Hello Zach

Its loud as hell if you have an aftermarket catback, if you have a stock catback its not bad.
Heres mine with a magnaflow 2.5. I dont think it sounds like ass as someone else said

^Nice!

Others have added a spiralflow muffler after deleting the cat to get rid of the raspy sound. I just got a downpipe with a vibrant cat, it threw the P0420 right afterwards as it would with no cat. Disabling the MIL leaves the code to be thrown, but you wont get a CEL from it. You can also disable your COT with a hi-flo cat.

I got rid of that magnafart exhaust and got a hahn 3inch. SEX. and no raspy at any rpm

Revival of dead threads, lol.


I still haven't done it yet... but I'm gonna next month. Thanks for all the advice and vids, peeps

that plug just plugs the bung so more exhaust doesnt escape. only way to not toss a CEL is to delete the sensor via tunning.

id recommend not going catless on a LSJ. sounds like shit

agree'd, i would get a 3inch downpipe with highflow cats and a nice 3inch exhaust if u don't already. With tuning you can gain a little extra punch and still retain a fairly quiet exhaust that sounds mean as hell.

u won't like it, it doesn't sound right on the LSJ and me thinks u will regret it, maybe not at first, but eventually........

 

[07MetallicSC]

I have it setup like this and wouldnt go any other way.... except emissions time

Well, if it sounds like ass, I'll just have to get the hubz to get me a high flow cat next year for Valentine's

dun do it, get the GMPP touring catback, this is my buddies LSJ stage 2 with the GMPP touring catback and an Injen intake, it's plenty loud when he stands on it. Make the hubz get u that exhaust AND a DP with highflow cat

Either way going catless or with a hi-flow, you are going to get the P0420 code and it will set off the CEL. IF your going for just plain power you wouldn't even have a muffler it would be straight piping from the header back.
A 3" exhaust isn't really necessary until your making good into 300whp. 3" DP to a 2.5" exhaust will help up until then. Getting a good header will deepen the exhaust tone no matter what catback you use.

and cams!!!!! yay for cams

But I ain't getting a DP & exhaust AND a stage 2 kit for Christmas... I set us a budget of <$600 each. Flexpipe for a cat delete is just a few bucks, anyway, lmao.

And the cat delete is just simply because I hate emission controls... AL doesn't have any, so I don't want it on any of my cars, haha. & if I get the stage 2 for Christmas, I'll have the guys make it to where the code won't be thrown (they ask if you have a cat or not). Unless I've been misinformed...

Get the stage kit (more power gain than any exhaust component by itself) if its an aftermarket deal then either Tim at ZZP or Josh at OTT, they can just set the P0420 to not set off the CEL. If you have a stock cat it wont hurt it unless they turn off COT too. If they do that then you will FUBAR the OEM Cat.

****, this shit is too confusing...

from experience:
removing the cat will throw a p0420 code reading a rich mixture on o2 sensor bank 2. this is normal with no cat. you will either need an o2 fouler or get hptuned to "delete" the code. cel is gone and you will pass inspection.

I have a gutted cat and it sounds awesome. with stock exhaust it sounds even better. big power gains too.

clear image automotive + 3" catless downpipe + stock 2.0 exhaust = sounds just like stock but better airflow. only sometimes when it's cold around 3-4k rpm's it sounds a tad bit raspy but other than that it sounds just like stock daily driving and jumping on it. i can post up video's for you within this week if you'd like. just pm me and remind me.

the real problem with any type of raspy you hear when the car is warming up or certain rpm's would be the stock muffler. the baffels can't take that much pressure and then it's over it's limit and will create raspy'ness.

if you replace the stock muffler with a turbo muffler it will dispear and hopefully still not sound loud. i will be add'ing a turbo muffler to my car eventually but in the mean time just pm me like i said and i'll post up vid's at idle and everything for you of my car and WOT so you know what CIA header+3" catless dp + stock exhaust sounds like.

haha yeah. aggree'd. but if you have hp tuners you can just shut the code off.
