will my exhaust be loud with plm toda rep 2.5inch mandrel bend cat back straight pipe with a hot dog with 2.5inch apexi n1 muffler? if I put a hi flow cat will make it quieter? is $350 for a hi flow cat reasonable price I have been quoted $900 to get the lot done just wondering if the hi flow cat makes a big difference worth getting ?also do I need a flex pipe?

Hi hi,

Is the Apexi N1 an Evo version [ie JASMA Approved, Newer] or is it just N1 [ie Non-JASMA Approved, Older] because the Apexi N1 Evo is a cannon while the N1 iirc is just a pipe ie no muffler therefore very loud...

Sound wise, Hi-Flow CAT will be a little more silent than just a straight pipe though a resonator will help with the sound reduction more.

However a Hi-Flow CAT will save you from a $10k EPA fine...

Flex Pipe needed only when your exhaust design moves at certain pivot points otherwise not needed.

its a apexi n1 evoversion with muffler any got 1 does it sound good ?

decided on hi flow cat magnaflow 200/100 cell which one would be better?

my exhaust shop tells me plm toda style headers are shit and not worth much more then the Chinese versions on ebay after a having a quick look im abit disappointed.

Apexi N1 Evo sounds beautiful, not as crazy as the N1 but beautiful...

Here is 2 clips to give you an idea:

Cell count refers to the internal matrices construction, 100 Cell flows slightly better [Higher CFM] but some say its louder and smellier. I went with a 200 Cell because personally don't believe there is that much difference and it hasn't been smelly :p

300 for a hiflow cat is expensive, you can supply one yourself for them to fit, should only cost 130-150 this is the magnaflow brand too which are good :)

Wow! I knew Metal CAT is quite a bit more expensive than Mangaflow, but $500 o.O Though saying that the AUDM spec Metal CATs have serial number for ADR Compliance.
