I am currently in the market for a 3" cat-back and I am looking for some opinions. I am looking for the cat-back that is the quietest while still being free flowing. So I defiantly need a resonator and a muffler.

Here are the options.

Does anyone have any feedback on any of the systems?

I have been told the Hahn system is pretty quite.

 

just FYI, the ZZP has a whisper resonator. not sure who makes it, but its not magnaflow (maybe a ZZP product?) I remember when the resonator was sold alone, it was a very loved item. Only 1 person has their full 3" catback though since they redid it a few months back

 

i have the hahn and its deffinately high quality. sounds great even w/ out a cat. can still hear a little rasp but only when im in part throttle around 4-5k rpms

 

CIA also has one, around $500.

 

I like the sound of whisper.

If you go to their website is says Magnaflow Resonator.

I have heard many good things about the Hahn cat-back. But I don't know if they make one for the RL. I will get a hold of Hand and see what they have to say.

Even more options?

I will add them to my first post. Their stainless version is pretty pricey.

 

I personally really liked my clear image Header / DP... i checked out their catback as well and it looked VERY nice...

 

hmm i'm looking for the same thing right now .. good luck with your results

 

Hahn will fit with modification and it sounds very good too. Fran has it. Have to make custom brackets and maybe lengthen it a bit. If money doesn't matter I'd get Hahn's...

 

what about mandrel bend systems 3" catback with res... it's 460 with the res

for aluminized

stainless

 

If price isn't a big concern for you I'd go with the Hahn. Seems like it's the best best quality of them. I haven't heard anything bad from anyone who has it.

 

i have the mandrel bends 3" system and I like it, even if it is a bit loud for my tastes. sounds ricy till it warms up but after that its not so bad. just loud lol

 

I have the cti 3" catback and i love it .Fit was better than oem.

 

yes sir i'm very happy with my hahn. everything fits, just need to add some pipe to extend out the tip some more.

 

I was just about to suggest them lol Glad I read the whole page first

 

I have not heard great things about them.

How loud is it?

That sees to be the general consensus. I have not found one complant about the Hahn system. But I am looking for a bolt up solution. I don't want to mess with the hangers or the tip.

 

Ive heard the mandrel exhaust systems is a hit or miss on fitment (nothing a little work couldnt fix) but no one has complained about the sound of it... It doesnt have resonators built it (the option is there) but you will be better off getting a resonator at a muffler shop for wayyyy cheaper.

 

The whisper resonator is made by vibrant. it sounds really good. real deep but rather quiet

 

you can have them weld one in for like 60 bux or so.. it's not bad.. and it's a 14" magnaflow

 

Not that bad,i also have the cti 3" catless dp to.

 

I have the CTI header/dp combo. I am pretty happy with it.

 

Then you will love the catback then.
