? if so where from?

just need a little help. its cool for now cause it sounds like a dtm car but i can't stand it for any type of distance, the hole coupled with my triflo is so loud is ridiculous.

DEC is an option

I've heard that stock is the best option, but if you don't want to spend the $3.4 Billion for OEM, that DEC is the next best option. Can't verify this from experience though as I'm still running the original stock cat. I'm pretty sure that BMA Autoparts sells the DEC. This place does to, but I've never done business with them:

BMA will price match (if they're not already lower).

This website seems to recommend the DEC as well:

does replacing the cat with an appropriate pipe or pipes significantly increase noise?

$3.4 Billion

Naw it like $800 bucksfrom the dealer if I remember right...

If you call up your local exhaust repair shop they will hook you up with a car for far less...I usually try to find one of those place on the bad side of town ...

Yes

Probably depends a lot on what type of muffler you have.

[E30godz]

ill sell you mine! it works great.

[LikeCDoos]

anyone ever run catless with a stock muffler?

[bmwannabe]

i would run without a cat, seeing as how heavy those motherfuckers get.
free flow+reduced weight+sweet sound = triple mods for the price of one :twisted:
