Alright so before i go any further my setup right now is as follows:

Badmab shorty header
3" Cattless ZZP downpipe
3" Mandrel bent Borla exhaust

Needless to say this is super super loud and it needs to be quieted down alot. So im now asking what are my options? would getting a catted downpipe make a difference ? There is only one muffler and its right at the end, not sure what model or anything all i know is that its a Borla muffler and its pretty straight threw ( as in there isn't much being muffled. It does seem to be making more power but it sounds like a jet engine lol.

 

From what I've seen in recent threads, I don't see a reason to go higher than 2.5" for a supercharged exhaust. If I remember my correctly from my tech knowledge (I'm working off old knowledge here ) s/c's tend to like a little more restriction on the exhaust side.

 

Thanks! I just spent allllot of money on the set up so im looking for ways to silence it a tad, not replace anything to big

 

add a resonator behind the downpipe, you have a long straight length of pipe to add one in. that should help quiet it enough

 

awesome, thanks. so adding a Cat wouldn't do much?

 

I got mine custom made but all i have is the factory cat welded into my downpipe and a flowmaster muffler and it sounds a ton better than cattless and I made 228 just from the 3in exhaust

 

You have a catted downpipe and just one muffler on a 3" ?

 

Yup sure do wanna hear a clip?

 

Yea sure that would be nice!

 

The Cat + a resonator should help. Mines a bit loud still, but it's no where near no cat. LSJ's don't sound super great catless. It's a danm shame.

 

I would say that both a cat and a resonator will help. Here are two vids of my 3" setup. My exact setup is in my sig.

SK that sounds so bad ass.

 

Well I will upload some clips of mine in the morning my setup is badmab header zzp downpipe factory cat welded in and then flowmaster with a four inch tip. I got a couple short clips lol my brother is a terrible cameraman

 

Put a cat in...high flow...if its still too loud, go with zzp's whisper resonator

i have a 3" straight pipe side exit no cat no muffler....but i'm turbo'd

 

Thanks, that does sound awesome. does that have the Resonator? i no its optional right?

haha sounds good. that would be an easy fix if its not to loud still.

 

Very first start up


Slow take off then coming back

 

Thanks

It has the resonator installed along with the catted down pipe.

this thread is hella old but might have some good info in it for ya

 

Im a little over a 2 months on the setup and its got deeper

 

Would anyone recommend any of these parts? the high flow cat and or the resonator?

 

Did it not work?

 

Thanks for the Link!!

and yea they work now, they were not at first. sounds pretty good, still a lil loud tho.
I think a resonator and a cat is going to solve the problems lol

 

This will deff do it

 

Ok this is what i have found.
vibrant resonator and a ZZP cat? any options on this?

EDIT: im only not getting the ZZP Resonator because its only 2.5"

Just go generic on the resonator and a high flow cat, but without the resonator on mine I can take off slowly just drivin miss daisy style and hear the supercharger thru the exhaust it seems like ahhhhh lol
