Complete True Dual Exhaust System (Partially Oval Tubing)

Complete 3" true dual exhaust w/ coated Hooker long tube headers
-1/2 round tube and 1/2 oval tube (Round tube from collector to H-pipe, oval from H-pipe to mufflers to provide adequate ground clearance)
-Oval tubes and mufflers are "SpinTech" brand (Mufflers are only 3" thick)
-Made to fit around Spohn aftermarket torque arm and crossmember
-Hooker 2210 long tube headers have 1 3/4" primaries w/ 3" collectors and have welded bung on driver's side for oxygen sensor
-Pipes dump in front of rear axle, dumps are slanted towards eachother to deflect sound

The complete system has been used for a year and half. I have well over $1350 into this system.

I'm looking for $900 for it.
I can get pics of it if needed.

if you decide to separate the exhaust from the headers, let me know a price for the exhaust, thanks

oh and i was looking at your sig, i wasnt sure you could do a mini-tub on a 3rd gen...

I'm sure I'd be willing to separate the two. I'd get rid of the exhaust for $650. Most of the cost was in the fab and tubing.

As far as the mini tub goes...the lower control arms are going to be brought in and the panhard rod will be relocated and most likely shortened. Springs and shocks will be converted to coilovers which will also be brought in from their original location. Frame rails will also most likely have to be notched. It will be an involved process.

Very interested in the complete setup.

You said this would clear a spohn x-member, i have his x-member and tq arm with a t56 and hotchkis sfc's. do you think there would be any clearance problems on my camaro?

If not i would most likely pick up the entire setup from you, since youre only a bit north of milwaukee i would come and pick it up from you.

Thanks

I'm not completely sure if it will fit a T56 crossmember. The one I have in there now is for a 700R4. I can possibly call Spohn and ask what the difference is between the two crossmembers. I will be able to get pics tomorrow so you can take a look. The other problem that may arise is the fact that the h-pipe crosses over the 700R4 trans pan. If the trans pans are both roughly in the same position and hang down the same amount, then it might not cause a problem.

I can't get pictures of it on the vehicle because there is no motor in the car right now. All I can tell you is that it hangs no lower than the collectors. The fact that it is oval tubing from the h-pipe to the mufflers, provides a lot of extra clearance. The mufflers are also only 3" thick, as opposed to a Flowmaster Super 40, which is 5" thick. There has to be at least 3" of clearance under the system.

Ok thanks. Also, what are the pipes made of? i.e. aluminized or stainless?

Im sure ride height clearance is find since my car inst lowered, im more concerned with clearance with the x-member and sfc's.

I'm having problems uploading the pics. Do any of you know how to do this? It is saying that my picture files are exceeding the 1mb limit.

These mufflers are very loud. When I rebuild the system, but w/ 3 1/2" tubes, I'm definitely buying the exact same mufflers. They have a very distinct sound. I love it. Different than a Flowmaster, which is becoming too common.

Does spohn think there will be clearance issues?
Ill probably give them a call tomorrow to check if you werent able to.

As long as he thinks there shouldnt be any problems i will buy the entire setup from you.

If that is ok, i would be able to pick it up about two weeks from now.

Do you have any sound clips or videos so i could hear how it sounds?

thanks

I called Spohn today and asked him what his opinion is. He said that a T56 crossmember sits about an 1 1/2" farther back and an 1 1/2" lower. The exhaust system was made to wrap around the outside of the crossmember, so that would probably not interfere. However, the h-pipe might have to be repositioned in order to work with a T56. When it was built, the h-pipe was basicaly placed in under the middle part of the 700R4 pan. If there is only a 1 1/2" difference, it may not be a problem. It is really hard to estimate without mocking it up in the car. If you go to SpinTech's website, they have sound clips that you can listen to. They are not the best quality, but it may give you an idea of what it sounds like. The mufflers are the Eliminator series. They are primarily made for circle-track racing. They are not super loud b/c the exhaust systems for certain types of racing have to be within a certain decibal range.

Sorry I didn't dust off the headers before I took pics. There is also a side profile picture to show how thin the mufflers and oval tubing are.

Here is a close-up of the fab work done to get around the crossmember. There's some burnt tranny fluid on this section.

In the one pic of the headers it looks like the header mounting flange is broke on the passenger side header between the last two tubes. ??

Who did the coating on the headers?

Hooker made that tube a slip tube so installation could be easier. I guess the LS1 style headers are the same way. A local powder and ceramic coating business did it for me. If I remember right it was $125 to coat them.

I'm not familiar with that type of subframe connector. They definitely will clear a Spohn subframe connector. The pipes are so close together that I don't think that they would interfere with any brand of subframe though.

Alston's don't run down the side of the floorpan like most other sfc's. They actually connect the subframes, but they start out slightly inward at the front of the car where the subframes end, and then go diagonally to the rear of the car and attach at the rear subframe in front of the LCA mount.

I could tell you if the exhaust would work if I saw a picture of the underside of your car. From how you described it, it sounds like it might work.

Here's also a link to a thread where someone had his car on a lift and got a better installed pic of the SFC's.

I'm not entirely sure that it will clear. I need to mock it up under my car to see what the clearances are. I will be back at the shop where the car is on tuesday.
