I'll pop in to say the exhaust looks killer. Very nice.


Do you have more pics of the downpipe setup? Looks interesting from what I can see there..

Yeah, that's my brother's SL4. Stock drivetrain but a killer suspension. He hangs with my miata in some twisties!

Word. I did it mostly because of you, or at least I think it was you. Someone replaced their flowmaster with a cheap-o turbo muffler and gained some power. I always heard rumors about the bad flow of flowmasters on turbo 4bangers but that modivated me to get off my *** and start researching what I wanted to do. Plus I'm building an MSM exhaust in a few weeks so I wanted to practice on my car first.

Yeah, the old muffler was a standard 2 chamber flowmaster, circa 2000. This was before the large cases or deltaflows existed.

I am going to keep this setup and dyno it at the miataturbo dyno day in a few weeks. I will attempt to run the same boost for a run (9-10psi) to see what the exhaust has given me. However, I am now making 3-4 more psi with this exhaust than I was with the old exhaust. I was running around 11-12, now I'm hitting boost cut at 15psi. It's detonating a little after shifts, I have to adjust accel fuel i'm sure and probably add fuel everywhere.

Wow - sounds like huge gains already. And I'm sure that new cat makes a big diff on flow. 3" helps huge when your exhaust is cluttered with mufflers and cats. Detonation after shifts- meaning as you enter the next gear and load/torque starts? You're running a link? or something else?

In the words of Borat, "Thats Nice"! Looks killer Tim. I keep telling myself I'm going to have to make one one of these days. Sound Clip!!

Yes, after load/torque starts, and around 6psi. I'm running the AEM EMS. It should be simple to fix. I'm just lazy.

note to self: you too can have a sweet exhaust like this after buying a welder and taking some lessons.

On second thought, let me know when you start selling these things.

I <3 3inch exhausts... even my beater/daily has one . Miata will definitly be recieving one... wait til you see my poor rear bumper when I'm done.

Looks like a very nice piece though Tim.
