recently startedsaving for atlp exhast. jus purchased the comptech headers this winter. Need to kno if i need anything inbetween the headers and exhaust. high flow cat??? or is it a cat delete??? dont want it to be loud. please help.

 

if you don't want it to be loud... keep stock cat and headers... haha

or get different exhaust.

 

that was helpful. not super loud. dont want to wake up neighbors. loud but not to loud is what im lookin for.

 

is there a cheaper alternative to comptech headers? maybe a different brand that would be... not crap.

 

I drove someone's TL with CT headers, high flow cats, and an ATLP exhaust. That shit was way too loud for my taste. It sounded NICE, but I think it would give you a headache after a while.

Just leave your cats alone.

 

ATLP exhaust alone = wake up neighbors.. unless you just leave the car in gear and let it crawl...
XS Headers.... if they still exist.. haha

DC Sports... Megans... there are more but fitment is questionable.

 

if you've seen my videos of the ATLP exhaust.. its just Exhaust and headers only..

 

i have comptech headers and stock cat and atlp exhaust. its very loud if u dont want loud i dont think thats the right way for u to go

i put a high flow cat on before and it made the exhaust really raspy so i took that off

if you want a quieter exhaust try tanabe my buddy has one and its alot quieter then my atlp

 

if you want even quieter.. get Apexi WSII


but might as well stay stock

 

if u want quiet just keep stock!

 

still want the crazy header and exhaust gains comptech headers + atlp=20-30hp correct?

 

will it be louder than a suby sti with cat bac or a civic si with skunk 2

 

sti with a catback is waaay different from a civic si with funkdos

 

how you gonna compare a boxer engine to a honda, lulz.

 

if you're comparing dB, wrx/sti's are up there compared to tl's.

i have stock headers and cat with atlp's... i personally don't want it any louder lol

 

yes i was comparing db. i know they sound way different but loudness wize. those are cars i hear everyday. so i wanted a rough idea of how loud in decibals it would be. not sounding the same

 

Get the comptech exhaust. It will give you a nice tone and its not too loud. Plus (if you can still find them) they have the quiet tip inserts that can be put in to tone it down for longer trips.

 

but it wont get gains like the atlp exhaust

 

atlp gives the most gain i believe about 9-10whp on there dyno.
