I am currently looking at a Top Speed Pro 1 exhaust for my G37S sedan. I love the sound and they have finally come back in stock.

My question is, Has any one had one of these long term? ecspecially in a snowy state like Wisconsin or Minnesota. How did it hold up? did it have rust issue?

Also is there any major droning? Any Reviews would be helpful

I am also Considering the Invidia Q300, though i think its to quiet for my taste, or the Tanabe Medallion axle back. My budget is limited, so the top speed fit the bill for that, but i cant have it obnoxious because of the wife and child.

Thanks for Any help

 

The passanger side of the midpipe is all rusted out. Had on it on for like 4 years now. I live in CT. Also not sure if they fixed the issue of the mipipe hitting the brace. I ended up having to remove the brace since it was getting in the way.

 

I've had mine on for 3 - 4 years now in MD; we use salt on the roads for winter. It's held up perfectly fine. It's a nice bump over stock but an after market Y pipe really brings out the tone of it. I picked up a eBay Y-pipe for $100.00 and paired with the Top Speed it sounded great.


I didn't have fitment issues. I used a jack to raise the Y-pipe to Mid-pipe flange section and tightened down my bolts. Seems to help with some sag others have experienced.

Thats good to know, i am looking at the Pro 1 that comes with the Y pipe.

Does yours drone at all?

 

It does a very little bit from 2500-3000. I have Test pipes now that required additional resonators welded in. After the test pipes it was just too much for a DD. If you do the Top speed+ ebay Y pipe combo, I can promise you that you will like it if the Invidia system is also on your list.

To add perspective, I'm a 30 yr. old married man with a child so my tolerance for drone and rasp is non-existent. Best part about the set-up in the video is the exhaust was only there when you were laying into it. Moderate throttle below 3k RPMs is slighly louder and growlier than stock. Above 3k it definitely comes to life but its not an absolute screamer like Motordyne. If I had to place it somewhere, it's tone and volume is between the Invidia 300 and Fast Intentions.

 

Get yourself a quality exhaust, it will be worth it in the long run. You can always sell it down the road and recoup 60-70% of what you paid.
