I'll be heading down this path soon. About $200 at the Jobber got me 7.5' of 2", 2 J pipes, a Y pipe, and a walker 22105 Quiet-Flow muffler... I'll still need some hangers and clamps, but it should be enough to get it going. It won't win at the dragstrip... but should flow enough for 200 Hp.


Here the muffler shops would want $1200 or even more :(

Ouch!! Bring it to me, I'll do it for $250 :-)

Best of luck!!

Cheers!
 
I had a local exhaust shop run the exhaust off the Y pipe for $180.

I was quoted $700-800 for an exhaust system for the Gt6 Triumph I had. I built it out of Curiser rear hoops... a 90, 5' pipe, a 45, a $30 Turbo muffler, and a turndown...<$50 and a couple hours... a muffler shop could have it done in an hour (counting a coffee break or two).

Guy at the parts store said a Chevelle exhaust is now $1200 installed.
 
Well another day and some more progress. I welded things back together. I thought about just tack welding at first and then a trial fit but got lazy or in a hurry, I'll let you decide :).

After cleaning up the welds I went back under and much to my pleasure this time it fit like a bug in a rug.

There is about 1" clearance between the top of the crossover pipe and the pan. There is also about 1" clearance between the back of the crossover pipe and the pan.

There is enough room to put a thermal barrier over the pipe to keep most of the heat off the pan. I'm a little more concerned with the 1" or so of clearance with the front drive shaft. I'm going to play it by ear for now but one of my thoughts is to space down the axle bump stop to prevent any impact between the drive shaft and exhaust.

I know it may not look it but there is actually 1/4" clearance with the oil filter. I already run an oil cooler but may also put a thermal barrier around the pipes and 2 into 1 collector.

As you can see it tucks up nicely above the bottom of the frame rail and there was just enough room to thread the wide band O2 sensor in.

I am going to paint the whole assembly with the same paint I used on the exhaust manifolds. So other than the paint my downpipes are complete for now. The next step will be plumbing the 3-1/2" exhaust back and out behind the drivers side rear wheel.

Any update on how it all was finished? Sound? Pipe routing out the back? Pics!?
About to dive into mine, your setup is one of the best I've found! Nice work!!
