Wrapping exhaust y piece on a griff?

[alexcurtis]

Hi all

Sorry another question…

Exhaust wrap yes or no, I am looking to do it as my exhaust Y piece has lost its Cat in the rebuild and may have gone a lot louder? Not sure if this is correct but one solution is to wrap it to help reduce some of the noise… I am happy with some extra rumble it is a standard exhaust otherwise just don’t want it assault your ears if you’re driving for a few hours!!!

I am only going to wrap the Y section of exhaust not the manifolds / pre cats

So questions are

will it help reduce any noise down if it not that loud I will take it off, I don’t have any issues ( touch wood) with under bonnet temps
Will it damage ? rust or crack the Y section or manifolds (biggest concern)
If ok to wrap whose products are recommended, the section is not on the car so can do anything with it!

Thanks in advance

Wrapping it won't do anything to reduce the noise out of the exhaust (no cats and no silencers = 'F*ckmethat'sloud!!!') and won't do much (if anything) to reduce noise under the bonnet...

Hi it's only the y that has lost its cat the manifold pre cats are still there and the rest of the exhaust is standard, so not ripped out completely by a long chalk..... He says

I ran my old 4.6 with a wrapped standard decatted Y piece and it reduced the under bonnet temp.

Hi phazed did you wrap because of temps or noise was it much louder after you lost the cat? Cheers al

I wrapped for heat.

TBH, there may have been a drop in noise, it was a quieter car then my current chim, both running standard exhausts although the larger capacity of my 5.5 probably adds to the noise output!

It most definitely does impact the noise though. Maybe not the level but the tone is softened dramatically. Wrapping the manifolds and the Y piece makes for a softer, more refined set of notes.

Spot on thanks for replies will wrap my decat y section then also help engine temps in front of engine not been an issue before but will help with induction and cooling cheers al
