LouisW Posted May 27, 2016 Share Posted May 27, 2016 Hi Everyone,I have recently acquired 2 cherry bomb exhausts and I am hoping to have them as a twin rear exit. However, I am hoping to recess them someway into the boot floor in order to get them to sit nicely at the rear and keep them away from the ground. Has anyone else had any success with doing this before? Had spoken to someone who had cut a 4" tube in half and welded those into the boot floor allowing the exhaust to sit higher. Some rubbish pictures of the exhaust. But hoping it looks good! Quote Link to comment Share on other sites More sharing options...
Velocita Rosso Posted May 27, 2016 Share Posted May 27, 2016 The main problem for lifting the exhaust is the rear cross memberYou can lift the boxes right to the boot floor but then you need a formed silencer going from the front of the diff, going down and then up again Quote Link to comment Share on other sites More sharing options...

LouisW Posted May 27, 2016 Author Share Posted May 27, 2016 Yeah, that's my problem, I know I have to form some sort of y joint but its difficult to get around the diff. Quote Link to comment Share on other sites More sharing options...
LouisW Posted May 27, 2016 Author Share Posted May 27, 2016 Quoted from stevegt6 Fuel tank might be an issue..? I'm not going to go anywhere near the fuel tank though, and my flooring will be heatshielded and carpeted. Exhaust wouldn't be touching the floor but very close to it.

LouisW Posted May 27, 2016 Author Share Posted May 27, 2016 It's going to have to be routed from behind the diff and round on either side like the picture below. I dont think it will be possible to have them angled massively upwards like in my mock up but I wasn't expecting to be able to really!

stevegt6 Posted May 27, 2016 Share Posted May 27, 2016 Was thinking more about room for a 'tunnel' type thing if you were shoving it up in the boot...Here's a pic of the twin pipes on mine - the the regular stainless sports system supplied by most - Don't have any issues with ground clearance unless really going some on an uneven road or an unseen small hump back bridge over a canal 😉 but just get few sparks and a little bit shaved off the metal Quote Link to comment Share on other sites More sharing options...
stevegt6 Posted May 27, 2016 Share Posted May 27, 2016 Hmmm......that pic is bigger than i thought it was going to be lol Quote Link to comment Share on other sites More sharing options...
stevegt6 Posted May 27, 2016 Share Posted May 27, 2016 They look pretty good - a bit less obvious than the big cans on mine.... Look forward to seeing the end result Quote Link to comment Share on other sites More sharing options...
RedRooster Posted May 27, 2016 Share Posted May 27, 2016 Had to cut & re-weld every bend on mine to get it to fit properly.Sorry , link no longer availableRR Quote Link to comment Share on other sites More sharing options...
LouisW Posted May 27, 2016 Author Share Posted May 27, 2016 I just have the standard exhaust all the way to the engine apart from the cherry bombs. I have no experience in bending steel tubing or welding steel tubing! How much am i looking at to take it to a custom place to get the y joint made?

RedRooster Posted May 27, 2016 Share Posted May 27, 2016 Just buy stainless wire / rods and give it a go, thats what i did. Quote Link to comment Share on other sites More sharing options...
BiTurbo228 Posted May 27, 2016 Share Posted May 27, 2016 What a brilliant idea I'll try that with mine when it comes around to it.Watching with interest. Quote Link to comment Share on other sites More sharing options...
GT6 M Posted May 27, 2016 Share Posted May 27, 2016 2 cherry bombs will be v v noiseyIt will be v v awfull after a while at speed.And, angling a cherry bomb upwards, then it,ll fill wid water. = rustjust me tuppence wuthM Quote Link to comment Share on other sites More sharing options...
LouisW Posted May 27, 2016 Author Share Posted May 27, 2016 I can buy 3m of mild steel tubing in 16 AWG, 1.75" diameter for £10. Shall I do this and just have a play? I can make my own y joint and cut and join with my welder? Quote Link to comment Share on other sites More sharing options...

Good point on the upwards exhaust filling with water though, I hadn't thought of that! Quote Link to comment Share on other sites More sharing options...
JohnD Posted May 27, 2016 Share Posted May 27, 2016 Remove the spare wheel well and the rear valence - plenty of room!John Quote Link to comment Share on other sites More sharing options...

Martins Stag Posted June 1, 2016 Share Posted June 1, 2016 If you do get them very close to the boot floor I would put some heat insulation inside the boot to make sure you don't get the spare to warm (and your other boot contents)?Martin Quote Link to comment Share on other sites More sharing options...
chunky63 Posted June 3, 2016 Share Posted June 3, 2016 What about a side exit....with the added bonus of heated seats too...https://www.youtube.com/watch?v=aQPRVei48Bg Quote Link to comment Share on other sites More sharing options...
BiTurbo228 Posted June 3, 2016 Share Posted June 3, 2016 Quoted from chunky63 What about a side exit....with the added bonus of heated seats too...https://www.youtube.com/watch?v=aQPRVei48Bg I have wondered whether a good way to package a side-exit exhaust would be to cut the sill along its length, flip it inside out to make a concave sill rather than a convex one and run it through that space.It's something I wanted to try on an XJS as a way of avoiding the convoluted route the exhaust takes above the rear suspension unit, but then people suddenly decided that XJS' were worth more than their weight in scrap and they've moved out of my price range...

Jonny-Jimbo Posted June 7, 2016 Share Posted June 7, 2016 Might weaken the sill doing that by a fair bit, having said that, the strength could be put back in with extra ribs and extra support between the inner sill and the floor. Quote Link to comment Share on other sites More sharing options...
BiTurbo228 Posted June 7, 2016 Share Posted June 7, 2016 Interesting, and good point. I'll definitely do a bit of strengthening if I ever need to use that technique Quote Link to comment Share on other sites More sharing options...
Jonny-Jimbo Posted June 8, 2016 Share Posted June 8, 2016 It's not totally impossible...(Note, this car has from memory a Honda S2000 VTEC engine in, which is why the exhaust is on the drivers side) Quote Link to comment Share on other sites More sharing options...
BiTurbo228 Posted June 8, 2016 Share Posted June 8, 2016 I saw that car at Lydden Hill last year and had a chat to the owner great chap who's been running Spitfires for ages in various Modsports categories.He's moved the whole front suspension assembly ~6" or so forwards to improve handling and allow the AP1 S2000 lump to fit under the stock bonnet.Bloody quick little machine Oh, he was impressed with Marcus'/my rear suspension setup when I explained it to him Quote Link to comment Share on other sites More sharing options...
