muffler question for tvrolet and terminator
Discussion
I pressume you guys are running mufflers to meet track noise levels and would be interested in what your running.(95 dba in NZ)
Ill be routing my exhaust and muffler very similar to the tuscans and changing my bottom door hinge points to end up with roughly a 250 x 150 mm sill cavity.
Have you guys looked into mufflers yet for your projects?
I was going to run a flowmaster 40 series(3 inch inlet and outlet) behind the rad but space for the bends is starting to get tight and heat soak may be a issue,hence going for the tuscan type sill cavity.(the flowmaster is to big for the sill cavity)
The trouble is there are so many slim round and oval types out there I dont know where to start,and I dont wont to rob to much hp.
Id be interested to see where your at with this.

Sorry - can't help too much in the way of answers, but I've got questions here too!
I'm using the standard Tuscan silencer - the one under the door, plus I'm using headers that connect to the standard Tuscan 4-1 collectors. In therory then, the standard downpipes should fit....bit they don't! Bit of cutting and welding required therefore.
However....and here's my question: the standard downpipes have two 'cherry-bomb' style silencers each before the final silencer i.e.the race Tucans have 4 'cherry-bombs' and 1 huge box in all. I was plotting leaving these off and just running straight-through pipes to the main silencer, as I guessed the Chevy would be a bit more fruity that the AJP.
Terminator - aren't you just running a single silencer without anything on the downpipes? How loud is that, as mine will do track days.
Noise isn't quite such an issue for me, as most track outings would be at Knockhill, where there are no noise police
, plus the TVR sessions are usually 'noisy' too. The real noise-restricted circuits like Bedford are maybe 350+ miles from me, so no real incentive to make it extra quiet.
What I am interested in knowing also is how do they measure noise from a side exit exhaust? You're obviously going to be disadvantaged on a drive-by if the mic is on the left, but advangaged if it's on the right. Do they compensate for this?
Also, how do they do the static test? I know for rear pipes its at an angle (45 degrees IIRC), but is it 45 degrees for side pipes too? And 45 degrees forward or backward, and 45 degrees to the pipe angle or 45 degrees to the gas flow?
Sorry I can't help with noise levels, but it would be really neat to know how they measure on side-exit pipes.
