Help, need quiet exhaust
 

I have the resonated un-catted 3" Perrin Exhaust and it's got quite noisy. So much so my neighbors are complaining. I need something as quiet as possible but still performance enough to go with my Edelbrock supercharger. And meet Luguna Seca's 92 db noise limit. Any suggestions?

invidia Q300 its resonated mid pipe or similar quiet catback system HKS legamax or legamax sport etc)
and a catted or resonated front pipe (jdl do a quiet dual resonated one)


or similar


2.5 is going to be quieter than 3' in most cases


not sure what the exact noise level will be but it will be way quieter than an unresonated 3" perrin


get your tuner to do the quiet start up mods to tune (if is not a carb tune)

Blitz VS/VSR.

What he said. It's quiet and deep on

Thank you,
My 3" Perrin is resonated.
I didn't know you could tune a quiet start up, that would help a lot.

The q300 is probably your best bet if you want close to oem noise. If you have to have 3" for some reason, it won't be quiet. Are you on stock headers or are you catless?

Top Speed EL header, catless.

bro all you have to do to kill the cold start loudness is put the car in reverse back up a few feet and go forward and boom, no more bitchy neighbors.

@AceHeader-MT is working on an extremely quiet high-flowing exhaust specifically in response to CSG's need to meet noise standards at Laguna Seca. They might be able to help you out.

Then like me, you'll never be quiet. The big sound differences are in the header, pick up a catted header

Plus Q300 and you'll be set

+1 on Invidia Q300

Greddy Supreme SP cat back is nice and quiet too.

isn't the piping on the q300 closer to 2.25 inch vs 2.5?

OP you could also look to find a catted front pipe to help quiet your system down (JDL offers an ultra quiet FP that is catted and resonated). I run a tomei UEL, perrin OP, perrin catting 3inch fp and 3 inch resonated cat back and i don't get any louder than 86db at the track.
