Stack Exhaust

Hi All,

Was just wondering whats involved in fitting a stack exhaust to my HCPU and if i need to declare it to insurance and would it pass an MOT?

Cheers Robert

As long as it's not possible for a pedestrian to get burnt by it and it int too loud (fink that's a plod problem not mot though?? just cut hole in floor of pick up and run straight up back of cab.. Don't forget a hinged flap on the top..

I was thinking along the lines of this...plus generically diesils run colder than petrol engines therefore by the time it reached the stack it wouldnt be that hot

Dont need one with a muffler in it just use a straight tratter pipe, I got mine from the local Case shop, gonna turn them into twin underside side exits on the disco later this year

so its legal then...did you have to notify anyone?

no, not really if you want to cover your back just tell the insurance company you've fitted a non standard exhaust but stress that its not a performance part

I wasn't going to bother telling them……it doesnt affect the performance its just looks and noise

wonder if the DVLA could shed some light on it

Just do it……….

How did you "plumb" your stack in, i was thinking of buying a straight mid box replacement pipe and cut a bit off it and use exhaust flexi

off headers to the y pipe, onto 2.5" bore straight pipe, onto stack…….job done

Didn't Bucky have a stack pipe in his 90? May be wrong but think I saw piccys in another thread?

Bucky's stack is actually his air intake and not an exhaust.

I'm doing a stack for mine using the parts for the side exit set up, search for Trewey's fred on side exhaust, it lists all parts needed, you just need to replace the end cap with a stack going up. I think Trewey used a muffler as well ( links on the thread, the muffler sits inside the wheel arch ) but i'm thinking of not bothering.

i would like a twin stack with one being the air intake and one the exhaust but not sure i can get matching end caps that serve both purposes.

I've got a pair of matching truck stacks if interested, save me from making underslung twin side exits and take them off me haha
