Default True Straight Pipe (Cats + Res Delete) Videos/Soundclips

Just got my hands on a backup headerback exhaust system for my EJ22. FIgure what the heck might as well staight pipe it. No restrictions up to the stock muffler. Shouldnt be too loud, ill just get a bigger muffler if it is. Wanted to see if anyone had a video or soundclip that I could use as reference. Preferably EJ22 but any N/A will do the trick.

This is going to be loud. I don't know why you think it won't be and a larger muffler wont help unless its a larger restrictive and sound inhibiting muffler

Resonators don't quiet a car down, they only reduce sound in a certain frequency range.

A catless, non-resonated exhaust is loud, but a large chambered muffler will help. Still much louder than if you keep the cat, but not necessarily ear-splitting.

It's not the "fun" loud, or the "fun but I wish the neighbors didn't have to hear it when I go down my street" loud... It's the "why the hell did I do this" loud.

I have UEL's headers with a trackpipe and any exhaust I have had or have now, I put have double reonsators on the centerpipe.

Without that, any and all exhaust are pretty loud.

I have had turbo xs, greddy, bosal, etc etc.

I now have a 07 wrx axleback for the time being and with the UEL setup, trackpipe and double res centerpipe, i get enough burble to enjoy but not enough to make me want to vomit.

With the greddy TI-c with no silencer, my car was by far louder than most turbo's you would hear and sounded crazy mean but had to sell it. Close to rally car loud.

With the silencer in, it was a nice compromise.

Even with an OEM baffled muffler, my car is still loud-ISH, but not like the other setups.

Loud is an understatement. I've run mine with just a high flow cat and a straight through muffler. It's loud, loud enough to be heard clearly half a mile away. I ended up adding a glass pack (well metal fiber these days) to quiet it down enough to be civil.

I myself would love to swap my trackpipe for a catpipe BUT they are kinda expensive and modifying the trackpipe I have to fit a cat with the 02 spacings would probably cost equal to what a catpipe costs.

I still have my old cat pipe that was good before I put the track pipe in. I'm running UEL, track pipe, then straight pipe to muffler. Ran the car with no muffler for a week to see what it would sound like to. With the muffler(which is on now) sounds like ****. It sounds good around 2k RPM but after 3-4 it gets gross raspy. With no muffler I didn't like the rumble I was getting. I've been trying to find a way to get the loudest rumble available for our NA cars so it can sound very similar to STis. In a few weeks I am going to take the car to my welder and have him weld/make a pipe that will work on my cats and axel back. NA cars with at least cats sound much better then no cats. But correct me if I'm wrong. But it's a little harder for us because we can't have 3" piping or downpipes. I have only heard a few NA's that sound like STi's that's my goal

^^ My car a few months back sounded equal or better to an STI.

Setup at the tim: UEL's, trackpipe, double res STI centerpipe and greddy TI-C axleback. Local turbo guys could not believe how bad ass she sounded, they thought I had swapped. My NA friends also thought I swapped as I did not tell them till after they heard the car.

Hard times forced me to sell the greddy, UGH.

After 10 setups or so, the greddy ti-c was IT!!!!!!! Deep as hell, you were almost able to feel it in your chest.

If I had the money again, I would get another greddy ti-c and leave my setup with that. For now, it's not in the cards as times are tough.

^^ Oh boy you haven't done your reading bad boy, hahaha.

UEL = unequal length headers

Trackpipe = pipe between the centerpipe and headers that DOES NOT HAVE cat converter. Sometimes referred to as a cat delete pipe.

Catpipe = pipe between the centerpipe and headers that has a cat converter

Some visual reading for you

ahh alright, thank you very much! still learning all the abbreviations! So for a track pipe you basicly get a new pipe/remove the cats in the up-pipe, and down-pipe, right?

Also i currently have a cat back exhaust and was thinking about getting a new piping up to and including the headers. i am gonna try to get a cat less up-pipe and down-pipe. I'm going to get a cheaper down-pipe that replaces the mid-pipe. Do you think i can cut off the cat from the mid-pipe(Stock 2") and weld that on the new down pipe(3"), or would it not be that loud/pass emissions? . Do you think 2 resinators will help with the noise, or will it just help on highway and such? Lastly what is your option on a bellmoulth for a down pipe, how nice do they flow/sound compared to the other types? Is it that big of a difference separated?
