will a type r muffler give me hp

i got a jdm type r muffler on my 98 rs w/4-1 dc and 2 1/2 piping sounds really good when its alittle worm but it crackles when i first get going am i getting better hp then stock and should i jus go for another muff.i like the muffler part not talking about the tip, i want one that looks like the RS-R one any input will b appreciated thank you and is rsr a good co

Do you have the piping as well? Because the muffler just welded onto your stock piping won't give you any gains. You need the 2 1/2 inch piping from the cat back to match the muffler.

yes sir i do have 2 1/2 piping kinda sounds halo and no resinator

my friend has 2 RSR canisters on his g35 coupe , they sound REALLY good !! you can hear hm from neighborhoods away !! i was wondering if the RSR exhaust for the tegs are good myself ...

Are you talking about the R*SR GT2, or the Ex-Mag? Because, the Ex-Mag looks almost exactly like the stock Type-R exhaust and is just as quiet.

hey thanks 95teg gonna look into the meg ex forgot all about that one thanks nice lookin
