stevef182 0 Posted August 21, 2008 yeah i guess, having asked so many people about it i had kinda realised i would just have to deal with it and as you said hope it goes away! cant see it happening though! oh well Well like i say mate, mines alot quieter then it was when i first had it fitted, so there's still hope ;) How many miles have you covered since fitting it, what manifold is it? i havent fitted a manifold, my car had a miltek exhaust which was so nice and sounded soo nice, but the cat rattled really badly so following the suggestion of the garage i use i had a de-cat pipe fitted and it has made the noise ever since! :( Quote Share this post Link to post Share on other sites

It should still quieten down. Quote Share this post Link to post Share on other sites

joeyboswell 0 Posted April 25, 2010 This is about the most similar to my problem at the minute except I have just had a Jetex cat-back exhaust fitted and obviously kept the cat. It is only at certain points through the rev-scale but it sounds like an empty aerosol as described here. I'm hoping it is just the heatshield on the exhaust or the under-shield on the cat. If not what could it be? Could it be something to do with the new exhaust? I mean the actual exhaust and air running through it's pipes or does this only apply to maifolds and de-cats?

Critical_Mass 10 Posted April 25, 2010 I suppose it could happen with an exhaust too, but not sure tbh. By the way Heatwrap quietens the manifold noise down. :D sorry not much help to you Joey. Quote Share this post Link to post Share on other sites
joeyboswell 0 Posted April 30, 2010 Turns out my noise was the cat heat shield being loose and a washer missing on the rear heat shield. All sorted now. Quote Share this post Link to post Share on other sites
