top speed pro 1
 

hows this exhaust...its so cheap its 500 bucks i know it sounds good but what about quality and hardware included? anybody ?

You pay for what you get. It sounds good on YouTube , but there are also quality issues as posted by members here. Invidia exhaust is a little more pricey at 800 but it's a proven brand.

If I'm not mistaken they are replica of tanabe exhaust, correct me if I'm wrong

Its good. I bought one knowing it needed a fitment tweak but at $450 who cares, its a easy fix.

I currently run the tanabe exhaust and they sound somewhat similar. The top speed one doesn't sound as deep.

They produced a bad batch but have since fixed the problem. I unfortunately managed to get a bad one, but had it fuxed for 20.00. The ONLY annoyance is how far the tips stick out the back. I get nothing but compliments on the sound
