I have car booked in with Lohen to fit a stock cat back system on 29th May…. So will report back if the noise is significantly reduced…… if I am still not happy, I will ask Lohen to put the stock manifold back on and pair it with my Milltek Cat Back. This combination I know sounds great and I have had no complaints.

It is funny as the car is at its most loud around 3500-4000 Revs…. Which is the where I spend most of my time in 6th gear on the motorway….. At non motorway speeds the car sound fantastic with the full system you get loads of growl, pops and burble, not forgetting the noticeable increase in mid range pulling power.

Lohen did comment that modified cylinder heads and cams can add significantly to the car noise level so I am sure some of your extra cabin noise will be coming from your revised head work.

IMHO I would avoid the JCW cat back, when Roland (GTT) did a test of back pressure, the JCW exhaust did not perform well…. in fact it was worst than stock with Milltek being the best. I also think that the JCW will not be any quieter than the Milltek.

Cheers

The stock exhaust will do the job- how do I know? I have done the same since I fitted my Janspeed mani +1320 cam + RMW head
