    Rated 5 out of 5 by from Quieten straight through exhaust A few years ago I foolishly thought it would be brilliant to have my exhaust's standard backbox/rear silencer removed. It was replaced with just stainless pipe. The glorious sound of six cylinders snarling at my mates was really good fun at first. But now the novelty has worn off somewhat. I still wanted it to be fairly free flowing, but quieter and most importantly - cheap! So I splodged a load of this inside my tail pipes. Far enough in so as not to be seen. At first I didn't think it had worked, but after a drive it expanded with the heat and has noticeably taken some of the harshness out of it's sound. It's still loud, just a bit more bearable now. It obviously restricts things a bit. Just be sensible and don't bung your exhaust completely. By no means is this as good as a proper silencer - but for 4 quid try it!! You could always scrape it out if it doesn't work for you. I'm a lot happier anyway. And maybe my neighbours might be grateful too.

    Rated 5 out of 5 by from Excellent. Stuff Took a few minutes to find leak by switching engine on and spraying exhaust with soapy water (it bubbles where it leaks ) another 5 minutes putting gum on after exhausts cooled down left it overnight and next day no noise brilliant !!

    Rated 5 out of 5 by from Simple yet effective. This putty has blown me away, the quality of the product totally outweighs the cost. I recently bought a 2nd hand moped as my first vehicle at 16. From the start it was abnormally loud but i just threw it aside as a noisy moped. Over time it got louder and louder and upon inspection i found a fingernail sized hole. I considered my options and thought of giving this putty a go. I was first pleased with the quantity of product given. A lot to allow for big and tight seals and multiple tries. 2nd i was pleased with the drying speed. It dried upon my fingers with a fiberous feeling. Obviously this allows for a strong seal on the exhaust. The sound difference even when drying was amazing. I yet wait to listen to the final product and cannot give my opinion on the durability of the product having only applied it today. So far i am super happy with the product. P.s. Halfords, please send me products to review.

    Rated 5 out of 5 by from Brilliant for temporary fix Helped me out of a very noisy situation. I combined this product with the holts exhaust bandage on a part of my exhaust and it done a good job but the exhaust did eventually need replacing. But it's good to sort a job out until the exhaust needs changing. Would definitely recommend to anyone who wants to save some cash.

    Rated 5 out of 5 by from Great stuff Bought the fire gum before this but that didn't last 5 minutes tried this as its lasted so much longer on the flange as one part of the flang was nearly missing after only being fitted 18months prior so great stuff and much cheaper than a back box for the time being.
