ADD Posted September 26, 2007 Share Posted September 26, 2007 howdy all, ive been running the car with the baffle in the exhaust recently coz the neighbours arent happy wit the noise at night, the differenct in power and response is madness... does anybody else use their's with a baffle, if so do you get the same results as me???

rovervi Posted September 26, 2007 Share Posted September 26, 2007 i run with the baffle in but i am not turbo so the power gain isnt that noticeable anyway. I dont really notice a power loss in fact i sometimes think the baffle improves low down response keeps the letters from the council away though Quote Link to comment Share on other sites More sharing options...
Dazzi Posted September 26, 2007 Share Posted September 26, 2007 Same here with an NA. Baffle makes a difference with the noise but can't say I see an increase in performance. I did a little vid to compare baffle vs no baffle Quote Link to comment Share on other sites More sharing options...
dr_blackman Posted September 26, 2007 Share Posted September 26, 2007 I'm running with the baffle to on my na. I think they rev better without to be fair Bloody loud though hence baffle in, specially as I start silly early in the morns Quote Link to comment Share on other sites More sharing options...

ADD Posted September 26, 2007 Author Share Posted September 26, 2007 Oh it seems only the N/A boys use them, mind you an N/A full Decatt and a nur spec has gotta be uber loud... Quote Link to comment Share on other sites More sharing options...
zap Posted September 26, 2007 Share Posted September 26, 2007 Only use ours on long droning motorway trips. Quote Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted September 26, 2007 Share Posted September 26, 2007 Made a baffle for my old system, found it took 50 BHP away:( i now use an Apexi ECV. Quote Link to comment Share on other sites More sharing options...
ADD Posted September 26, 2007 Author Share Posted September 26, 2007 Made a baffle for my old system, found it took 50 BHP away:( i now use an Apexi ECV. yeah it certanly restricts the power!!!!! but it can easily come out.... Quote Link to comment Share on other sites More sharing options...
ivan Posted September 27, 2007 Share Posted September 27, 2007 Mine restricts power AND makes an unbearable noise. If I try to accelerate with it in the exhaust screeches like a scalded cat. Quote Link to comment Share on other sites More sharing options...
DaveM Posted September 27, 2007 Share Posted September 27, 2007 I've had the baffle in my NUR Spec for a couple of years now. The car definately feels a little more sluggish to drive so it would not surprise me if I was losing some power by using it. It does quieten the car down a lot and I have been thinking of removing it again recently but I think I am likely to get complaints from the wife.

Scoboblio Posted September 27, 2007 Share Posted September 27, 2007 I've got a nurspec and put my baffle in recently for a long journey - I loved it. I'd forgotten what a quiet, comfortable well behaved cruiser the Supra can be. Unfortunately I think I've buggered up the screw so it doesn't tighten properly any more. Time to get a replacement I think! Quote Link to comment Share on other sites More sharing options...

bignum Posted September 27, 2007 Share Posted September 27, 2007 I put mine in for long journeys, i cant stand the drone at 80 on the mway, and for trackdays i normally fail the noise test without it. Quote Link to comment Share on other sites More sharing options...
DaveM Posted September 28, 2007 Share Posted September 28, 2007 Removed my baffle last night and drove into work today without it. The car definately feels livelier and sounded absolutely wonderful (I had forgotten how good it sounds without the baffle). Unfortunately the wonderful sound of the exhaust was being spoilt by the nagging sound coming from the passenger seat so I expect that the baffle will be going back in over the weekend.

b_have Posted September 28, 2007 Share Posted September 28, 2007 Made a baffle for my old system, found it took 50 BHP away:( i now use an Apexi ECV. How do you find that? I'm in the process of fitting mine, but was in two minds wether to drill the butterfly, as I'm a little concerned about excessive backpressure. Have you adjusted yours to close half way or more?

Branners Posted September 28, 2007 Share Posted September 28, 2007 I run with a baffle in mine all the time and my wife still complains that the car is too loud. I have not run the car mapped on the t-61 without the baffle so not sure how much power it has dropped. But on I did find that the baffle dropped boost by about 1psi on my old import. One member many moons ago drilled holes in the baffle to slghtly increase the noise and improve performance. Basically drilled lots of holes all round the long bit.

I actually ended up having to grind down the butterfly slightly due to it not opening and closing because one side of my pipework is 2.5" and the other 3" but you can't actually boost with it closed anyway and if you give it too much throttle it will behave like its got fuel cut, (worth remembering when trying to get out of junction's quick;)) I don't think drilling will help with noise suppression ie defeat the object, as mine is only quiet when its pretty much fully closed.

Dash Rendar Posted September 29, 2007 Share Posted September 29, 2007 I have a Nur Spec R and I drive mine with the baffle for long journeys, and if I have to get up very early in the winter for many consecutive days. But at all other times, I take it out 'cause it sounds so nice! But you might be interested to know that I actually dyno'd my car with and without the baffle, as I was interested to see how much performance I actually lost. It turned out that I made 315RWHP (it's a BPU Auto) with the baffle out, but only 305RWHP with the baffle in, and a drop from 1.2 to 1.1 bar.
