Exhaust questions

[sloww5oh]

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

i definitely want more sound than OEM, honestly looking for OEM pitch and sound quality just amplified.

Then the touring will be exactly what you want since you also have catless LTH.
With factory headers, I'm sure the stype sounds really good and the touring sounds basically like stock but maybe a more refined sound. But with LTH it's a different story.

Itl be loud as if you have a loud borla atak or corsa extreme with stock cats. I have the resonator off and have x pipe instead, still sounds stock ish and is very loud but im looking for a different tone so il go s type. However s type will more than likely be way too loud catless for you

Yeah absolutely. Honestly conversations about exhaust systems between catted and catless are two completely different things.

Ya 100% catless makes it a whole new ball game. So final vote
Borla Touring + resonated h pipe in conjunction with the Catless headers

What you want is the Ford Performance kit by Borla with center resonator.

Would that fact the ford performance is 2.5 in diameter, compared to borla's 3 in diameter change the sound that much? I have a ESS kit on the way, don’t know if 3 will be better or not.

Reviews say it's quieter than Borla S-type and very well made. Dunno if there's truly a performance difference between 2.5 and 3.

Ah ok I see. I can get the touring right from the borla website but there are 3 variants differing in price without telling a difference between them. I don’t know if my mobile browser is showing it correctly. Weird

 

[eisenhauer01]

Those differences are probably the three different tips. They have chrome, black chrome, and carbon fiber for your year model pretty sure.

Boost means 3” is better, on 93 you can get away with 2.5 but any more power and you need 3”, but it always adds a few hp to have the bigger size

IRRC, it's been said that the Ford Performance resonator is a mechanical resonator. The Borla one has fiberglass packing. I am boosted with the Borla touring cat back with the addition of the Borla resonator. It's gotten louder and I've seen fiberglass shards on my garage floor. I'm gonna replace it with the Ford Performance by Borla resonator if the actual dimensions of the two are the same.

The Borla resonator has a 2.5" inlet and 3" outlet.

Ah I see. I don’t see any on the Borla website with 3’’ I only see 2.5

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

The smaller pipe keeps the exhaust velocity higher than a larger pipe will, John Lingenfelter used 2 1/2 inch exhaust from Borla making well over 600 horse power, it is all about exhaust velocity, that helps to scavenge the cylinders of spent gases. Bigger is not better when it comes to exhaust you have to figure out the correct size pipe that will result in the highest velocity for maximum performance.

You example about the 2 inch pipe on a 1000 HP engine is mostly correct but the reason they would run a smaller pipe is not for sound but for exhaust gas velocity.

Bigger is not better, exhaust is all about velocity to pull spent gases from the cylinder during the exhaust stroke a larger pipe slows down the velocity and will rob you of power. Borla knows this, that is why they have more wins in professional racing than all the other exhaust manufactures combined.
