I have a bad mab header and zzp 3in downpipe on their way to my house right now, but I am curious as to what exhaust other than zzp's is a true 3in with a 3in flange??? Any other brands or will I have to go custom? Thanks for the feed back..

 

I would just go custom if i was you.

 

mandrel exhaust google it

 

CTI makes a 304 stainless 3" exhaust.

cobalt ss exhaust

I have that exhaust with an 18" magnaflow resonator + stainlessworks.net chambered turbo muffler. Sounds soooo good at idle and cruise, and gets nice and mean at WOT.

 

So the CTI exhaust is 450 plus 175 if I want 304 stainless steel?

 

Yup thats what the site says. Totals to about $25 less than ZZP's with 3" flange, resonator, and muffler.

 

ZZP is actually 499 with 3in flange, resonator, and muffler. Thats cheaper than 450 plus 175.

 

Oh I must have misread then. I understood 499 PLUS the options. Sounds like a deal then!

 

I was also wondering is it illegal to run a catless downpipe if your county doesn't test emissions?

 

You would have to take that up with ur town. Some are strict and have noise rules but some don't. I don't have emissions testing in my town either so I run cat-less and haven't had a problem

 

Oh ok and what do you do with the sensor thing?

 

You can remove it and disable the DTC with HPTuners so that it doesnt throw a code.

I'm running GMS3, and it has the rear 02 disabled by default. To my surprise the rear 02 readiness check always says "passed" lol. Passed emissions two years with it like that now.

 

Thats awesome! Yea OP you just have whoever is tuning your car turn it off. I still have the 02 sensor in it even tho it is turned off

 

Im talking about the wires. Do you just leave them hanging? lol jk But what do you do with them?

 

worst fking quality ever not surprised you suggested it though

 

just zip tie the connector coming from the wiring harness somewhere close lol

 

Yea just zip tie them up there, they will be okay lol

 

Sounds good, but I hope I can run catless because if not Im going to be so pissed lol and I will have to return it. But yall dont think I will have a problem do you if I go with the ZZP 3in exhaust with the muffler and resonator?

 

catless will sound like crap

 

It will be loud though. You may regret it. That setup will notify everyone in a 2 block radius when you change gears or try to pass someone on the highway. lol
