Diy'ed your DPs?....tell of yr experience

I've had DPs now for nearly a year and constantly toy with the idea of fitting them myself vs getting them installed. How hard can it be right?...basically unbolt stuff then bolt back up?!...only difficulty being space or the lack of it?! Anyway thats how i perceive it but i could be wrong. Let me know of your experiences if you have done this and/or know of people who have. Any pointers, issues, things to be extra careful of etc. would be greatly appreciated.

I will be hiring a ramp so getting the car in the air will not be an issue.

As you've stated Shaun should be bolt off bolt on, thing is these pipes vary in quality we did Josh's last earlier on and they fought us all the way through just simply didn't fit right at all their diameter was slightly narrower than mine yet mine went in with little alteration to heat shields.

I guess the issue we saw was Josh's pipe's looked like they weren't quite the same in terms of end quality as say some others we've seen and we've done around 10-12 sets and this was by far the worst one pipe wise we've seen. In the end I had one guy underneath and one guy at the top both working at the same time making tiny adjustments to get everything to fit right ensuring no bolts fowled the pipes and when fully warmed up there were no issues we test drove the car too to ensure side to side movement when corning didn't get the pipes fowling and everything on Josh's car was perfect despite the pipes despite the pipes not being the best one's we'd seen.

The other thing you've got to look out for is potential damage to the o2 sensors as they are delicate at at 160 odd plus VAT you damage one of these all the work you'll be doing your self will be undone as this will cause the work to be halted or you'll get the pipes on and then have to go back and gain access to the offending sensor remove it replace it which could again due to space take a good 2-3 hours of your time.

If everything goes according to plan you'll be spending a good 4-5 hours under there.

IMO its not beyond anyone with basic spanner knowledge to carry this out, but you'll curse if you have an issue re a sensor(s) and expect some heat shield cutting here and there too as they do contact the heat shields in places due to the angle they exit.

But good luck expect tied aching arms...

Depends on make as to how good the fitment is. Did mine myself (ar design) did it on Axel stands and was tight watch o2 sensor on steering column other than that just a little tight Oh also check posistion of the v bands make sure when u replace them you don't block actuator arms other than that for a first timer allow 3 to 4 hours.

To add to that if you get a spanner for the o2 sensors and cut it in half you will find access to them a lot easier.

Any recommendations on the penetrating fluid?

Also approx what length did u cut the spanner to for easier access to the o2 sensors? Do u remember the spanner size?

Spanner 22mm can't find tape measure garage is a mess! It's this long now



It could be a bit longer or shorter as long as you can get a good grip on it but I couldn't find a spanner 22mm that was short so just got a cheap one and cut it in 1/2

You could of course buy a proper 22mm o2 socket and swivel head the cut spanner was easier for me but a guess on torque!!!

Check your pm too I have pm'd an install vid link it's left hand drive but exactly the same other than we have steering column in the way I watched that vid before I did mine and found it very helpful.


Good luck you will really enjoy the extra power. I hope you have Cobb or jb4 to deal with the check engine light the missing cats will throw up.

As already said by myself and Steve be very careful with o2 sensors even knocking them about on removal or install can break them

I've changed several sets on 135's, the Wagner V2 pipes are the best fitting so far.

The job itself is a ballache. Get the right tools - O2 sensor socket, stubby ratchet for the v-band bolts - and its not too bad if you don't snap any of the studs off the DP to Midpipe connections.

Personally I would also replace the V-Bands while you are changing the DP's.

Shaun as you know we did Josh's pipes a week or so ago(and water pump and thermostat)




forgot I had the photo's as I'd usully do visters thread but due to being b****d I didn't get on it.

Josh had VRSF pipes and TBH its the only set as I'd stated elswhere that really fought us. Nothing on these pipes lined up




The above pictures showed the first install finish once bolts had been tightend up as you can see the gap wasn't ideal. As you know the pipes when fitted swing away then curve back in towarss the centre of the car as illistrated below(pic showing shows the pipes laying in situ post first fitting)



and the offending bolt



the issue we had with Josh's pipes were the fact that when tightened they pulled over a little too much and sat right on the bolt circled



The only option we had was to be "creative re what we saw"to try and resolve the issue. This is the first set we'd encounterd that created an issue. Never seen them sit bolted up like this the only thing I can say is that they'd somehow judging by the gap on the exhaust and the fact that they didn't sit right were not manufactured quite right.

In the end they were losned off at the top and bottom and I had 2 guys one 8 ft in the air on a 4 poster adjusting the pipes from the top and one under neath doing the same tweeking here and there, as with most of the cars a bit of heatshiled was lost, modified where required as on the off side thre was touching evident but in the end we got no gaps pipes that fitted don't touch anything and don't resonate.

As stated above its a ballache is DIYable but be prepared for the unexpected

My very very good and competent local mechanic literally shed blood and sweat installing my AR design catted down pipes. Not a job I would want to try on my driveway. But if you manage it top man I'm far too incompetent to even think about trying something like that..
