Hi, guys this is Jason with Enthuzacar. I am looking to build a 3" exhaust for the 99-05 turbo miata and would like to get some of your ideas and imput for the design of the Exhaust. Single? Dual? loud? stealthy? ect.. Any imput would be greatly appreciated. Jason

singe factory exit. Tip should be same size as the exhaust piping and be made to look like the factory tip.

I want single exit in the stock location, but not with a factory tip. I would want more like a 4" tip because that's what i have now and I like the look of it. I don't want something very loud because I don't run a cat and don't want the extra attention loud exhaust creates. It seems most people run their 3" system under instead of close to the axle. Is that what you plan to do as well?

Single, stealthy/quiet/resonated, v-band clamps, 4 inch max tip diameter!

feel free to copy mine.

it's a 22" long magnaflow perf core center-offset 9x5 I think.

all of the above.


BTW, I keep hearing that you made a 2.5" NA dual exit....did I hear correctly?

I really like the idea of using v-bands. I was planning on making my own and vbands were going to be a requirement as well.

Scott, there's at least one 3" Enthuza dual exit for the NA running on Bochinam's twin-charged car.

if the NA and NB designs were flanged at the diff, then the last section could be a universal fit, allowing the buyer to choose a muffler and exit style

Thanks for the input. I like the idea about the v-band clamps. I have built a couple of these ehausts with them. It is a nice way to change out a Cat or test pipe for the track or autocross. I have a 3" dual for the NA miata. I don't really advertise it because it is really only for the turbo cars (were the minority).
The only problem I see with the universal fit is the hanger locations. The NA and NB are completely different. I just got some ultra high flow metal cats and I will be working on NA replacement cats up to 3" this weekend. Jason

do you have any pics of the 3inch duals.

RusMan

medium loudness, driver side exit, 3-4" tip, v-banded.
That's what I was looking for in an exhaust but due to no availability had to make a custom one, but made mine very loud

Turbopezz, check the link I posted above.

only problem with V-bands is price. consider a swappable cat version and a standard version with a permanent cat to save $100 on the two clamps.

are the cats the metalcat brand? or what?

Enthuza

They are not the Metal cat brand. I like them but, their expensive. Maybe after they get more resellers in the US the price will come down.
I was amazed how much these metal cats flow considering the size and weight. I am considering the swappable version as a additional option. The standard version will bolt or weld in place. Jason
