Jimny Exhaust

I got a towbar installed on my 2015 SN413 Jimny and the fitters did not leave  enough room between the muffler and towbar so i get a constant rattle when turning. It has really been getting on my nerves so am just going to get an exhaust place to move the muffler to fix the rattle.

They also qouted me an aftermarket extractor and a new CAT system, does anyone have any experience with upgrading their exhaust system and whether it is worth it?

I saw this guy lost power from his exhaust upgrade  www.jimny-crew.com/exhaust-upgrade-dyno-results.html

Thanks 

Hi,
The space is a little tight for the rear silencer if you have a tow bar fitted, so its very sensitive to alignment.
By that I mean you need to make sure the mounting tabs are adjusted (bent) on the exhaust to get it to sit perfectly on the rubbers and level, if not it rattles. Even then over time the rubber mounts can stretch and again it can rattle.

I had need to adjust mine myself after the local exhaust fitters had put it on, useless bunch. Its easy enough to do but you do need to remove the rear bumper to get a better view.

Can't see much point in upgrading the exhaust myself, nothing wrong with the one it comes with. However, I do plan to get a custom-made rear box when mine rusts out so that its smaller and occupies less space, so less chance of it hitting the towbar steelwork.
Its not that expensive in the UK to do this, and mass produced aftermarket exhaust tend to hit the tow bar unless they are adjusted correctly, it’s a vicious circle!

My after market center section made my backbox rattle the towbar so I just bought a figure 8 exhaust rubber and used a couple of stainless steel zip ties to pull it away. Been working fine for a couple of years and not difficult or expensive to replace.

Stainless Steel ZipTies?! I didn't know they were available?! Just had a Google... that's definately a worthy addition to any 4x4's toolbox in the vehicle... I'll order some of them!

You are welcome.

The standard Jimny exhaust is very restrictive..... When my car was converted, initially it just had the back box removed and the pipe cut just above the axle. Whilst being noisey, I could notice a little more torque and a bit less movement up and down the box when driving.

I went to Tony Banks (Longlife) Exhausts in Leeds, he fitted a Redback Headers 4-2-1 manifold that I got from Ausralia and he built a full stainless 2" single box system with a 200cpa sports cat. The manifold was £230 and the system £600, madly expensive for a small improvement but something I do on any car that I keep for a while.

     

On the 1300VVT the results were good, much more drivable, more torque, fewer gear changes....... Probably a bit too raspy for a mature driver but you can go back to Tony Banks and he will alter the sound FOC if you are unhappy, I didn't.

On the 1600VVT the sound has deepend a little and drivability is great. Pulls cleanly from 1500rpm/25mph in 5th if you are gentle, is happy to roll along at 20mph in 4th and picks up fine. Hills have very little impact..... Still a bit too noisey for a mature driver but at 54 I'm unlikely to mature soon..... I drive gently around town to avoid too many stares.... but if I pass you on a full chat 3rd gear overtake on a B road, you'll look.....

The emissions tests were fine at MOT, I told the tester to get it hot as I was instucted to, when asked, he forgot and just tested it and it passed...

A worthy modification in my book but others will look and think it's crazy at those prices....
