My exhaust shop did this as well. Cut the flange off and did a solid 2.25” from the resonator. I haven’t had to remove it so I cant comment of serviceability once it’s all solid

I bet it would make removing the pipe a little more difficult, or even impossible if it's welded, but it can always be cut again and rewelded if need be.

The exhaust shop i went to also welded everything solid. Personally I'm not a fan. The gaskets with spring bolts add a section where it can flex under stress. This is one of the reasons my muffler weld snapped after 3 years when I was at the track.
I also like to be able to remove the exhaust in pieces if I need to service anything. I hate not being able to do thatvwithba solid one piece exhaust.

I am currently welded solid as a repair was done which unbeknownst to me involved cutting out the flange. I hate the solid setup. I had been in the habit of swapping in my Tanabe Medalion for the summers, but no longer can. Now it just hangs useless in my basement. Your hands just become tied once welded in.

Exhaust Straight Talk...
Well, looking for opinions. Here is my current setup: Eastern Catalytics Midpipe which is large diameter until the resonator, then narrows down. This currently attached to the OEM Yaris, very restrictive, muffler. Question to you all: If I just bolt the Megan racing to the Eastern Catalytic midpipe, will it provide good enough flow. If I am only going to gain an almost imperceptible amount of power, does it really make sense to replace from the resonator back with large diameter pipe? I mean if I'm not going to feel a difference, is it really worth it. Maybe it would make a big difference. I also don't want cause the engine problems - in the long term - with too much backpressure. I suppose I could do this and then down the road, upsize that section of pipe. Thought and opinions appreciated.

I honestly wouldn’t mess with it yet. You’re still using a stock exhaust manifold so that pipe diameter reduction after the resonator likely isn’t your biggest issue.
I’d say just bolt it all up and drive it for a while. Try to sell off your 1nz parts and recoup some money, then revisit this in the future. |

I'm in. Domestic post in the us is pretty cheap, so I'm good with one person distributing them instead of separates shipping from the UK.

Yes, I was thinking that too. I suppose the true benefit of a freer flowing system comes into play when the engine is outputting at higher RPM. Thanks.

Exhaust Pipe Sizing
Thought I'd do a little reading about proper sizing for exhaust. For now I am just going to leave the 1.75" midpipe (from the resonator to muffler flange) and bolt up the Megan axleback. However, at some point down the road, I'll likely do an upgrade on that section of the midpipe. Here is a table for reference. I am not sure how accurate this is, but it talks about flow through a "straight" section of pipe. According to the table (based upon a HP output of ~130), I should use a 2" pipe. I think The Barber said he had great success with a 2" resonator to muffler flange upgrade. Considering that I have the 1.8L engine and there are bends, turns etc in the pipe, I would upsize to 2.25", which jives completely with what everyone here is saying.

Hate to break up the good exhaust piping progress happening but I just saw this and had to acknowledge its excellence lol.

As per PM, I had them sent to me, Sam. Not sure when they'll arrive, but I'll let you guys know approximately when to expect them. Thanks!

Like that do ya? Clearly, I have too much time on my hands. If I still had Photoshop, it would have been a better job. But Paint will do in a pinch.
