That should = 'zero back pressure' = instant spool up?
How come us hill climbers have to be under 110 dB or we don't race and you can run open header?
My 911 on open pipes clocks 108 dB
911

 

Use a small head cold chisel with a decent hammer, it will come off easy..

I did my 93ra rally car in a few hours...If you then clean up the residue with a cloth and white spirit, it will come up like new..

I put all of the removed sound deadening in a carrier bag and weighed it..
couldnt believe the result!! nearly 10kg

good luck

this just keeps getting beter and better

i know it will be load but we dont have to go through a noise test

we ran a 3" pipe striat through on the vectra

there is a sierra with a 4.8 v8 from a range rover up there with just the manifolds sicking out of his bonnet

JESUS THATS LOUD

no need that loud

IF ALL THAT DEDENING WEIGHS 10 KG THATS 22 POUND

LOOKS LIKE IT WILL HAVE TO COME OUT

 

Sounds like a great project but beware of the weak rear diff if running RWD! I run a Rover200 RWD rally car, 240Bhp N/A VX XE engine, broke the R160 4.44:1 LSD diff several times and also a couple of shafts have sheared off. Suggest you at least upgrade to a R180 and associated uprights & shafts for RWD use. Otherwise graft in a 9" Cossy diff! (like I did in the end on the Rover)
