[Teg RS]

Is it worth going with Type R muffer for a RS? Are there much HP gain from doing so?

How much is the Thermal Research Exhaust goes for and where do I buy them?

 

[junglistgsr]

it would flow a little better but its still chambered so it wouldnt help that much over stock if you dont have many mods and without larger piping it really wont help much

Its a waste of money
