You need to take the font / over pipe all the way loose from everything else when you tighten down the front flange, that is about the only way to prevent leaks unless you add some high temp sealant like ultra copper, and don't over tighten as that can cause leaks.

Just about every aftermarket exhaust setup will produce some leaks without some finesse and re-positioning. It's nbd and can generally be solved with higher quality gaskets than what are included with the product.

I will tighten the over pipe to header first this time, before the header to block. I'm hesitant to disconnect the front pipe from the mid pipe though.

I do have the front pipe loose from the transmission.

Is there a correct torque sequence for the header to block nuts?

I went inside inside front front rear rear.

Do you suggest to buy grimmspeed gasket set?

I have: Nameless Header / Nameless DP combo 2,5" / Perrin Resonated 3" catback.

Should I get the full gasket set plus the DP> 3" Catback gasket in addition or it shouldn't be needed? I live in Italy so I can't like you guys get a new gasket very easily in case it start leaking.

I'd get full set + 3". The nameless adapter is a little flexible. Better safe than sorry

It is very mild mannered at cruise, but gets loud in a hurry when you get in it. I love it. Slight drone at 3800-4200 rpm but I'm never there for more than a very brief moment. Cruising rpm is well below that.

Interesting - that IS Italian sounding.

You must have the craziest oven mitts...

I haven't checked the one i put on yet, but i had a difficult time tightening that last nut near the overpipe flange.. I torqued it to 40 ft lbs using the grimspeed gasket..

with the stock exhaust and nameless overpipe resonated it certainly was loud.. almost raspy.. again, I'll need to smoke test the exhaust for any leaks before I can determine if there is any leaks..

also, not sure if it was mentioned here already, but if you have the OEM intake tube/airbox be sure to remove the tube before installing.. the resonator on the intake tube interferes with the header, you use the cap to block it off..

Quick tip if you don't want to jack up the engine, just remover the oil dip stick and they will fit into place.

Been running the header untunned with the spacer, still managed to get a check engine light.

I hope nameless send instruction about how to fit it and what resonator to remove etc. etc.

I just pushed with moderate pressure, it squeezed through.

Quick question for all you guys who also have it installed. How exactly are you determining the presence of exhaust leaks at the head to header connection?

I, like many of you, installed, tightened to factory spec, and got that really loud ticking/blowing sound on startup. I re-tightened to 31ft/lbs (still less than a lot of people are tightening to) and the noise happened again but then went away after the initial warm up cycle. I have since started it cold several times and have yet to hear a re-occurrence. Now I'm a bit paranoid because yesterday, I found a leak between the header and overpipe that only presented itself when I revved the engine.
