DP install

[spunant]

Has anyone here done a DYI install of DPs on there 135 ?
I've found all the install videos for the left hand drive vehicles and its seems straight forward but our cars look a lot more difficult with the steering in the way.
Anyone done this themselves and have any tips or is it not recommended for the DIY home mechanic?

I recon this is not a DIY task, just have it done and save yourself a lot of and and

My friend and I did it on my car, he is very mechanically minded and I just helped. We used a hoist and It was still a total pain in the ass. It took us a good 6-7hrs and allot of fiddling. He said never again.

I watched my workshop do the install on a hoist and I even helped him out when he needed an extra set of hands. I recommend letting someone else deal with that misery of a job. So glad I didn't attempt to do it myself.

Not that I've done it but anyone care to explain which part is the hard/fiddly part? I need to get to the actuator arms...

Thinking this is probably best left to the experts, can anyone recommend a mechanic on the Gold Coast or Brisbane?

Accelerate Automotive in Coopers Plains did my install. They've done a few since then and are very familiar with the process. Speak to Alan or Karl and mention the forum and that you've been recommended to go there and they'll give you a reasonable price.

Prestige and BPS are also good options.

Thanks guys, I'll try them.

Just had my DP's installed at Accelerate Automotive, very happy with their work, I'd recommend them.
I was expecting a noticeable change in exhaust note but its not that much different, just a nice little rumble when down shifting
I guess that's good, doesn't draw too much unwanted attention.
Although I'm now thinking a sports muffler, something a bit lighter than the oem one. Again don't want it too loud for obvious reasons.

Glad to hear it all went well mate

Reviving a semi-old thread as I have been reading through the entire history of 1addicts ausforum :P - This thread brought back memories of me DIYing my DP on my s15.

Worst idea to start doing this at midnight on a friday... ended up rounding off the bolts on the stock dp. Had issues with fitment, lining up with the front pipes, high flow cat, catback... +4-5 hrs later with the sun rising, finally installed!

But god was it worth it! The difference the 3" down pipes/front pipes does in terms of rwkw and acceleration response was significant and arguably comparable to a tune from my experience!

A bit off-topic, but has anyone here installed catless DP on a N55?

If so, how have you found the smell/noise and does it draw the "wrong" kind of attention?

IMO I don't think the smell is that bad.. it's there sometimes but obviously dont let the car warm up with the garage door closed. As for noise, with the stock exhaust it's not too bad, can get loud especially with a cold start. I'd always recommend the high flow catted though.

I did it myself using the AR Design DIY video. Give it a look on YouTube. It's the best one out there.

[BMWRX]

Spunant, how was the difference in acceleration/power? Did you notice much of a change in cabin noise (i.e. Turbo whine, etc)?

You're in the Aussie forum. As we have RHD vehicles we get the pleasure of having a steering rack in the way so unfortunately for us, it's twice as hard as LHD vehicles for DP DIYs. I wouldn't mind DIYing if it wasn't for that. It's still doable, I've just heard that it's a massive bitch to do.

I know the N54 is way harder to install downpipes over the N55. Still had it professionally done.
