JSM DOWN PIPE INSTALL-Help Needed

I need some guidance / pointers from those of you who installed the JSM 3" down pipe. I have the pipe with the flange finger tight on the turbo and cannot get enough clearance at the point where it goes by the exhaust manifold near the fire wall. All the clearances with the firewall and frame are good but when the pipes are connected, it is almost touching the end of the exhaust manifold. I opened the holes in the flange a little with my dremel, but there is still not enough room. How in the heck am I even going to get a band clamp on it when there is no clearance. Do I need to grind a little off of the manifold? Any help or advice would be greatly appreciated. I have already spent about 5 hours on it and have gotten no where.

You can try to loosen up the 4 bolts that attache the housing to the manifold so things can move, a little bit there is a lot that far back.

I also like to use these clamps myself.

Re: JSM DOWN PIPE INSTALL-Help Needed

I have loosened all the bolts and tried moving it up , down, left, right,and still no luck. I slotted the holes a little but its still so close that its almost up against the manifold. Thats the kind of band clamp that I want to use. Do I need to open/slot the holes even more?

i think you guys are not talking about the same bolts. I believe Jeff means the 4 on the turbo mount and you are talking about the ones on the pipe. JMO

It is called a "band clamp". I have been using them on my truck for years with great results. The band itself is made of stainless steel so, it doesn't rust. The really nice thing about them is that they don't "crimp" the pipes together like a normal exhaust clamp does. Makes getting the pipes apart a piece of cake...

I have been getting the walker mega clamps, they are very similar to the pic but they don't have the spacer and nuts its all built into the band. Summit sells them and I have gotten them from my local bumper to bumper also.

Just an fyi :D

That is the style of clamp I used and It tightend down great they are a little hard to get into place.

I got a 3in band clamp from NAPA
 
Re: JSM DOWN PIPE INSTALL-Help Needed

I will loosen the manifold bolts and give it a try tonight when I get home. The whole time I was trying to do it by moving the pipe, I did not even think of loosening the manifold bolts. I will let you guys know how I made out.

Re: JSM DOWN PIPE INSTALL-Help Needed

The turbo exhaust housing to exhaust manifold bolts being loose can make things in the back move more than you think due to length of the pipe.

The 3" is tight for sure, just no way around that. If you get me a picture I might be able to give you a few more suggestions.

I have ATR headers with the RPM DP & I had to tap the WG tube in because it was hitting the Header tube. Just minor adjustments sometimes helps A ton.
 
Re: JSM DOWN PIPE INSTALL-Help Needed

Last night I loosened the nuts that hold the turbo to manifold. I had to disconnect the oil drain line so I could get in there with a wrench. I got enough movement to clear the down pipe and install the band clamp. I ordered the band clamps last night from Summit. They will be in in a couple of days. I got one lap joint clamp for connecting the two pipes and one butt joint clamp to connect the pipe to my cat. I will probabally have about and 1/8" clearance between the pipe and the exhaust manifold once the clamp is installed.

I cut a 1 1/2 inch piece off of a allen wrench with a dremel and stuck it in a 10mm socket and used a 1/4 wobble joint and extension to tighten the down pipe bolt on the back side. From the top it was easy access.

Is this gonna be enough clearance? I don't want any issues with the pipe moving and hitting the manifold and causing false knock. Would it be ok to remove the turbo and drilling the holes in the exhaust flange to the next drill bit size and getting some extra clearance? I Have lots of room between the down pipe and frame and the firewall. I'm about 1 inch from the frame and about 1/2 inch from the firewall.

I could take some pics tonight and email them to someone if they would like to post them for me
