  1. Engine & Performance
    To remind the clueless… I think today, I'm going with Engine-ish Pt 2. Going with some non-CSL stuff for a bit. First up we got ARH Headers with cats. Cats are upgraded to GESi instead of the normal cats that you can get with them. The headers were also ceramic coated by Swaintech. Brand...

    I'm selling a brand new, never used stepped section 1 w/cats. These use the better HJS cats. These are made to be used with the Supersprint V1 headers. I only opened them to take the pictures. Asking $2000 picked up OBO. Will ship at buyer's expense. I'm also selling the headers (here), so if...

    I'm trying to get some aftermarket cats as the ones I have are bad. I have some catless headers on the way so all I need to Euro-spec the car is some cats that will pass a sniffer test. Only thing is, I can't seem to find any place that tells me what size cats I need. From what I've read, 200...

    Went to mechanic to help diagnose a rattling noise which happened in a range of RPM's in each gear. He said something with the cats is most likely wrong, and can just replace them as long as I get cats. My question is how will aftermarket cats fit? Is it worth going high flow cats? Then i also...

    Selling my Evosport Section 1. Specs are as follows: 2.5" Metallic High-Flow Catalytic Converters, 4" OD - 9.97" Overall Length, 200 CPI Bolts up with no problem. This will not help you pass smog in CA (although it may get you closer) with catless headers, however it does help a lot with the...

    Alright so I drive a bmw e46 325i. My main question is I have a res delete and a muffler delete as well as duel glasspacks. My car is absolutely quiet. From the videos I see about a simple muffler delete my car should be a lot louder it sounds stock and I have no idea why. I have no codes about...

    Hello: It has been awhile since I have been on this forum. I stopped driving my 2006 E46 M3 back in 2010, and have returned the M3 to its stock form. These have been sitting in my basement for 2 years now, so I thought I would sell them to get new parts for my new car :D Random Technology...

    Hi Guys, I have the original catalysts / headers from my 01' M3 for sale. These units came off the car when it got headers at 52K miles. Since then they have been sealed in a plastic bag in my shed. That said they are in great shape with no rattles etc. Here is a picture of them as well as a...

    I bought these a few months ago for my E46 M3 and ended up selling the car before i installed them. You can pull up the web site and get more info about these than what i can give you. I know that the quality is great and the condition is as new. The pipes have no dents or bends that should not...
  13. General E46 Forum
    I'm just posting this because I am wondering if anyone has ever heard of or considered this unconventional idea. It's cutting out the stock cats and replacing them with piping, while splicing in high flow cats in the midsection. What is the point? To possibly maintain the sound quality of my car...
