yeah it is hella different the HB is like a Glasspack style resonator minus the glass it just has packing. and the Sedan Res. is hella wide and big and looks very restricting.

Julio Bro!

So hwb90, does that means you cut the pipe to see inside the resonator?

Even if it's packing, it's still straight-thru, right?

Which exhaust are you talking about sedan or hb? The hb looks more like a glass pack. The Sedan is still straight through but it's REALLY wide. making it quieter. Me and Izzyidk have done multiple exhaust set up with the stock piping he has a HB while I have the Sedan. When we both were Straight I had a Deeper grumble with like a GTO rasp while he had grumble with a higher pitch rasp. with just a Resonator delete I was Louder then him but both where deep. when I got a Thrush Glasspack put into my straight pipe it still stayed loud and deep. toned it down very little. While Izzy's hatchback got a lot quieter but he had a Cherry Bomb Glasspacks. I dont have exact measurements on the Aftermarket Glasspacks though but can get some if someone wanted to go that route. also Izzy now has a 3" Non Resonated Catback with a Tsudo Muffler REALLY deep and little drone. I have not tryed this yet since its going to cost me a bit more due to 2 cans and a Y pipe. If you need me to clarify anything feel free to ask.

Mine is 2009 hatchback. I just wanna know if you saw the resonator inside and confirmed that it's a straight-thru.

And what about internal diameter, is it smaller than the rest of the OEM pipe or stays the same?

The Resonator is a straight through and the piping looks like it stays the same.

Julio Bro!

You see, that's very cool, because the piping on the turbo models is already quite big from factory and bends are very smooth. Which means that to free up the system, you just need to replace the muffler for whatever you like.

I'm looking forward to a Hushpower from Flowmaster; I had a good experience with one on a 240SX. It's not completely free-flow, but the conical "chamber" is a mesh, which provides for a near-free flow with a lot less droning. I hope the sound is good.

Why are you guys spending so much time messing with the factory exhaust system? It is unbelievably easy to just get and install an aftermarket catback.

Julio Bro!

Money is a great factor to think about. If the OEM layout is good, why spend $500 or $700, if you can do with $200?

The savings could go to a new downpipe or other stuff.

Exactly what Julio said. Also I wanted to see what the stock exhaust was capable of sound wise. It seemed like so far what i've done has given me more power and I like it how it is. And I've only spent like 140 or w.e for all the things I've done.

Compare an oem midpipe to a SPT and the difference is huge. At the Y for the sedan, the pipe diameter reduces at the spilt. Hard to believe you guys saying the oem midpipe is sufficient no matter what reasoning you use.

I got the Y remade in the Sedan. Also I wanted Sound not Performance which I achieved very well.

Julio Bro!

The wagon is different, it's a single pipe all the way with a good diameter and a straight thru resonator. Apparently the big restriction is the muffler alone.

I know ive dealt with both.
