Need some advices on exhaust mod

[murcod]

Someone said the Borla system drones (in another post) IIRC?

I think the RRM system would be LOUD as it only has the one central resonator/ muffler. (it would be saving them quite a few $$$ on production costs too!)

Here's that article on the RRM mods - not quite what I remembered as they did get gains (but had the full RRM kit - induction, piggyback ECU, lightweight pulley and exhaust.)

$1,500 for less than a second gained in 0-100 exceleration, no thanks. I could build a DIY supercharger kit for that much money.

i think i will just do exterior mods then......not worth the price to get the minimal gain that's not even noticeable.....

I think youd be better off straight piping the stock exhaust and putting in a highflow cat in. I presume youd get similar power/sound increases to the rrm catback for 1/4 the price. Most places will defect a car with no rear silencers.

This is essentially how the rrm kit appears to work.
