View Full Version : CS Mounts and OBX

Anyone else running this combo?

Mind sharing just WTF you did to get that steering shaft back on?
All I'd read previously was a "little" dent in the tube had to be made.
This is going to have to be one SERIOUS dent to get the shaft back on... looks like it'll be dented nearly in half.

I read another thread in here and a guy mentioned he couldn't get the steering shaft back on even with the header completely off... which is what mine looks like right now--crazy.

I held the stock MM's up beside my CS mounts and the CS mounts look a hair shorter, but not enough to cause THIS.

Any advice?

what size OBX headers do you have?

The OE mounts give a little when installed with weight on them..the CS Mounts are the same as the OE compressed height.

They're 1 7/8"

I ground my steering shaft down some. I'm running UMI's. Still very close clearance wise.

i had to cut one of my primaries and have it welded on. They cut out a piece about the size of a quarter, bend it in a "V" and then rewelded

It should be a little dent. If it's not, either the Creative Steel mounts are causing a major problem, or you have a funky set of headers. I estimate that I had to put a broad, 1/3" dent in the side of the headers to get them to fit.

The obx headers fit tight. I'm tempted to pull em and order kooks and put my steering shaft back to normal

It's not as bad as i made it out to seem. I needed a fresh pair of eyes since I'd been working too long. I was having trouble pulling the steering shaft down to the connection, so it's shortness made it look like I had to come over more.

A buddy of mine called me after he got off work since he'd missed a call from me earlier, so we pulled the DS back off and dented that area (as described above--a broad 1/3") and it's all back together now.

Good deal! Glad it worked out.

Just thought I'd add that I really like the CS mounts. I wrapped them in the extra Lava wrap I had from the headers and then put their included aluminum heat shields and for the hell of it put the original worthless heat shields on top of those. I don't think my mounts will be melting anytime soon.

The sound from the headers is awesome. Needs a tune badly though, it's running very rich... and my very rear PS bolt was broken before I even touched it. I might have to pull a head to get it out. There is an apparent exhaust leak from that side.

I think I'm gonna save for a few years and get some Kooks. I absolutely hate frustrating header installs....but from the look of the cramped engine bay it will inherently be frustrating!

OBX is a carbon copy of Kooks. 1-7/8" header installations are frustrating on the V the first time. Once you've done it once, it's not so bad.

My kooks 1-3/4's I had on my old car went on just fine with no clearance issues at all. My first thought on this car was that OBX headers were just a PITA compared to the kooks but their fit and finish of the OBX is really quite nice. Taking the size difference into consideration between the kooks i had and the OBX i have now... I really think any 1-7/8 headers would be a tight fit on our cars. Its just more heard about with the OBX since they only offer 1-7/8.

I was told by a buddy that his buddy used OBX headers on his V and lost power with them and claimed that they are garbage. I find this highly unlikely considering the numbers my car puts down with them and everyone else i've seen on here has had good gains. Anyone else heard bad things about the power gains with OBX??

That sounds like a case of someone's butt dyno being way wrong.

My thoughts exactly. Just didn't know if anyone else has heard the same thing. I found it hard to believe.

fuzzy logic just noticed that u have kook's cats do those bolt right up to the obx?

Pretty sure they do. When I had my kooks, they came with catted connectors and I sold them on here to go catless. The buyer had obx headers so I'm pretty sure they bolt right up.

awsome cause i heard the obx 'catted' arent realy cats

OBX used to exclusively sell headers with resonators which looked like cats, but weren't. More recently they offer catted connectors with them which I can verify are actually cats. They are tiny though when compared to... any other cat I've ever seen. My CEL is on, likely because too much air is getting by. I will be getting it tuned very soon.

The Kooks 6760-FC cats are compatible with the OBX headers. They bolt right up. However, if you use these cats, beware: thely are NOT compatible (at least not initially) with the Magnaflow 16637 exhaust, which was designed to mate where the headers end.

I did my best with a Sawzall on the Magnaflow setup, but couldn't get it to fit right because of the geometry of the angled Magnaflow intake. Wound up paying a shop $150 to modify the exhaust. Now it fits great.

Even the catted connectors don't fit the stock exhaust perfectly. The collectors are actually closer to the transmission than the factory catted connections (with flanges that bolt to the cat-back). So the slip-fittings aren't on the cut pipe perfectly square. It was tricky getting them on, but about 45 minutes of finagling got them on. Clamps should take care of the imperfections of the misaligned slip-fitting.

The trick was pushing the cat-back as far back as it would go, sliding the slip fittings over the trimmed cat-back loosely, then fitting the flanges to the collectors, and finally bringing the cat back forward and snugging up the slip fittings.

First I was trying to put the slip fittings on firmly without the cat back pushed back and then trying to push the cat-back to the rear while aligning the flanges... wasn't workin.

So wait... The magnaflow catback will bolt right up to the long tubes without the extension pipes/cats?

I'm gonna say not likely.

The collectors don't end up in the same position of the stock flanges after the cats. At least with the OBX, I can't speak for others.

Obx is that I have so some cutting/welding will be needed as I thought. No big deal but I was about to be happy if they'd bolt right up lol
