So I'm planning to buy a universal magnaflow muffler and fabricate the pipes at a shop. But the thing is I don't know how to place the muffler. What would be the proper way of installing the muffler? Is it:

like this

or

like this?

It would be neat to install it just like the second diagram(OEM look). But one of the actual outlets will be used as an inlet(and the muffler inlet would be used as an outlet), which(I THINK) would disturb airflow because of the chamber inside and so, one of the tips would be blowing less air than the other.

Any idea on how to go about this :dunno:

And please don't mind the crappy pipe drawing...

If u want a proper exhaust for the 2.0t, then get 2 mufflers, each with 1 in and 1 out so u can make a Y pipe. This is the only way ur gonna make a true duel exhaust for the turbo.

I would use this and place it like the stock muffler....

Unfortunately, there is no real dual exhaust setup for any 4cyl.

ok a semi duel exhaust setup. Still gotta get that Y pipe setup.

From Magnaflow, proper one for the 3.8 is #12265, which I just ordered. Is the 2.0T the same set-up and diameter piping?

the first way

If you read up about Magnaflow mufflers you will see that they are not a chambered muffler meaning you can use either end as the inlet or outlet. I have mine setup exactly like the second picture. Sounds great and along with a secondary cat delete i could feel the engine being able to breath much easier. I ordered the muffler, J bend pipe, two 90 degree pipes, exhaust flange, quad polished tips, and two hangers all for around $300 and take into account the tips were 120 of that....beats the hell outta 7-800 at the least for the magnaflow catback. the testpipe I ordered on ebay also for around 40 bucks.

I ended up getting a magnaflow muffler P/N 12266. The outlet on the left is placed in line with the one on the right. I have a secondary cat delete as well. I just hate the sound that the exhaust makes sometimes when the gear shifts from 1st to 2nd(rasp) when stepping on the gas hard and shifting at the same time. Has anybody used this to suppress raspiness:

Vibrant Performance ::.

I think that this would give the exhaust a much cleaner and smoother sound.

#12266 is 2.5 inch inlet and 2.25 inch outlet. I thought the piping for all Gen Coupes was 2.5 inches, which is why I got #12265?

I would like to know this as well. What is the size of the pipes going from the muffler to the tips...2.5" or 2.25"??? If 2.5", what difference would it make to get the 2.25" outlet muffler?

I'm trying to eliminate all Rasp..would 2.5" be better or worse than 2.25" for that? Thanks folks!
