Hawaii Chat Thread

Since this is a chat thread....must say...thank you to Kamu for installing the new exhaust and the sways. Thanks for your time and care in making sure that everything went smoothly and as best as it could.

Just got to figure out how to resolve that slight issue with the flanges.....dammit. Wonder if it got warped from shipping or just wasnt welded on correctly. Anyone know of any good gaskets to fill in a slight gap?

Also...my gosh. The 3.7 engines have a much more prominent after accelerating hissing sound than the 3.5 versions did. Thought it was just me...but after going on you tube and checking other 3.7 versus 3.5 aftermarket exhausts...it looks like the 3.7 is just louder in that department.

Heh, You think thats bad? You dont want to hear what mine sounds like then. It hisses *all* the time. LTH ftw?

Thats another thing.....I cant tell if its the hissing of the exhaust or a leak. LOL. I know that there is a slight leak...got to find a better gasket to seal it...but...maybe most of it is from the exhaust. I think that the exhaust change just amplified that hissing sound.

How are the F.I.L.T.H. ?? Heard and read good reviews on them. Technically I got the same thing with GTM resonated TPs and a full cat back system mix of Sunline and Amuse. The sounds between the two are VERY different though.

I hear a G37 with a FI exhaust and that one is low and pretty loud too.

Its most likely not an exhaust leak. Exhaust leaks sound very different than our engine hiss, and are very prominent. I dont really now how to explain that sound other than you would know the difference had you heard it; you would think your engine was broken. Its just hiss, and as far as I know, no one really knows what causes it or why its so prominent. My guess? VVEL. Just about everything weird or quirky about our engines all seems to stem from that.

As for the headers, I like them. A few friends have complimented the sound of my just driving around in light loads crusing, and the sound at WOT under full load combined with the intake is freaking loud, but sounds good. Power wise, its about the same as TP's. The TP and LTH perform very similar with only a few HP/TQ in the LTH's favor. I would hazard a guess that once some way to tune valve lift duration and overlap, we will see more benefit from NA and more notably FI aplications.
