Interesting... My mate's got an A70 with a cat, Redback sausage roll and muffler, all in 3", and it's just fine.
cock and bull it will.Originally Posted by thechuckster
ive got 3" from stock dumps back, resonator under the drivers seat, and an offset muffler in the rear with 5Zigen Tip (not that it makes much difference i dont think?)
mines as droney as fuck.
ive considered and inquired about a cat, and what it would do for the exhaust, as i love the note, and its not too loud, it just drones like a whore, and ive been told CAT wont do much in terms of drone.
i cant think of a single way to get rid of it, as the resonator did precisely dick all.
stupid 1J + A70 cabin drone.

EldarO, my experience with hotdog resonators is the same..... they do fk all.
I fitted a Cat to my previous car also to see if it would kill some resonance, but made no difference.
MrShin: The hooker aero chamber is about $160, double what the Redback cost to do the same job![]()
Ive got some big ass cannons on my otherwise stock system.
Real droney as 2K3 RPM. On boost it goes real quiet and you cant hear it over the turbos.
Im going to put the stockies back on for a while I think.
HZJ75, RS41, JZZ30
CAT wont eliminate drone, a hot dog 'should' reduce drone as it provides expansion space for the standing waves (the drone sound) to eliminate. Either it's not big enough, the internal perforated pipe has been damaged or the outer section has been filed with something too hard... however, every *A70 i've ever seen has droned - maybe it's a factory feature![]()
My Blitz NUR drones like a MOFO. Flows like a MOFO too but yeah real fkn annoying on a 6 hour road trip(JZA70) But a mate has an RS*R one on his JZA70 and its so fkn quite its freaky. Although he has a shit restrictive cat in there, 3" every where else tho.
I was thinking of buildoing a custom twin 2.5" with a pair of glass packed dogs. I want a deep roar on wot and high RPM and a nice deep NON DRONIE sound on idel and low RPM.
For what it's worth, I had a 5in. Apexi muffler on my A70 and it had the most awesome idle ever. Really deep and pleasant sounding. I think the size of the muffler has a direct relationship to noise levels because my car was a lot quieter than guys with smaller mufflers ( 3in. for example ).
sounds like a smart person to meOriginally Posted by ReQuieM
1JZ-Rolla, every JZA70 ive been in is loud and annoying, even the stock systems that ive heard drone too.
and here i am wanting to rip out the sound deadening to save weight
im beginning to give up hope.
chuckster, the hotdog was put on at the same time as 1J, which means about 4 months, and 3,750 k's of use. and if the guy installing it buggered it up while he did, id imagine he'd get alot less business than he currently does, i managed to fit a booking in 3 days, as hes now a mate, and he managed to fit me in... (barely)
in short. teh JZA70 exhaust sounds like dick.

Hey mate the best thing to do is go to your performance zorst shop and ask for their advise. they would have had lots of other people ask similar questions about other high ouput engines.
az
That's alright if your exhaust shop is actually any good...
... must resist..... must resist urge to say something about *A70 owners and dicks...Originally Posted by EldarO
