Transplanting 4A-GE SVT 20v to AE90. have some questions to ask

[scottwrx]

i got the twin muffler and think to install it to my car
i'm using blacktop.... this exhaust is design to svt right?
is it ok if i use to blacktop?
is it need difficult modification to be install to ae92?
right now already have mounting to place the twin muffler..
already use the twin muffler before but the noisy one, not the silent type..
both of the pipe come from the rear
the silent twin pipe, one of the pipe connected to rear and the other connected to side of the muffler right?
one of the muffler that this car currently use is prob already..
so, change the piping to single muffler but the shop doesnt do the good job..
the piping seen too small for the engine..to many backpresure and detonation
so, if i use the silent twin muffler, does it suitable with blacktop?
how much the shop will charge?
go to one shop, he want rm180++
another shop quote me rm300++
do u know where i can install this muffler with a cheaper price?

bro.. sorry for the late reply.. coz missed out... i m not sure how the ae92 piping ways, but if u wanna use, the cheapest way is to get a levin twin muffler, if u can use the full piping then u can cut and use the piping from the y seperator onwards... then save u head ache...
