o2 sensor bungs do these slp cats have the o2 bung on the cat itself, like the pypes brand and the stock ones do ??? thank you john ferguson

papajohn Year: 2005 Model: GT

  • They do not have the bung. At least the ones i bought a year ago didn't have them. It's pretty cheap to have a shop do it if you take them in before installing them on the car. I paid like $15 for the shop to drill and weld them in. Normally I would have done it myself but I was having welder issues.

will these work with a Bassani o/r x-pipe?

mikep02 Year: 2002 Model: GT

  • They will fit but are a little shorter then the flow tubes so you'll have to add a few inches of adapter pipe to either end.

will these fit i want to know if they fit a 2001 v6 3.8 mustang

carlos0422 Year: 2001 Model: V6

  • These will fit in fine. I believe they are the same length so you should be able to cut out the old and slip these right in. Not sure if you're aware but, your car has two resonators right off of the exhaust manifolds. These then dump into the converters and out from there. The resonators are offset a bit so these will not be a direct fit at that location.

    SLP high flows

    Overall great product with great customer support. AM price matched it for me and everything. I ended up writing an install guide for the cats in hopes to make the installation for others a bit easier. Only reason why I gave it 4 stars is because no installation hardware came with the kit. You either need to have them welded in or you need to purchase 4 exhaust clamps. (I bought 4 for $8)

    great cats

    I am extremely happy with these high flow cats. I was concerned will losing clearance under my 2008 Mustang, but the size of these cats matched the stock cats. This allowed them to be installed right where they are from the factory. Even though they are not large enough to place the O2 sensors, they can still be mounted just behind them on the pipe. Now I have that high performance, that great sound, and maintain my states requirements, exactly what I was looking for.

    SLP Cats

    I added them into my bbk o/r x pipe (long tube headers, Flowmaster 40s) They sound great. Here is the problem My stang has the lowering springs. The drivers side cat has to sit about a inch and a half lower for the tranny linkage than the passenger side This puts them less than 1 1/2 inches off the road. and have scraped them on the road a couple times now. I don't even dare go over a speed bump. I really wish i could keep them they do sound great and I'm not setting off car alarms in the parking lots anymore I am going with the MagnaFlow HiFlow Cats they are a lot smaller in diameter

    SLP High flow Cats

    I love these cats, they go great with my slp lm1 setup, my exhaust is still as loud as I want, and they fit great too. Would recommend these to anyone who needs Catalytic converters.

    Great Product

    Easy to install. I had the X-pipe off the car, but then completed the install laying on the ground with the car on jack stands. Still pretty easy considering. Came with detailed instructions. About a 1/2" better clearance than the ones I had on previously (don't know the manufacturer) because these have a flat spot on the bottom. I still took a hit on a speed bump causing a dent, and it held up. No funny sounds indicating it cracked inside. My old one cracked and sounded horrible.
