Sheesh. What was your setup. Just the axle back or you had other exhaust changes as well?

I had to get a tune to fix my a/f ratio because the fuel smell was pretty bad, after the tune I barely ever smell it. The wind has to blow at 10 degrees north with my windows open for me to smell it now. Also I can shoot flames now!

I feel like this is too opinionated, it might sound too loud/droney for you but the next person might think it is really quiet. Just how one perceives sound.

Agreed. Had I seen that many reviews like that. I wouldn't have even considered. Good thing I didn't.

Most reviews I see are too loud for the gf or wife, or too loud for the actual person, but Imo everybody has their own preferences of sound, one person might like the louder sound while another just wants a little increase from stock.

Was this the same Top Speed exhaust as the Manzo/Beluga? I thought I remember seeing a straight pipe option without any cans from Top Speed. I could see that system being loud in comparison.

I think the best way to put this all to rest is going to be logging frequency response data with a dB meter under various engine load scenarios. Perhaps an acceleration run, and then steady speed at 45, 80 etc.

I have the equipment to do this but haven't bit the bullet yet. If I do, I'll log some dB response data. If there is any drone we should be able to see where it lies in the frequency spectrum and how intense it is in comparison to stock.

Unless anyone else has an SPL meter or calibrated mic?


Edit: This is the straight pipe Top Speed system I'm referring to:


This is not the one you have, correct?

That sounds like a great idea. But that would mean one person would have to 3 separate axle backs, and take one for the team. LOL

These are the ones I had, way to Fing loud!!

G-thirty7X

True!

If I did this I would just log the stock system and then whichever axle back I chose to go with.

It wouldn't be an optimal comparison without all 3 axle back systems, but it should give us a good idea. Besides knowing exactly how much material each company packs their cans with - all 3 appear to be the same can diameter/length.

Those were not even considered. They are brutally loud


What is Market Outlet? I think you may have got the authentic Chinese version...



I would be down had I been closer. I think it does come down to the material it was packed with.

This is more similar to the AAM short tails.

Pretty happy with my Beluga axle back - I think I paid around $160-$180 from eBay. I see it on there now for some ridiculous amount, or "best offer". ???

Nice deep sound. Has a bit of drone at low rpms, but it's at a very narrow band of rpms - basically when pulling away from a stop. No drone while regular driving.

I have a question I had the top speed axleback on my g37 coupe, now I have a sedan and was wondering if the y back will be as loud as the coupe axleback?? I liked how loud it was and didn't mind it at all always got compliments everywhere I went

Where'd you get it for 160-180$? Everywhere is 250$ or so.

Landshark

you're right, it was around $250. i keep confusing it with something else i bought around t he same time ...
