I am in the market for a Hahn Catted DP. I wasnt shoppin in the aftermarket world last year during black friday/cyber monday, but I have worked enough retail to know the deals are the best all year. Should I get the Hahn DP now or should I wait until that Friday? Do our supporting vendors have some amazing deals on the Hahn products on Black Friday?

I know I can't get the price matched if I buy now, I am just looking for the best deal and not used. Which means, I may have to wait til that Friday.

Thanks

 

these vendors arent like best buy, but i guess theres a chance... haha

 

Don't take this the wrong way cause It's a real question .... I'm not trying to start an arguement or be a fan boy...... but.....

What makes the Hahn metal spun catted DP..... so much better than ZZP's metal spun catted DP...... that it's worth spending a 100 buck more on it? I'm curious to know if it performs better or not.

 

I just got the Hahn Catted DP and installed today. This is a high quality piece...the flex section has braided steel both on the inside and outside. Flanges look very substantial and I would guess that they are THICKER than some others. Fit was perfect. Sound is very quiet until you hammer it, and even then it's not real loud. Spool up quicker now. I'm going to run a *ricer* 60-100 soon and report any improvements.
I did get a deal from Turbo Tech Racing. So contact them. I don't think you're gonna get a *screaming deal* on this pipe....Hahn doesn't cut you much slack and you won't find another vendor to beat Turbo Tech's price.

 

I have read more than ONE account where the ZZP DP fell a little *short* and the cat back had to be pulled forward. Hey..ZZP is a very good company and I'm sure their catted DP is fine. I got the Hahn because it's the *GOLD STANDARD* for this pipe. No one has EVER had a problem with it and CELS have NEVER been reported with this pipe.
I can't comment on the CAT offered by ZZP. The Hahn is VERY HIGH quality. I looked inside to inspect it. I believe they are made by Random Technologies and are Stainless Steel.

 

I believe you hae ZZP confused with OTT on your first comment. I have not heard of this happening with the ZZP DP, but I know there was a couple threads about OTTs being too short.

ZZP uses Magnaflow spun cats. We flow tested RT cats a few years ago, and they were terrible. I read that they improved them, so that may be irrelevant.

 

Matt, I wish I knew about your modular DP earlier. What a great option for someone like me. I can't stand catless for daily driving, but catless would be nice when I head to road courses.

 

To start this off I am catless

But you are the first person I have hurd that the ZZP DP is short, and the cat back had to be pulled forward, but it is true for me at lest, but I am catless. Now that I think about it I ALWAYS have to pull it forward an inch to get the bolts on. But it is no big deal, if that is to hard for you then you should not be changeing parts on your new car anyways lol.

Now besides that the DP is GREAT I picked up some good numbers off it the welds where some of the best I have seen. the felx was A+

ZZP is the way to go they are the cheapest and have great stuff!!

 

I know about OTTP problem, but I read a post or two saying ZZP was a bit short.
I now see someone on this thread has verified that (cattless). No biggie.
As far as CAT...I can't verify it's a Random Tech on the Hahn, but I'm pretty sure. This Hahn seems to be very close to the CIA Pipe..another top notch catted DP. The Cat on that one looks like the Hahn, but located lower on the pipe. I think having the cat located CLOSE to the Turbo (Flex Pipe) lites it up more efficiently for emissions testing.

 

Just noticed your SIG reference to a Porsche spewing coolant all over your car at 100 MPH. Be thankful it wasn't oil being laid down. I had that happen at Sears Point and wound up in the weeds exiting a turn. The Porsche in front of my car let go and laid down oil on the track..very scarry experience indeed.

 

zzp ftw!

 

not to start anything hahn makes some great products but to me their stuff is way over priced i can get the same quality parts from other numerous companies on here for a lot less money

 

Apples and apples..ZZP with SPUN METAL CAT (same as Hahn) is $310. Yes, *cheaper* than Hahn (which currently lists at $100 more with some vendors)..but certainly not *the cheapest* by far. BTW, Hahn has never thrown a code.....never.. Is that *factoid* worth the extra $100? You decide. Just to reiterate..I'm NOT bashing ZZP. They are highly regarded here for a good reason.

 

Hahn is recognized by GM. Just saying. I plan to go wih ZZP though for the price.

 

Let's revisit this thread again! We're talking CATTED here.
Two guys regretted not having bought the Hahn first...not mentioning any names

that don't mean anything really, people get recognized by Shelby all the time just for making a pretty replica of his cars, but it's publicity that's probably why they charge so much

if they are so good, they should try to make a contract with GM and sell their **** at GM dealers on their performance/accessories department, so I could keep my factory warranty, that would be the only way I'd spend that much for some piping

 

Here we go again

 

I've had a turbo miata punch a rod through the block while we were slowing down off a main straight. I was so close thatitmostly went on my car rather than under, kinda like this damn GT3 that popped the coolant hose. There was the time when I punched a massive hole through my block coming off a NASCAR oval to an infield...

Lowes motor speedway,or whatever it's called now

 

Well, IMO you should tune for a downpipe or your not getting your moneys worth out of it. So disabling a CEL wouldn't be an issue. If the OP doesn't intend to tune I'd get the Hahn.

I've been thinking this for months!!!!

 

I got my ZZP Catless for like 149 or something last black friday. WELL WORTH THE WAIT!

 

Ahhh ..... I forgot about that P013E code . I had it pop a few times but it went away and I didn't see it again for a good 6 months. Then I was trifecta tuned so it was turned off.

I can see if someone isn't going to tune their car , or stick with GMS1, superchips ..... or some other canned tune ..... maybe then it would be worth giving hahn the extra cash .

When i contacted ZZP about the code they were more than willing to rectify the situation ..... but it fixed itself . I'm wondering if people are still seeing this code with ZZp's DP ..... I'm guessing they tweaked the 2nd o2 bung to fix the problem in later runs cause you don't see too many people complain about it any more.

The other reason I chose ZZP was because they are putting money back into the cobalt platform in R&D of new parts and bring more options to market. Hahn has seemed to taken a step back from developing anything new for our cars. Maybe I'm misinformed but I haven't seen anything new from Hahn in quite some time.

 

I have a 3" hahn dp, and it has been on the car for a while now. I had to replace the flex pipe due to it breaking and leaking, got a new pacesetter flexpipe from summit racing and had it welded in there. that was the only problem though.

 

Really? Damn...did you race it? Do you have a special suspension on? I would have gone back to Hahn, since they are supposed to stand behind their products. Their flex pipes are supposed to be BETTER than stock.

OK..you don't have the TC..right? What I said above still stands, but that wasn't the TC pipe and is made differently. Still no excuse though.

Non Turbo pipes look like this..no braided flex section:

 

no mine isn't a tc model and i didn;t go back to hahn because i didn;t think they would do anything for me for a 2 year old or more dp. I just bought a new section from summit and called it a day, works fine.
