Features & Product Details

If you're looking for a means of really securing your exhaust system, then you will be pleased with the COBB Tuning 15MM Blue Exhaust Hangers. Unlike the factory hangers that are made from soft rubber that becomes weak over time, the COBB units are super tough and are made from high-grade polyurethane materials that you almost have to man handle when installing, which isn't a bad thing because you'll recognize how tough these are. 

This is a great option for those of you with an exhaust system that is either heavy or if you need a hanger that will keep your exhaust system in place especially if it's close to the bumper. 

These are standard length and are sold separately. 

Note: 02-07 WRX exhaust utilizes 4 hangers
Forester XT exhaust utilizes 3 hangers
04-07 STI exhaust utilizes 4 hangers

This is a great option to replace the original hanger, especially if you're replacing your OEM exhaust with Performance exhaust. No worrying that exhaust system will be swaying or rattling, very solid.. just make sure to use spray lube to help withe the install. I highly recommend!

Really impressed, the only real thing is at least on the Perrin exhaust these were brutal to get on. All the WD40 and some real work and they finally went on but just. Exhaust doesn't wiggle at all now, really happy with it.

Replaced only 2, did the job, no more speaking. Extremely stiff compared to the old softened ones they replaced!

I meant to order 3 but only bought one. It fixed my rattle issue though. I switched out the rear right which wasn't too bad of an install. The factory one came of easy putting the new one back on sucked a little bit but it's on. My advice put it on the muffler first and then slide it over. WD-40 is your friend.

Too short 5 years ago
3out of 5stars

I figured I would try these since the last Kartboy hangers I bought failed within a year. The Cobb hangers seemed to be a little better construction & the color matched my WRB WRX nicely but they ended up being too short to use. (partially my fault for not seeing the dimensions though) I am wondering why Cobb doesn't offer a long version of this product?

  • Q: Fujitsubo  EvenTheScore4 years ago

    Will this allow enough extra length for the install of a fujitsubo power getter? Its known to be quite a cumbersome exhaust.
    • 0 of 0 people found the following answer helpful

      A:  These hangers will be OEM size and if you wish to have the exhaust sitting lower than factory, we recommend Kartboy's Long Exhaust Hangers which will drop the exhaust about 1in lower than factory.

  • Q: question  jdmcglynn94463926 years ago

    So if these are standard size hangers and theyre 15mm and the only ones are 12mm which is shorter than how am i supposed to get longer hangers..?
    • 0 of 0 people found the following answer helpful

      A:  12mm and 15mm refer to the diameter of the hole and not the length of the hanger. Most 1993-2007 Subarus use 15mm and 2008-2013 use 12mm.

  • Q: cobb specific  silver bullet6 years ago

    I just installed my cobb catback on my 04 wrx. I noticed that the mounting hooks on the cobb muffler were a lot smaller than the stock muffler and now the stock hangers are really loose? do these hangers have one smaller hole for the cobb muffler with a larger hole on the other side for the car hanger side?
    • 0 of 0 people found the following answer helpful

      A:  The hangers are the same size as stock, what happens is over time the stock hangers stretch out and make the holes loose. So if your hangers are stretched getting these longer ones will help out.
