Driving With Silencer In Exhaust

[taynewguy]

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.

i guess that depends on the type of tune your have.

your car would certianly be alot slower but if your not gonna be boosting it much it should be fine.

i found when restricting my exhaust my fuel economy went real crap.

I wouldn't drive it hard with the silencer in, no high rpm stuff. If you worried get it on the dyno with the silencer on for peace of mind

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

make sure u fix it in tightly... i tried that once, gave it some gas to see the different in performance and the part shot out down the street.

Yeah I know what you mean - it is a big restriction which is held on by 1 small bolt.

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 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!!
