Stillen SEDAN Exhaust - Swapped out the muffler for a Magnaflow
#16
modded stillen exhaust
glad that you have done sth to solve the backpressure problem
Indeed, if you go and do a search, you will see that Tony from
Motordyne Engineering actually did sth similary, but he has used
two high flow mufflers from magnaflow...
Anyways, nice set-up !
I wanna do sth to my stillen catback too..to lower the droning problem..
Btw, is it just me ..or is the PM system not working?
Cheers

On a Turbo setup, I would not keep the X crossover, not much of a point to have it when the it can't scavange. Not really a fan of Magnaflow's X crossover muffler after having looked inside one at the flow path, which is why I ruled out using one for my TD system. Dynomax does offer some nice dual in/out mufflers in their ultraflow line.

How ironic, I went to Mike's Muffler about 5 years ago to have some work done on my Acura Legend.
He did a good job with the exhaust, but he also broke the door lock tab on the driver side, as they were propping themselves on that little piece of plastic trying to get in and out of the car. When I went back the next day, asking them to pay for the repairs, he just tried to get me to go to his "friend," for a "good price."

I didn't do a very good job of writting my post. What I ment to spell out was that I would not keep the Stillen X crossoever just after the cats when running a turbo setup on a turbo charged car. And on the Magnaflow X crossover muffler, I was not happy with the flow path or crossover path inside the muffler body.
Here's a link, click on both ultra flow links on the header.

Gurgen - Thanks for the post! I have heard so many good things about the stillen exhaust, but your pictures are proof and I am re-thinking my decision.
I plan on going the FI route (vortech) and am wondering what you would recommend for exhaust? Its hard to find custom builders here in Iowa (yes, BFE) so a bolt on would be best.
I am thinking more and more about the greddy Evo which says 60-70 mm piping? I wonder if it was designed for the turbo kit? Too bad they don't make an EVo TT like they do for the 240SX
Please suggest. I appreciate your input!

The next one i try after stillen would probably be greddy evo, and make the required modification to it.
There is also the custom route.. Sorry that i can't be more helpful.

Then again, the question is, do oyu really need to have a REALLY wide open exhaust. For best overall performance, yes... but it will also increase the nosie level.

So the Stillen exhaust is dual path all the way to the entry of the muffler and then it's a single pipe through the middle of the muffler and dual exits?
Isn't the magna flow muffler that you put on have a convergence of exhaust flow in the middle of the muffler as well?
20rwhp with just a muffler change? Thats a serious amount of power increase for just swapping a rear muffler. Not saying it's impossible, but I've VERY curious to see what the dyno says. Let us know! I have a magna flow 3" straight through on my turbo volvo and love it!
