single or dual exhaust on turbo engine?
Hi, I have a relatively stock 2.5 engine (but with larger turbo).
I'm wondering what you guys suggest regarding exhaust.
This is going to be mostly a daily driver, with several AutoX and occasional track day car. Sometimes I drive for 9 hours in one 24 hour period.
The province I live in doesn't test for emissions (yet).
My concerns are: power, sound quality (I like a sporty exhaust note, but don't like drone), exhaust odour, aerodynamics and aesthetics.
What I have to play with:
Exiting the turbine is 2.0" pipe that becomes 3" within 12 inches on downpipe.
I have bought 2 "high flow" (400) 3" cats and 2 3" magnaflow tubular mufflers, the entire exhaust will be made from 3" pipe.
Should I go single or dual exhaust?

Single exhaust on my car with 3, 4 and 5 inch all sound fantastic to me.
Try an MBRP resonator. I am going to be trying one out but I am a ways away from getting things back together.

twin exhaust is a waste of time on a single turbo car. 3" turbo back is good.
I had a twin exhaust, but the 2nd was a screamer pipe to the rear. It was cool but got over it.

I would start with a single 3"... also your exhaust exiting the turbine is too small....possibly your turbine is too small. Get rid of that #6 housing!!

3" turbo back, not cat or resonator, no wastegate tie in, wastegate dump pipe, to dual 20" tips. LOUD but I also got silencer inserts for em, since its my daily driver. Turbo wine is alot more noticeable. I also have exhaust popping on de-acceleration and known to pop flames every so often. =)
