Question Actually clean out exhaust - any benefits, or no?

FLAME SUIT ON - CHECK! LOL

Guys, I've searched and only one dude asked about the actual process of TAKING your exhaust system back off the car to clean it out - the rest are asking about the tips and crap...

So....

Since my tips get dirty (sute and crap) and seem to "sound" a TINY bit better when I clean out the tips really well - I was wondering to myself, would you re-gain a tiny bit of power and more importantly SOUND, if you dis-assembled your entire cat/back system and cleaned it out well...

Chime in please guys...let me know your thoughts..

Thanks!

doubtful - but even if there was minuscule benefit, it wouldn't be worth the hassle to do it (imo)... and it would be right back to filth in no time.

Wouldn't be worth it, but nobody's stopping you.

If anything I think you'd be better off seafoaming or something.

Well, I would imagine that the sute has to just keep building up and up over time (layers and layers). I can tell the difference (in sound, not performance) in the several years since installing my cat-back. I'm going to try it - screw it!

I'll let y'all know...

Thanks Guys!

there's a lot of velocity in the exhaust - not much is sticking... it's doesn't actually cake up to the point of impeding flow or anything... thats why I said it would be minuscule (if any) difference in performance or sound - and it wouldn't take long to be right back where it was before you cleaned...

But people have done more worthless things/mods to the G - so go for it, who knows maybe you'll post the next "Thing to do"... take a look at some of the other recent threads - people will follow just about anything someone says works <<< that's not meant to discourage your test though ...

I've pulled off exhausts that are 15+ years old. There is a layer of soot, but it's mere thousandths of a inch thick. A significant thickness is not going to build up in the system.

Ok, I value the .02's here...I'll leave it as is....just doesn't sound like it did when I first put it on...and it sounded the same for say four years...and now it just doesn't have that "Growl" that it did....heck.....it's something as simple as me getting used to it over the previous OEM exhaust...

Probably 100% true about cleaning it and it only taking a couple trips to work for it to be right back to where it was....

Ok, thanks guys!

I have 2 exhausts sitting in my garage right now...

One off a g35, another off an evo. Both are pure black inside, and there's no way in hell i'm spending any time cleaning that.
