Friend from NZ was telling me about his plan for an Mx5 exhaust. Sounded interesting enough to post, so I asked him to take pics. Definitely an option I'm considering in the future. I think that's a 13" can on that muff - but I like the idea of getting the spare under the trunk w/o having to cut out the skin. Mine is that way because my bumper was already trashed from being rear-ended (yes I kept the cash - spent it on racing :gay. - rob

 

one more

 

that's different.

why the need for two resonators though? i think a langer resonator in the midpipe would have the same effect at what he's doing, then you would have more room in the rear subframe area with just tubing.

 

The red one looks more like a cherry bomb muffler than a resonator

 

it's being used as a resonator on that system. i used a 4" bullet muffle (cherry bomb) as a resonator on the midpipe. Bruce has this exhaust now.

 

lol i "just" run a cherry bomb, sounds pretty bitchin ... not even that loud with a turbo.

 

He wanted it quiet-er, like me. I'm running a turbo muff AND an 18" glasspack. What I like about the quiet exhaust is how easy it is to hear the turbo spool up. Sounds wicked.

 

i run the dynomax bullet race muffler. pretty much the same thing but... not red.

are the cherry bombs perfed or louvered?

 

probably- they're cheap and every cheap glasspack I've seen is louvered. Bell mentions running them the "wrong" way in a turbo set so the louveres don't scoop the flow, but then they don't work as well. Mine is the right way. My thinking was that an entire 3" exhaust would compensate for some of the other inefficiencies.

 

how loud are these cars with 3"? Do I really need a muffler with 3" after the turbo?

 

A restrictive exhaust will rob you of more power than you can imagine. Just look at my 15psi dyno. I was being robbed of a minimum 30whp. Sadly I got too aggressive with my tune and have fux0rd my engine.

 

heres my exhaust setup (note the can of fixaflat ... well its paint but just pretend)

 

a 3" resonated exhaust with a decent muffler isn't loud at all. way quieter than any "quiet" N/A system. For example: my car stock with the whole goodwin head to tip exhaust, cat, resonated, and the super silencer tip is WAY louder than it was with the 3 inch exhaust and turbo.

how much are those cherry bombs? the perf core 'resonator' i run was like $35.

 

my 3" in/out at 18" long was $30 delivered from summit

 

I always thought the idea of two 4" x 18" round Magnaflows would be cool, then dumping out the driver side.



Or even going as far as fitting 3 up there for ultra stealth...I really hate loud exhausts.

 

today mine is a like this
=[muffler]=|======|{cat}|===(turbo)

tonight it will be
=======|======|{cat}|===(turbo)

next time I go to the shop it will be
=======|======|===|===(turbo)

<--- likes loud exhausts

 

they aren't quiet enough. that's why I swapped out my 12" dynomax ultra flo welded for a ginormous 22" long magnaflow.




The top is stock. The bottom is the ultra-flo welded dynomax.

the current muffler is bigger. it got rid of the 3000 rpm drone on the freeway. very livable.

 

3000 rpm on the freeway?

...

I'm at more like 4.5

 

traffic? expressway? freeways around here are all 55 max?

 

I need some of that in my life.
