Dump Pipe And Quick Spool?

[(B1) MR_fanny]

gday guys and gals

installed a batmbl dump pipe + hi flow turbo. great products!! got it installed yesterday but they left the heat shield off because i assumed they couldnt bolt it back on due to the tight fit. modified the heat shield today with the good old angle grinder to make it fit using just one exhaust bolt thats easily accesible. durring the process took the other 2 bolts out to test fit. now i can hear the turbo spool very early, below 2k even before induction noise starts. is this normal or do i have an exhaust leak? bolts not tight enough?? they are pretty tight but i dont want to over tighten them incase i snap them which ive been doing lately...lol

you probably don't have a leak. But if you do you will be able to smell the leak at idle in the driveway when you check under the bonnet or under the car.

I know.. its a VERY VERY tight fit indeed..

Esp that stupid aircon pipe in the way of the wastegate pipe.

would have been better if the wastegate pipe came over a little more to the left n up, and the 02 sensor down the bottom..

But anyways think i hear early spoolin sounds as well..

But otherwise quailty is excellent. you can deff feel the incresae in power.. love it..

but now cravin for more power..

You would be supprised inthe increse in low spool now and i have stainless

one and from under the car you can hear it pulsing in the pipe ,so

it wount be a leak and you would definatly hear in the bay.

so all is good , just check them in a week o so

as they man need to be retorqued.

Yeah I've noticed with stainless dumps vs cast you can hear the turbo starting to spool for sure. This is when I've swapped stock exhausts to aftermarket and vice versa.

thanks guys.. ill check it in a week to re tighten em up.

car drives silky smooth now throughout the rev range. its fantastic!!. does anyone think the direct contact with waistgate pipe and the air con pipe will cause any long term problems?? i was thinking of modifiy the aircon pipe mount to move it over a tad.

[siddr20]

Yes it will, even tho the aircon pipe has heat wrappin around it already!!

Sine it sits like a mm off, during summer it will melt that wrapping for sure.. IM gonna reallocate that pipe soon.

I would wrap it up just incase, coz you never know. Just imagine the temps down there on hot days.
