muffler suggestions?

[raptorWagon]

I wanted to see just how "straight through" my muffler was when it arrived, looked in the inlet and could see my floor out the other end perfectly. That's straight enough for me. I wasn't a fan of the "Coffee Cans", or angled exhaust, those stand out too much imo.

I picked it up cause it was a 3" mandrel bent catback for less than what my local muffler shop was gonna charge for a crush bent. I wanted a dual tip, but we'll see how this goes for now.

 

I'm torn between a Magnaflow 3 Chamber XL, and the dual tip vibrant.

 

Vibrant. Dont get a chambered muffler on a turbo car.

 

Im having really bad boost creep issues and I have a dump. So I need some type of restriction.

^Id look at you wastegate first^

+1 for wastegate. Do you have an internal gate? Cause we could port it out to 34mm. I have an extra flapper to do so if need be. OR you could REALLY fix it with an external wastegate. /ubbthreads/images/graemlins/dunno.gif

 

Its internal. Porting it is probably a good idea, thats next on the list after muffler. Once I move.

^+1. There is a reason all the major manufacturers use straight through design mufflers in their cat back systems for turbo applications....for example, the A'Pexi World Sport line. For NA apps, you got a chambered muffler, and for Turbo apps, straight through. On NA cars the chambered design helps to increase the low and mid-range power. On turbo cars, the less restriction the better.

I'm personally using a magnaflow oval, straight through design. Sounds great.

Skip the chambered muffler. Port the turbine housing first and then get a good straight-through design muffler.

Heres a clip of a solo run at the track click

3" inline Magnaflow and 3" in 3" out Magnaflow out the ack with a twin 2.5" tip welded on. The shop did a great job to get everything tucked away with only the tips being visible.

+1 and +2 on the Magnaflow straight through. They sound awesome. Though mine is 2.5" in and dual 2" out, I plan to stick with Magnaflow when I go 3"

 

[turbowop]

My Magnaflow is 3" in and dual 2.25" or 2.5" out. I can't remember which. The oval shape of the muffler helps to tuck it under the car better, which looks much cleaner from the side since you can't see it hanging down.

That looks awesome and fills the bumper nicely! I like the tips. Magnaflow FTW!

 

If I had a bit more cash I would of purchased that same Magnaflow. So went with the vibrant 1149 black dual tip instead.
