Installed the exhaust a few days ago, took sound clips & will post pics tomorrow (hopefully I can figure out how to post the sound clips). I echo Deeprumbles' assessment regarding the fit, finish, and overall quality of the exhaust. The exhaust came packaged better than anything I've ever received (this may be the standard way to ship an exhaust since I've never bought one before, but still very impressed w/ the care in packaging). The flanges are very substantial and they mount up very true. No adjustment was necessary at all, everything centered up and the tips are the same distance from the bumper recesses as the stock tips.The welds are very good and the tips are solid, just a very nicely put together system. For $399 shipped I was expecting thinner walled tubing and not the perfect fit & quality finish that I ended up receiving. I wasn't expecting junk, but I just had lower expectations since the price was so low and there wasn't much history on this particular application.

I really like the deeper tone of the exhaust note, just a mellow rumble at idle and really opens up nicely as you get on the gas. It also passes the butt-dyno test, definitely feels more responsive. If anyone is on the fence w/ this exhaust I'd jump on this deal. Sure there are more complete "true" catbacks, this IS only from the Y pipe back, but it a lot of bang for the buck. Just about as much money as an intake, but you can enjoy the sound all the time

 

I'm in for the pics, blnewt! Congrats on the mod. Now that you've got it on your car, can you double-check the tip-width, please?

And don't get too hung up on that "true catback" nonsense. You bought some nice, new mufflers for a decent price... go with that.

 

Thanks! The tips are 4.5" OD so they definitely give the sedan a more aggressive look. I'll get those pics up this afternoon.

 

As promised, hopefully I'll get those sound clips up too

 

I don't know diddly about welding, but that looks like pretty thorough manufacturing and materials. I think tips are a little bit too wide (for my taste is all), although they do look good. Perhaps the reason they seem so prominent is because the slash cut is barely perceptible, like 10*. If it were a 30* cut, that might do the trick for me.

OAN, look at you with the vinyl overlays on your tails and the partially debadged trunk. Looking good in black on black.

 

Thanks, I'm very happy w/ the build quality and the tips cut looks about right from the sides IMO. The pipes are pretty big but fits well w/ the lowered stance, blacked out grill, lights, and trim. I think maybe they'd look overly aggressive on a stock G sedan however. I like the look of the overlays but I think I'll be painting the tails later on and also the headlights when I get brave enough to put something from my car into an oven, lol

 

Well, that's true. Overlays take a better picture than they actually look up close with your own eyeballs. It's always a personal call.

 

Actually I like them better in person, they don't seem to photo as well, at least that's been my experience. I like the result, but the painted headlight housings really stand out. I may just leave the tails as is, they look pretty sweet at night

 

Here's a couple sound clips, sorry for the crappy audio, it really doesn't pick up the idle tone much at all

looked like you got stuck for a minute there pulling into the driveway lol.

Can you get any sound clips from the interior, especially at normal driving speeds? Any drone?

 

LOL, it is a steep drive and I choked under the pressure of being filmed

I'll try to get a cabin sound clip for you in the next day or two. No drone that I can tell, just a deeper tone in the 2-3k range.

 

You gotta admit, that was kind of funny in a Warner Bros. sort of way.

It must certainly be nice to be able to hear your car again (I miss that). How's it sound inside at cruising speed? IMO, the idea exhaust would be deep and rasp-less with the throttle, but relatively quiet when cruising at low idle.

 

Not bad. Looks like my Tanabe, but sounds a little bit louder.

 

This really sounds good. i might look into these.

 

Here's the interior sound clip, sorry for all the background noise, not sure what the hell caused all that
