I think the mufflers plug up with soot and go quieter. Mine is definitely not as loud as it was the first week. I remember thinking how loud 18" resonators were and did I make a mistake with this exhaust. I remember the first day driving down town and people were braking necks over the sound.

Now that it is quieter, I sometimes miss that first week and the feeling the sound gave me, but I realize that it was much too loud for daily use.

I am happy with the decision to go with 18's, but I have never heard 12's in real life.

I have 12's and it sounds perfect to me...

there's a great youtube video by a forum member on here with NON-RES Catback installed fully stock with nothing else.

he calls everyone that says it's too loud a bunch of panzies hahaha


from the youtube video it didn't sound that loud so thats why i went NON-RES
also did research with other videos too.

can't wait to get mine

Hizzy, sorry for the late reply....you will be more than satisfied with the alignment, quality is perfection on this exhaust. My tips seem to be perfectly aligned and centered. Its kind of hard to take a level pic with an iPhone but here you go.

As for the sound...I just hit 1k miles on this exhaust, and the sound has gotten deeper, louder and richer for me, again I am non-reso-CF. FI knew what they were doing when they designed it. The best way to describe it is like the porridge is not too hot and not too cold, it is just right!

Pour car wash soap onto a wet microfiber towel and clean them by hand. Once you clean them, spray with water to wash off the soap. Use a dry microfiber towel to dry them off.

Awesome Hawaii, thank you for feedback.

Can't wait to share mine.

Will try to do my best with before & after videos/pics

Thanks Kevin! Btw, they look and sound great!

I couldn't help myself. I just order a new exhaust with Carbon fiber mufflers and the new Prismatic tips. I had to have it. Crazy.

I just added to Tony's pain of being behind.... LOL

YESSSSSSS

Ship notice received. Order #1661 (Next Level Performance sale!)

18 inch res, carbon fiber muffler, regular tips, resonated HFC

will go on at same time as South Bend Stage 2 clutch + DXD lightweight flywheel

hoping for quick angry revs

Which is louder: 12" CBE + res HFC, or 18" CBE + non-res HFC?

I'm 1662😭 Hopefully I get mine soon! It's still saying it's processing :/:mad:

My order number is 1678 and I'm considering modifying my order from stainless to carbon fiber mufflers. I emailed Kevin. Hopefully it's not to late.

Got mine installed this past week. I had flywheel/clutch done at the same time so i couldn't really rip it the way i wanted to, but DAMN the sound is amazing

even around 3k rpm, putting around cruising speeds, there is a noticeable, sharp growl - but its not loud and obnoxious. Then when you floor it, you get the ROAR unleashed

pretty much the perfect exhaust for a street car

Unfortunately one side is not aligned - so the car is back at the shop for a bit more work. Should be no problem

great shot OPTIONZERO :tup:

looks so dope!


no idea where I am on the list.... prob won't see mine until September
