Anybody try or have this axle back from ebay?http://pages.ebay.com/motors/link/?nav=item.view&id=191093587946&alt=web
Seems cheap just wondering if its garbage. Says beluga racing on it. Just looking for a little noise from an axle back as the sedan is so quiet. Trying to avoid the fart can civic sound....the kind that sounds like the car should be flying but it goes by at 30 and barely accelerating.

I'd recommend the Top Speed Y-back, I've had mine over 3 years and it's been very good.

How is the Top Speed in regard to interior tone? My Stillen drones like crazy from 1700-2100rpm under load and drives me crazy. The rest of the time it isn't to bad.

I love my Tanabe axle-back coupled with HFC's and upgraded intakes

The "drone-zone" is 1500-1800 w/ the TopSpeed, not really obtrusive though IMO, if it was still @2100 rpm that would get annoying since I'm in that range much more often then 1800 or less.

So i was really debating buying that exact topspeed exhaust from ebay, before I do is there any problems with it? is it better then a muffler delete? how does it sound compared to stock/ other exhausts

I have the Top Speed also and have to say for the price am enjoying it. Wife approves which is a plus.

I also have the Top Speed on my car and so far I'm really enjoying it. It has a deep tone but not obnoxious. I recommend getting the beveled tips.

There are a lot of options for exhausts for the G. You just need to determine the balance of sound, cost, and tips.

I have the Invidia and love it. Definitely not a loud exhaust, at least not from inside the car, but sounds a lot better than stock. At $800 shipped I think it's the next cheapest option over the Top Speed.

That's a great price on the Top Speed Y-back. I trust blnewt's assessment. If I'm not mistaken, he purchased his early on and they have continued to make improvements since that time.

I prefer this Y-back over say the Tannabe because it increases the size of the tubing from the Y-Pipe back (60mm all the way through = 2.3622 inches). Most Axlebacks bolt up to the resonators, which on the stock setup appear to taper down to 1 7/8" where they exit and enter the axleback.

Is there a better sound clip than the one offered in their ad? I ask because they state "These Sound Clips Video's are from G37 Coupe the sound for Sedan is similar."

The coupe uses a single muffler with dual outlets, so I don't see how it will sound similar to the sedan's dual muffler setup. Am I missing something?

If I'm not mistaken, 60mm is the same size tubing used by Invidia. They also include the X-pipe to replace our Y-Pipe, but I believe many have already argued that the Y-Pipe is not the bottleneck on the sedan.

Anyone know how the TopSpeed would hold up in Minnesota winters?

Actually when I got mine 3.5 yrs ago they were very good, then had a pretty serious setback, they went from nice quality rolled/beveled tips to very cheap-looking, jagged thin walled straight tips. Most of the guys that bought those either sold them, or installed new tips since they looked so poor. The sound has always been very good though, and in the last year or so they've sold mostly the beveled tip set so they're back in good standing.

Whatever you do make SURE you get the beveled tip version as I still see the straight tip set come up on ebay sometimes.

Thanks blnewt.

Are the tips shown in the pics provided in the eBay listing the beveled ones?



Also, any thoughts on the comments they inserted related to the installation? Why would this setup be any more difficult to install compared to the others:

example:

You tighten the nuts&bolts on the exhaust on one side and move on to the other side the exhaust on left and right will not line up evenly and will be off in position.

Please tighten the nuts&bolts in rotation, right -> left -> right -> left and adjust the position of exhaust & exhaust hangers before tighten both side exhaust nuts&bolts.

For best results have a helper to stand behind the rear of your car to visually direct you to perfect installation.

Exhaust delete, hi-flo cats, leave the resonators?
