Invidia q300? r400? or MXP SP? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Tea · 10-29-2021, 12:36 AM

Hi guys, hope you all had a wonderful day. I am recently looking to get an exhaust system. I have a full stock system right now and this exhaust would be the first step.
For the plan, I probably would go with a catted header and an over pipe in the future but not too soon. Another thing is that I use my BRZ to daily drive a lot so it would be best if the exhaust has no drone.
I did some research and eventually narrowed the choice down to Invidia q300, r400, and MXP SP. Love the tone and they are also not too loud. Does anyone who owned one of these exhaust systems can provide some feedback like how loud they would be relative to the stock, and would be a lot of noise in the cabin?
I know they're probably already exist a few forums asking about q300 and r400, but I did not find their comparison with MXP SP. Any comment would be appreciated! Thank you guys!

YouTube search for exhaust vids. There are tons. I have q300 and at idle it’s like stock but good sound when on it. Catless header and stock FP.

I have catless headers and a q300 and it's offensive to my neighbours, wife, kids and dogs on cold start.

(Can be easily remedied) by giving a tiny bit of throttle to raise revs above 1500.

At idle it's quiet and deep.

At highway speed it's noisy in cabin but not so loud one has to shout.

Outside, driving normally it's loud enough to attract attention, which I don't like. Like most cars with a loud exhaust, when I floor it, I get looks of 'wanker'.

MXP-SP all the way. Also look at CSG Touring catback which is made by MXP.

Yeah my tune eliminated the cold start so it’s limited to 1100 rpm. Still loud but not insane.

Nice run!

Are you still on the stock front pipe, or which one do you have? Always thought the Q300 was quiet on these

Thanks mate. The exhaust shop made one up for me to eliminate the second cat.
