perrin catback resonated - loud enough or too loud?

[Efferalgan]

If you do just the catback and not planning further upgrades of the exhaust - go 2.5'' unresonated. I had one - sounds just perfect when alone. Probably the most balanced and best sounding catback on the market. If you are planning upgrading the rest of the exhaust - take the resonated 2.5''. That's what I did after installing the headers, OP and FT - replaced the mid-pipe to a resonated one.

No any meaningful reason to add weight, rasp and loudness of the 3'' version (and pay more) if you are not planning turbo build with 325-350+ whp.

Can you compare the volume of:

2.5" unresonated CBE
vs.
2.5 resonated CBE + header + OP + FP

Is it much louder with all the additional exhaust mods? Thanks!

Not much louder but adds a bit of rasp (if I correctly understand this word) and other "metallic" sounds from the the exhaust. Also, I have an UEL header - so, there is also "boxer rumble" added.

All in all maybe 10-20% louder than undersonated catback alone but the pattern of sounds is more... rich maybe.

If it was about sound only - I'd keep the Perrin unresonated CBE.

Awesome, thanks. Which UEL header, OP, and FP did you go with?

JDL UEL Header chrome coated and Nameless FP/OP combo with Helmholtz resonator. However, already ordered Motiv OP and FP as the Nameless combo touches the engine block (0 clearance) and I tend to believe that some of those "metallic" sounds are due to this fitment issue.

This was exactly the information I was looking for. Thanks again!

I have a 2.5 non-resonator with catless front pipe from Invidia. I still think that it is not loud enough. I just pressed an order for Borla UEL. Hoping that it will be louder.

No worries - it will be so!

I have a 2.5 with Perrin fp/op combo with resonated midpip. Stock header. Best way to put it. Loud when you want it. Quiet when you need it. Cold starts are loud as hell tho. I always put off an alarm if I'm parked in a garage.

Yes, Perrin stopped making front pipes several months ago due to them not making exhaust components that replace factory emission parts anymore.

Yeah discounted. I purchased mine in 2012. Crazy what you can sell a used one for now.

Anyone out here with the combo of a perrin 3' resonated cat and ft86sf catted UEL?

I see this post is pretty old. I'm also in NorCal and I'm looking at the 2.5 resonated. Have you ever had any issues with the cops and noise around here with the 3' resonated? I want to get this but I don't want issues with a hole cops.

Also do you still have that same catback? Curious what you think after a couple years.
