Hey guys/girls,

This my be a stupid qustion but can i potentially do any damage to my car if I drive with the silencer in the exhaust?

The car is tuned at 381rwhp @ 18psi and I'm running a Blitz Nur SpecR exhaust which is pretty loud.

Running poncams also which makes it a bit lumpy and even louder again - pretty much instant yellow sticker job if I pull up next to a cop car.

So although it drives like an excel with the silencer in, if I am just putting around not driving at all fast can anything go wrong?

Obviously i would take it out when wanting to drive it hard, but I'm just concerned I might damage something by restricting the flow so much.

Cheers,

Tay

I remeber a magazine article were they were testing a high flow cat, car had been tuned for the high flow cat, so they decided to see the diff the original cat made.

Stock cat ended up being a massive restriction causing detonation etc(high rpm end). so I see your new silencer as causing similar effects IMHO.

Ok cool, thanks for the heads up guys. I just put it on yesterday to see how much it would quieten it down and went for a sunday drive.

Didn't really give it a hard time but didn't see any excessive knocking either way.

Found out pretty quickly that it's no fun, deadly slow and with absolutely no accelleration.

Anyway, that drive didn't last long. Quickly went home ripped it off and went for a real blast up in the hills.

All smiles again :banana:

I got one of those.. keep it in the boot actually, it's got me off a yellow sticker before for my exhaust being too loud :laugh: I just said it'd loosened and come out and I needed a screwdriver to get it back in ;)

Driving with it thou is boring, and sounds like crap!!

    • I hope it's actually possible. This is a write off in insurance world.
    • Yup. 2-way with shallow ramp angles. Still works.
    • That was the first session so not a lot to take from the day. It was low 20s ambient and the coolant had got to 110 (and obviously had some pressure!) so that still needs to be addressed. I haven't downloaded the data yet but will. I had refilled the auto trans with Redline DT6 because it claimed the best viscosity I could find at 100o. It wasn't really long enough to get a good feel for that; while the trans got to 100o in the session it still wasn't shifting crisply as I hoped. I think I'll try a few more sessions before judging. No steering motor overheat but I'd hope not in only 1 session! But finally the suspension; it was night and day over the standard stuff and the car was a couple of seconds quicker on the same crappy tyres, which is a huge difference. I'll stick with that and get some sway bars and a mechanical diff sorted too and see how that all goes together
    • I guess it’s partially a compromise of how my car is used, wanting to be able to switch from drift to grip with track side on-car adjustment. Also partially with the way the knuckles are set there is more static camber but less dynamic camber gain. 
    • OK, so update from the track day on Friday It was a classic "an unfortunate series of events'. There were a few cars around and when i checked my mirror coming out of the fish hook I notice some smoke from the rear of mine. Looked again and it was getting much worse, I figured I'd blown a turbo or something to got off it and pulled off the racing line. However.... since it is a left hairpin into a right kink, I was on the inside of the next corner. There was a car passing me on the left and a big drop off over the ripple strip on the right......and someone had knocked the witch's hat that was on the apex about 1m onto the track. So, between those 3, I decided to mow down the cone and not damage my car/the other car. Right choice, but surprising result.  The car decided the cone was a small pedestrian so it blew the rear bonnet hinges up to protect their head in the upcoming person to car impact....I didn't see that coming and like an airbag deployment it happened super fast. Straight into the pits from there, everything was driving fine but it became clear it was a coolant leak not smoke, it was billowing up onto the windscreen. Onto the trailer and home. I'll do a separate thread about the repair (once I work out what it is ), but the immediate problem was the bonnet wouldn't open because the front was pinched onto the front bar and would not release. Ultimately we unbolted the hinge from the bonnet, pulled it back a little and it released from the front OK. "There's your problem", the top radiator hose had popped off at the radiator.
