If the plugs need gapping you will soon know however won't do the car any harm if they breakdown.Given that you are going to have to re-gap your plugs prior to a custom tune you may as well do it anyways Link to comment Share on other sites More sharing options...

This was a better option than $950-995 from a business .Can anyone tell me what the T sounds like with the centre muffler removed as HPF has suggested it when the custom tune is done .

You will also get a burble when backing off the accelerator. This will accentuated if you go for straight through pipes as opposed to installing a couple of hotdogs. Some have reported that pipes only cause a bit of droning @ cruise.Why did HPF suggest you remove the centre muffler, was it just for the note?Given that the stock cat is the restriction I wouldn't of thought removing the centre muffler would make any difference to the flow rate of the exhaust.

There are gains to be had by doing it. Link to comment Share on other sites More sharing options...
