Steve P Posted February 21, 2020 Report Share Posted February 21, 2020 I wanted something that fitted properly along the chassis rails and up under the boot,i had the wheelbarrow exhaust for years and got fed up with ground clearance and noise. Mat has a great setup making bespoke systems including manifolds about 15 minutes from me. Not cheap though,i think i deserved a sponsorship sign on his touring car.

jiggawhat2k Posted February 22, 2020 Author Report Share Posted February 22, 2020 Off-topic but car delivered back to me with roll cage fitted! Looks lovely I think, got orange harnesses to go with it. Made by Caged Laser Engineering who have been brilliant. Reckon I can get the back seats back in too, with slightly restricted access for passengers 😂 Link to comment Share on other sites More sharing options...

Steve Ha yeah did think about going custom but want to do as many bits myself if possible, believe it or not this will be the first time I've fitted an exhaust!

I'm regularly 103dB when the limit is 105. But, I've measured the noise in the cabin, and it's 95dB at full chat. NOT to be tolerated for road trips! OK with my helmet on when racuing, but I wear ear defenders when road driving. Yeah 95dB is too much for normal driving, hoping it'll help when I put full interior back in plus more sound proofing (just for my own sanity) and will try the universal silencer route suggested by @yorkshire_spam. I'll end up with an exhaust made entirely of silencers... Link to comment Share on other sites More sharing options...

Dyeing the middles black today then test fit 🤞 Link to comment Share on other sites More sharing options...

Nice looks cool! You finished it?? More pics! Mx5 seats look great. Checked mgf seats and they fit even with cage, bit tight but all good! 😅 I had a red 1500,loved it but crashed it (ran out of talent in the rain, bit embarrassing)... Bought it back off insurance and moved parts from spit to herald and sold shell, gutted but a nice chap called chris is rebuilding it so at least it still lives. Pic pre and post crash...

jiggawhat2k Posted February 24, 2020 Author Report Share Posted February 24, 2020 Exhaust manifold and straight section arrived, looks decent enough and can't argue with the cost from James Paddock, significantly less than rimmer/moss. Just looking at it makes my ears hurt though, I'll be adding a silencer as suggested... Link to comment Share on other sites More sharing options...
jiggawhat2k Posted March 21, 2020 Author Report Share Posted March 21, 2020 Brief update! Wrapped the exhaust in some nasty exhaust heat wrap, looks good though. We then fitted the FH engine (out with the dead 1500) and the new exhaust manifold I bought from James Paddock as suggested by @yorkshire_spam. Also as suggested here, it didn't fit perfectly, tbh almost every mounting hole needed filing down. Got there in the end though and it looks great. Need a silencer as my straight section isn't quite long enough to reach the back. Londlg day but went well, needs timing, exhaust and a new brake booster (air keeps getting into brakes, can't fully bleed them).

jiggawhat2k Posted March 28, 2020 Author Report Share Posted March 28, 2020 Bodged together the exhaust finally, skinned my knuckles due to not much space to work but went well. My first ever exhaust so I'm pleased. Is made up of the 421 James Paddock manifold (2"), to a jetex 2" silencer, then flex join to 2" straight pipe, then another flex join and cherrybomb. No idea what it'll sound like, I suspect loud... Also used a couple of old polybushes as the rubber mounts, let's see if they're effective... Note any missing/loose nuts visible in pics have been fixed, also now added additional nuts to lock any non-locking bolts. Sticks out a bit at the back a little so need to be careful when parking, probably 1 flex join too many but the car is low and I needed the extra flex join to move the cherrybomb off the floor. Phase 2 will tidy that up a bit, when I get a chance. Cheers all for the recommendations, all plugged together as you described! Above is the one with the polybush between the chassis and hanger. 2 Link to comment Share on other sites More sharing options...
AndyTV8 Posted March 29, 2020 Report Share Posted March 29, 2020 Nice job... fingers-crossed the sound will be to your liking..... my first car was a 13/60 with twin SU’s and 4-branch manifold, I used the TriumphTune wheelbarrow handle twin silencer system, I loved it but it did fail the MOT on excessive noise! A chat with Mr Hurrell and I replaced with the silencers with ‘acoustic tailpipes’ essentially some extra baffling. have fun .......

Sounds good fun. Glad I don't need an mot! Like the idea of twin pipes, they look smart. Link to comment Share on other sites More sharing options...
yorkshire_spam Posted March 30, 2020 Report Share Posted March 30, 2020 Looks like you made a nice job of fitting the pipes and hangers - it looks nice and professional! I'm on the wheel barrow style as well, although mine are on the Spitfire 1 Link to comment Share on other sites More sharing options...

jiggawhat2k Posted April 4, 2020 Author Report Share Posted April 4, 2020 Minor update, got the car running on the engine we just put in last week, did some of the carb tuning but still needs work (mix isn't right and idle too slow). Still, the exhaust sounds really great, excited to drive it hopefully for the weekly shop next weekend. Am tuning it with an airflow meter plus I have a gunsen colortune which I love using, what a cool tool! 20200404_172423.mp4 Link to comment Share on other sites More sharing options...
jiggawhat2k Posted April 25, 2020 Author Report Share Posted April 25, 2020 Checked the dB of the exhaust I fitted, 88db! No idea what my neighbours complained about lol. Let's not question the validity of the app for now... Link to comment Share on other sites More sharing options...
