Exhaust questions

[sloww5oh]

I went opposite, more quiet. Long Tubes, no cats, stock resonator, stock cat back and the car still made close to 800HP. Goes to show, those catbacks don't add power, it's just noise. The power is gained in the headers and cat area.

Pretty sure I follow this dude on Instagram. I'm sn95_mustang_garage on Instagram if you want to hear my car. I do a bunch of cold start videos.

you do follow me! Thx for the follow! Trying to grow my car page to new heights given that Canada needs a much better car culture haha

AWE or what I just installed from Thermal R&D (3" full cat-back, with 3" connection, 304 stainless, VERY DEEP TONE). I don't have headers, but people say with headers it has a much better sound than others. I was recommended the Borla S-Type, but let me tell you, that exhaust is L-O-U-D even with stock headers/cats, let alone catless headers. The S-type will blow your ears up. It's more of a resonation change with no sound suppression. The Thermal R&D actually has a 3-chamber muffler in the center, and the rears are straight-through Helholtz resonators (no packing).

That sounds nice! I have the active exhaust, I don’t know if awe has anything valved. Is your setup valved?

No mine is non-active, unfortunately. I think AWE makes both, but not sure.

I did the Borla Switchfire. Very nice tone. Mine is stock otherwise. Switchfire is like a x pipe and H pipe combo

I went down this road as well..
15 GT with catless LTH.

Originally, had and x-pipe with Ford Racing by Borla axle backs.
Way too loud, way too much rasp.

Next, I welded in Vibrant bottle style resonators in behind the X.
It toned it down, but it was still loud and raspy. I tolerated it with that setup for a couple years.

Next, I wanted to actually make it sound good. So I bought a Magnaflow 11386 dual inlet/outlet muffler. I cut out the X, and put this in its place. The Vibrants were still in place, along with the axle backs. It got rid of the rasp almost completely, but made the car almost silent.
I didn't think it would have been possible to make the car "too quiet" having catless lth's, but this thing did just that. It did not have a good clean sound, and I wasn't in love with it at all.

All of the above was done with cost in mind, and I ended up not happy with the results.

A week after trying the Magnaflow piece, I bit the bullet.
I bought the full Borla Touring Cat Back 140589BC system. This has the resonator and black chrome tips. The sound is amazing. It sounds exactly how it should.
It has a nice deep v8 rumble and growl, with zero rasp.
When you open it up, still no rasp at all, just straight performance sound.
The car is not quiet. It gets loud without being obnoxious. Can't praise it enough.

Honestly, I saw several people saying the s-type would be the way to go with LTH.
I thought about doing that, but after being on the "too loud, too raspy" road for so long, I was over it. So I went with the touring system, and crossed my fingers that it would not be "too" quiet.
I can say with 100% certainty, this system is everything I wanted. Not too loud, not too quiet, tone is perfect, no rasp. I wish I would have done it years ago instead of screwing around to save a buck. Just my $.02

I feel like if you're gonna go all in on a full cat-back, just do the 3" ... doesn't cost more and prepares for future if necessary. The idea that you "need back pressure" is fairly silly, especially on 7,000rpm+ engines like these, where there's not a ton of low end power anyway.

Its not just back pressure people go smaller diameter. Currently i have a touring muffler from borla with a 2.5” catback cuz i wanted to quiet the car down. I had it way way way too loud with an armytrix catback, which somehow is louder than corsa extremes imo, and will be going back to 3” with a borla s type. Smaller diameter pipe works well with lower hp setups, make the pipe 4” on a honda with 200hp, you get a god awful sound from the exhaust. Same with a 2” exhaust on a 1000hp, sound also similarly gets better with a proper diameter pipe for the hp

excellent, so your saying borla touring with h pipe and the Catless headers is the move?

 

[eisenhauer01]

Yeah. In my opinion 100%.
You say "with an h pipe", and just to clarify, the Borla Touring system has a resonator that contains an H inside of it. They offer it with different color tips (black chrome, chrome, carbon fiber, etc..).
Here is a pic of the system I bought from Beefcake. I finally love the way my car sounds.

Change to an h-pipe and get rid of corsa. Borla and MBRP (street series) seem to have a decent tone.

I am catless headers, h-pipe, mbrp street mufflers and its definitely loud but not super obnoxious and it doesn't drone or have lots of rasp. Corsa mufflers aren't even mufflers haha.

OP, AWE does not make an active exhaust for S550. They have a bracket for the actuators so you don’t get a code or light on the dash but it’s a passive system. If you want to retain the active feature, go Borla.

 

[ZeroTX]

ahhh I see, I sold my factory resonator what do you think of borla h pipe resonated with s type ?

S-Type full catback comes with an X-pipe, no resonator at all. There's a resonator you can buy from Borla for another 600 bucks, but you can't order the S-Type catback with it, you have to buy both, so it costs a ton. Huge fail on Borla's part, IMO....

That said, you can call them and order the parts one by one. Resonator, over-axle pipes, and rear section. You'll have to order directly from Borla and speak to a salesman to get all the right part numbers. It isn't available that way as a kit.

someone above said the touring comes with a resonated h pipe, honestly leaning this way as Corsa catless headers make the exhaust so loud.

Want deep, go borla type s w/ the res

 

[eisenhauer01]

I'd be interested in hearing the difference between the s-type with adding the borla resonator, and the touring (like mine) that comes with the resonator. Because mine is deep. I can't see the s-type making it any deeper. I can see it being louder, if that's what your after.

The s type to the touring is louder but its also a more aftermarket type of sound, a touring sounds very similar to oem mufflers
