That's good to know. I think I will hold off on getting a new muffler until I can hear some better results.

I am going to try and use an old FD Trust muffler that my FD came with... It fits just about perfect... but it's super old and sounds like there is a bunch of acorns rolling around inside.

My exhaust system will be 3" all the way out with V-bands and consist of a Down pipe --> Mid pipe(ends right before diff) ---> Exit

The mid pipe will be straight all the way back so that I can easily add any other thing in the future (resonator/cutout w/e). Then basically a little pig-tail twirly exit with a muffler.

Any experience with a Jones?

I am noob at muffler brands. I've only ever heard of Magnaflow, Monsterflow, and Flowmaster. Haha :noob:

Ended up going with a Jones muffler from Summit. I had a 3" turn down I bought from autozone probably 5 years ago... so I made some pie cuts and turned it out 90*.

I was able to stick to the exhaust being a 3 piece like I wanted to make.

The middle section is completely straight so adding in a flex piece or resonator at some point is an easy task.

Ground clearance... tucked under frame rails.

Made the final piece today. The exit. Hangars are always a pain for me to eyeball just right, but I was able to do it perfectly this time.

This pic makes it look not centered, but it's just the angle of the camera.

So after starting it up, I can REALLY hear the exhaust leak in the engine bay now. Unfortunately it looks to be cylinder 1 manifold flange to the head. I am slowly tightening down the nuts to hopefully seal it up, but I worry I am going to shear a stud.

FUCK!

The last thing I want to do is take off the entire exhaust manifold again... If I do that, I might as well make a non-log style manifold and start over.

All I want to do is start tuning with the MS3 and driving :cry:

Haven't been updating this much, but plenty of work done.

My problem was that the timing gears were both off by about 1-2 teeth somehow. Now it runs good.

I have been tuning the fuel maps and idle mostly and sorting things out. I hope to take it to the autox this weekend, but damn the tires and suspension are absolutely terrible.

The car pulls surprisingly strong for only ~7psi, I am working on tuning the EBC now to run more boost with the flick of a switch.

I hope to post some datalogs and my map tonight for review.

i think the tittle of this post is misleading...
this in no way will be a high MPG car....at least not anymore

and updates without pictures are wortheless

Very true. The scope of the project changed and I went a different direction. Hypermiling is only cool for so long... Not sure if I can change the title.

About to list it for sale.
