I read the reviews of this being loud and thought people were being fussy... The truth is its brutal!

I'm used to loud sports exhausts my other car is a 92 skyline GTR but this is in a different league!

I originally thought the issue was the lack of resonator box after the CAT. But it appears the issue is the back box design. The second tail pipe appears to have simply been joined on to the single exit back box. This results in almost the entire gas flow taking path of least resistance, bypassing the baffles and coming out the left pipe. Although this gives a nice subaru type noise at idle (I presume because of diferent volume and frequency from each pipe) it leads to a very noisy practically unsilenced exhaust when driving and a very severe resonance issue at 3000-3700rpm.

I use the car a great deal and frequently go touring in summer and 1200 mile round trips on motorway are not much fun! Conversation is impossible and forget about the stereo!
The problem does not improve with age in fact if anything it gets worse as the back box cokes up more goes through left pipe.
You may think you can get used to it but after a year its my hearing going not the exhaust getting quiter!

I have added a large silencer in place of CAT which has moved the resonance RPM range a bit but not helped much.
Another small point, a support bracket for second tail pipe would help the sit of the exhaust but this isn't difficult to fabricate DIY!

Its a great shame as the construction fit and value are superb. If they could alter the design of the back box to give a more even flow it would be a great product. I'm sure the single exit system is a lot better. Rating: 2 of 5 Stars! [2 of 5 Stars!]
