Okay, so i just got done installing my ark catback, and zzp 2.5 dp with cat.
problem#1 the mfg cross threaded the o2 sensor behind the cat so when i went to take it off it was a bitch, got it off and the threads were so effed i couldent salvage them, found a spare o2 sensor lying around anf plugged the hole until i can get a new sensor(tmr)

problem#2 this exhaust is way tooooooo ******* loud! i can even hear myself think when im barely on the throttle. no leaks at all either. i had straight pipes no res no cat on my old car and it wasnt as loud as this. should i try buying one of those spring loaded or just generic muffler silencer and try to quiet it? if that dosent work im going to have to weld on an additional resignator.
im driving down a major road, barely accelerating and im setting off car alarms in surrounding parking lots, how embarrasing i look like a ricer. well atleast the exhaust fit perfectly and looks nice

i have the exact same problem.. 2.5 zzp header/dp combo w/cat and its f'cking stupid loud... and the part i dont understand is neutral revs its sounds amazing, but under a load it sounds ridiculous loud.

 

you are exactly right it sounds awesome under idle but when you get on it you sound like a honda

 

i would be ok if it didnt do it until you got on it, but if you dont take off at grandma speed it sounds like your taking flight... im going to see have having a resonator welded in, or have the stock one added.

 

i had zzp shorty 3 in dp with cat and 3 in mandrel bent exhaust with a magnaflow straight through muffler and one resonator and it sounded ****** GREAT

 

so you had a resonator in yours?

 

hmm. im going to try this ebay silencer reign and i'll let you know if it works before you spend all that money getting another resignator installed

 

well the problem is i dont have a resonator at all, b/c i got a 2.5 monza catback but it doesnt have a resonator... so let me know...

 

oh i have a resignator, so i can imagine how loud yours is lol

 

It's "resonator" not resignator, lol.

I knew a kid that used to say that all the time and it made him sound like a complete tard

 

woah chill out sorry i say it the way you type it i just spelled it wrong.

 

Haha, i wasn't drilling you, I was just lettin you know

 

lmao

 

just got in contact with ark directly. they are mailing me all new bolts(used ones looked like ****) new gaskets(used ones look like ****) and the silencer for the exhaust.

oh for only a 30 dollar fee lol

 

let me know how the silencer works...

 

i hope it does lol or else it off to the muffler shop or i'll try putting the stock exhaust back on with leaving the dp on and see how it sounds (i took the exhaust off in 1 piece w/ no cutting)

 

i think your gonna need a muffler shop to weld on the resinator , but i could be wrong , i welded my exhaust anyways, lmao so whoever gets my car is gonna get an airbox mod and welded exhaust from the downpipe to the catback which makes bolt on cat back impossible lol

 

ha. i took off my stock exhaust in one piece so if i ever wanted to go back. its worth the try for 30 bucks if it dosent work i will then try to swap the stock exhaust back and sell the catback and buy a gmpp one

 

How the did you get the stock catback off without cutting, i havn't tried but it looks like that would be impossible.

 

the only way ive ever heard of ppl doing it is to unbolt the rear shocks so that the axle drops
