DIY Cherry Bomb conversion

[RWDKurt]

I've had a good read through most of the posts on fitting cherry bombs (or claiming to!), and wondered if anyone had sourced the bombs themselves for a local Indie to fit. If so, what size of bombs are needed to fit within or replace the standard silencer on an early 4 litre Chim?

Thanks in advance

Kurt

Hi - I'm up in the North East, close to Middlesbrough.

Thanks

Kurt

Thanks for that Mr Moneypit. Sheffield's a 4 hour round trip for me but still worth considering. Looks like a professional outfit.

Anyone been down the DIY route at all?

[RWDKurt]

OK - I'd be happy to source the parts from Richard in lieu of good advice - I'll give him call.

Cheers

why not get the sports exhaust from act then you can sell your old exhaust to off set the money .

You can get cherry bombs off e-bay- source them to fit in the lenght of your silencer box, with a 50mm opening. Open the box from the top by cutting along both sides, half way up then over the top at each end, remove the silencing wadding. cut perorated pipe so you can slide the bombs in place. Tack weld over perf pipe ends, replace the wadding to keep resonance down, weld box back together,(MIG WELD) and hey presto

Daz - I may go down the ACT route but at £460 plus VAT it's worth considering other options. I know my standard exhaust might be worth something, but not a great deal I'd guess!

Sapper - thanks for the info on Cherry Bomb pipe diameter and the rest of the DIY tips - much appreciated. Any idea on pipe length?

Cheers

Cant say 100% sure so its best to measure your silencer box. 400mm I think but honestly not sure. Whatever the length of you box give yourself a couple of inches to spare to allow for fitting inside... oooeerr missus

[RWDKurt]

Cheers Sapper. I'll get off my posterior and get under the car at some point to check...

where did you see the cherry bombs on e bay ?

[RWDKurt]

US Cherry Glasspack Exhaust Bomb 18" Body x 2" ID, available on ebay for £28-00 each plus £10 P&P (Partsorama). You'd need a pair of course, and we still need the confirm the required length, but for £70ish you'll have the bits you need. I'd guess a decent Indie will want around £100 to do the work, so for £170 you have a 'pukka' conversion.

It won't go any faster of course, but it'll sound faster...

Had thought about this too and found this:

Obviously i too am interrested in the appropriate size of the cherrybombs, so if anybody gets the answer, please post it up.

Cheers Jens

Hello Kurt if you post your question on the north east forum i am sure someone will pont you in the right direction to someone who can do a cherry bomb for you i am sure its been covered before and if i remember right there was a place in Lemington that was highly reccommended . Near the the big B&Q near the scotswood bridge i think . good luck and let us know how you get on . Tom .

thanks.am i right in thinking that cherry bombs give a deeper idle sound as apposed to having a straight through system ?

[RWDKurt]

dhf - I'm not sure you'll get a definitive answer to that question without having one of each to compare. If you do a search on cherry bombs, you'll find many people who think that's what they've got, but when they open up their silencer it's actually straight through (ie just 2 lengths of 2 inch pipe) hidden inside.

[dhf]

thats basically what i have at the moment and i want to change the idle and up to 2000rpm to a deeper sound as its a bit agricultural at the moment.any of the you tube clips i have heard proporting to have cherry bombs fitted do seem to have a deeper sound.Peninsula will be cutting the box up first week in october so will post results then

sounds familiar. There is always another option. mixing straight trough and perforated pipe. you dont get the crackle on over run but you do get a very deep gurgle and it can be pretty loud enough when you want to be without sounding nascar

Thats the route Peninsula want to go.will keep you informed and get the measurements.

ive just looked at my exhaust, i dont think you can weld them in side because the two pipes start wide then close together with in the silencer box. there are other options eather just weld two straight pipes in the silencer box as normal then fit eather one in line cherry bomb or get the other type with tails on the end and weld then at the end . im not sure if the tvr chimaera exhaust is s steal .are they two different types of steal .

[sapper]

Daz this is what it looks like inside whith straight through pipe sports exhaust
You can cut away the original pipes as required then just tack weld the cherry bombs in place as I did to put 50% perf pipe in place.
