hi, someone once told me that if i got the borla s-type muffler it would sound very similar to the roush OR muffler. my question is. does the s-type only come in si/so or is there a si/do. and if they only come in si/so i could still have 2 tips, i would just need a y pipe after the muffler or something?? and would it affect sound or performance?
thanks alot
alex

 

how about true duals with two s-types!

 

yeah with an x-pipe and two mag high flow cats and some 4 inch tips.
ill do it if you give me a one of them mufflers, otherwise thats a pricey set up for a kid that just graduated highschool. are there any other mufflers that arent 180 a piece that would sound as good as those would, that are maybe a little cheaper?
but that is basically the setup i want with the two tips exiting lightning style before rear tire. think this will sound ok, i have the 4.6.

 

also, how much a difference do the high flow cats make, ill probably hold off on those until i get some more money.
thanks.

 

Search borla stinger on youtube. That muffler is the S-Type on a mustang. I had them on mine before I sold it. No drone, but very loud. I believe 103db's on a stock mustang. You can put a Y pipe after muffer. High flows will nearly double the sound.

 

Dynomax bullets are excellent, loud mufflers and you can get them for 40 bucks each. true duals with bullets will sound incredible.
