JJR Dump & CAT

Dodgy 3" J spec steel cat back with big mid muffler and HKS mega can (5" tip with a silencer thing that has never been shoved in).

Its quiet at idle but doesnt really have an RB burble.

I would like to maybe change the mid muffler to get a meatier sound but it's welded in.

I dont want it louder just sound better.

If you think your car is droney, try driving with the boot a little open.

I picked up a door for the house that was too long, it was the loudest trip home with everything being reverberated straight forward into the cabin.

Scotty's dump

Front pipe

Sounds good between 3 and 5, bit droney otherwise, and makes some wierd 'wind exiting cannon' sound at full noise...

Will replace eventually

Just curious if anyone here has actually had their's db tested. Mine is a custom job from about 8 years ago now (previous owner). 3" from turbo back, custom made oval mid (apparently it was meant for a rotary I was told) and some kind of cannon up back. I've never had any attention from the police with it, but they are coming down real hard on anything that even looks modified around my area at the moment. Its not a bad sounding system and far from obnoxious but it does drone a bit and I'm still not sure its completely within db limits (it wouldn't be far over if at all). The canon on the back has seen better days now anyway and I got over the "canon thing" years ago. So I'm thinking of changing the mid and rear. Making the rear some thing oval with twin tips. Will look a bit more inconspicuous. I'm never going to be chasing massive amounts power from this car, one day if I can get up to 200awkw then I'd be happy with that. So I'm still going to keep it all 3" but want it quieter now with less drone. So something internally baffled instead of straight through is probably going to be the way to go. Anyone with a similar setup to this I would like to hear what you've got.

If you get a monster rear muffler (per the pic I posted) then noise will not be an issue even as a straight through.

the one i posted in the youtube vid, is my straight thru system, from 1m away @4k rpm it did 106dB. (thats no cat, no mid muffler, just the end muffler from the HKS hi power silent kit.
now with a 170cell cat, and original HKS hi power system, i did 91dB @4krpm from 1m away.

tested at my mates exhaust shop with the dB reader

Anyone tried dynamiting the boot well area? I noticed there's no sound deadening there would that help getting noise and maybe some drone out?

If anyone has photos post em up! I'm after how big your box size is...

Hi I'm considering upgrading to a custom 3.5" cat back, car making about 450hp, wondering if it would benefit...over my current 3" set up

Pretty vague, there can be substantial differences between 3inch exhausts so how would we know how good yours is?....

Go on dyno , do power run.

Drop exhaust, do power run.

Figure out if you want to make new exhaust.
