Im trying to decide what to do for an exhaust system. I want nice sound but nothing over the top obnoxious. I was thinking about doing just a catted down pipe and leaving the cat back as is. I wanted to see how many people have an aftermarket catted (or catless) downpipe with a stock cat back.

If you have a set up like this could you post some videos so I can get an idea on the sound?

Thanks!

 

i have the catless dp and stock exhaust and its not too over the top at all. pretty quiet most times untill you jump on it

but def louder than when my cats were on

i would def do it this way again and have no regrets from a sound standpoint at all

 

Go catless and thank me later.

 

Catless isnt an option for everyone some have to pass state inspection

 

Keep your stock downpipe




Simple as that...

 

^^^ agree keep it and you can switch them out in like 30 minutes.. catless is the way to go.

 

yep x2

 

Even more so, doing ANYTHING to a catted pipe is illegal INCLUDING replacing it with a catted pipe, unless it is the OEM one.

Period.

 

Whenever my downpipe gets here I'll make a vid

 

for u maybe =)


some dont live in a police state haha

 

I have a catless downpipe if you want to buy it...

*edit* nevermind I just saw what forum this is in...mine is for an lsj

my bad sorry

 

i have a highflow cat and dp and catback from vibrant and its pretty throaty but quiet when not on the gas...

 

im getting the CIA with cutout. ill prolly put it on with my Stock cat back for now

Highflow cat(bc im in cali)

3 in stainless. ill let you know how it sounds.

 

good input so far, thanks guys. So you guys with the catted dp's are you getting any increase in sound? Im not sure if I want to go with catless, ma is pretty strict, and they just got more strict recently.(the sticker machines now have web cams so they can tell if youre actually testing the car you say you are). I appreciate the advice, lets get some vids up too!

 

Id say get that cat then man!

 

I have the catted CIA dp with a Hahn exhaust....With the exhaust and stock down pipe there wasn't a big difference (still only boosted around 17-18psi)....little louder and that is about it. However, when I changed out the down pipe I found that there was a really nice difference. I am still boosting 20psi (it has been a week)...and the car handles much better (more responsive, smoother, louder - but not obnoxious)...keep in mind that I am still stock-tuned so it has been interesting to see the increase in boost....
