Suggestions on aftermarket catted section 1 or weld on cats ?

[avusblue]

So I have aftermarket headers, and euro catted section becoming hard to find. I don't really want to spend 2k+ on supersprints, but I'm tired of the smell lol. Thought about just welding 200 cel cats on my section 1, any suggestion on what brand or where to buy one? I saw some company in Germany selling catted section 1 for around 600, not sure if it's any good?

I did a review of it in my steelgrey journal. Another member I know then bought a set and was happy as well.

Yep, works great!

I used welded in 200 cell magnaflows in my section one. It definitely cut down the smell- but from prior feedback I’ve received here and other reading around, I understand the money saved also leaves performance and odorlessness on the table. I’ve since ordered fabspeed sec1 with HJS cats, and after 8 weeks lead time they’ve finally shipped this week. Still, on a budget ($600 ($500 for cats, $100 for labor)) it definitely helped.

Which magnaflows cat did you use? what size works with our section 1?

the fabspeed sec1 w/ HJS looks really nice, but it's 2200

I have the HJS catted fabspeed and it's a quality piece for sure but not sure I'd pay that much for it. I lucked in to a deal on the old forum a few years ago.

These are the cats on my car currently.

Edit: Looks like I over estimated a little at $500 for the cats, was going from memory. I sent you a PM regarding my existing set up, if you’re interested in buying it once I install the new section one.

Just weld in

Did you weld in bungs for the secondary 02s or just code them out?

It's been a couple of months since this post, any noticeable difference between your Fabspeed/HJS setup vs. your old section 1 with Magnaflows? I've been running an OEM section 1 w/weld-in Magnaflow 200 cells, but I'm looking for an excuse to switch to a SS v1 header and catted section 1 setup sometime.

FWIW, the HJS cats (Supersrint v1 pipes) kill all the smell, reduced drone/rasp, and don't rob any power to my butt dyno. The cheaper cats I've had (magnaflow 200 and the one I mentioned at the beginning of this thread) don't hold a candle to HJS.

There is an appreciable difference in smell, probably for two reasons; the higher quality cats but also: when I pulled the welded section one down to swap with the fabspeed section, I noticed the tech who welded them in place did not do a good job, leaving a 2” un welded gaps at the top of each joint. They were cut in and welded with the OEM section one in place, which I think is pretty standard.

Anyway- sound, performance and smell are all great with the fab speed HJS and would def buy again!

bring this old thread back up. reached out to a few members regarding their experience with fabspeed. results have been 50/50. i'm actually considering just buying the cats and getting them welded into my euro section 1 (clogged cats). from doing some research i dug up an M5 board post from HJS USA and they reference part no. 90 95 0092. specifically, they state: "Our model 9095 0092 HJS Hi-Flow Universal Catalyst can handle an engine up to 2.6 Liters and 240 HP, while two can handle an engine up to 5.2 Liters and 480HP. "

has anyone looked at what specific HJS cat would be a good replacement for our cars? for those with the fabspeed, care to share what it says the part no is on the HJS cat? shipped from germany i'm looking at about $1050 plus welding. yes, some can say it's not worth it, but considering 1)fabspeed would take a few months and 2) savings is savings.

appreciate any feedback.

update on this thread. i bit the bullet and ordered the HJS 200 Cell Cats. they arrived today. dropping them along with both my euro section 1 and my US section 1 so the guy can decide which is the easier/better unit to cut/weld.
while this isn't the same as a supersprint catted section 1, it hopefully has a better fitment than some stories i've heard regarding the fabspeed unit.
