It's got some grunt to it. I have a complete catless system. 2.5" downpipe, 3" exhaust, 2.5" dual exit pipes.

Rear now has two magnaflow staright-thru race mufflers on each exit pipe now, and one 3" resonator in the mid pipe.



Cell phone video. It doesn't really do it justice.

Here's how it looks... before it was finished.


I want to cut down the 2.5" pipe and add more 3" in there. I know more can fit.

 

If I could weld I would be more picky... lol. But I do agree.

That's where I'm hoping I can start the 3" pipe whenever I get a chance to take it back in to the shop.

 

I'm not finished, and I live in So Cal. This isn't my first rodeo. lol. If I need to drive in inclement weather that tube can be pulled out in less than 30 seconds.

 

Thanks......

It's a prototype... so not finished.

It's a 3.5" flange on that filter merged into a 3" tube.

 

Did some measuring and readjusting to fit a better filter.

I didn't want to spend $50+ on a filter that didn't fit, hence the foam filter as a temporary place holder.

Picked up a K&N filter recently. Here's how it came out.

Tight fit, but it fit.

 

There is some drone, but nothing too extreme. With a little music it's definitely tolerable for passengers. I enjoy the music of the engine.

If i wanted to cut down the noise more (which I might), I could add one or two of the 3" style Magnaflow race mufflers in the mid pipe, and take out the resonator. Those mufflers area little beasts.

This is the muffler on the exit pipes: Magnaflow 2.5" Race Series part ##14156.

No issues as of yet, as far as welds go. The custom system has been on the car for about 8 months now.

 

It's 2.5" DP, to 2.5" under the transfer case, then turns 3" after that.

3" could fit, but it would be pretty low, maybe with a good solid aluminum under tray. Now I know why the WRC car runs the DP/exhaust over the trans, to under the car.
