Default Another muffler delete video for those thinking about it

got a little time today. couldn't push the car all the way, its cold out here and didnt want something to happen.

the crushed pipe on the y pipe in the back was replaced with with a full pipe. it sounds a bit more "cammed" at idle now. sounds better in person though. the 2nd intake sounds sweet at WOT.

So did you have done exactly? Did you take it to a muffler shop and just have them cut off the muffler and weld in a straight pipe? are the secondary cats still in place ?

this is a generic pic of the oem isf exhaust. you see the y pipe that goes into the two rear mufflers. there is a bend there. i did a 2.5 from the resonator all the way out.


secondary cats and resonator still in place. after listening to Vijay's set up on here with the secondary cats gone, might be a fun little mod for the summer time. not sure yet, i do enjoy the WOT sound a lot. people around here love it. its like the exhaust quiets up and all you hear is big rush of air sucking in the car.

the place i took it to was really nice and we both sat down and he actually listened to my ideas and made mock ups and really involved me the whole process which after i tipped him, came out to about 170 bucks. it was suppose to be more but his whole team was excited to work on this car because they never seen or even heard what the ISF was lol.

the main goal was to just have both pipes using piece each side, no cuts. and also to hang lower than my previous joe z exhaust a whole 2 inches so it a can actually been seen from the back when driving.

Will try to get a video of secondary cats deleted also dude. Sorry about this weekend, weather was bad and couldn't have anyone stand outside to video it. In the meantime on my YT channel there is a video of interior sound at regular throttle. Did you want a video from the outside normal throttle as well?

no problem. same here with bad weather this weekend as well. im actually not concerned with interior drone . it will never be as bad as having no exhaust from the headers lol.

just like a normal take off driving down the road. i want to see if it keeps that low rpm muscle sound that i was looking for with this set up.

thanks bro, might join you on the secondary cats

Thank you for explaining that buddy. I am dying to make the car a bit louder but dont want droning. I am assuming the drone is pretty similar to stock . What do you think?
