I have no popping.

 

I just added a cheap SI/DO thrush to mine,about 20 inch extensions on it.Like the sound but pretty loud inside at some rpm's

 

I'm not dignifying this with a response....



Its all about exhaust scavenging... I just orderd my Hooker Max Flo.. should be on this weekend. Cant wait to get the powahs back

 

Thats not what you said in an earlier response when you said "a NA engine needs backpressure.... guess these guys dont know that". The faster you get the exhaust out of the motor the better, right. Then why would someone want back pressure pushing the exhaust back towards the cylinders. Back pressure helps with emissions and thats about it. 2 strokes need back pressure in order to make power 4 strokes don't.

 

lmao.... backpressure helps close your valves bro. Bent valves are often found in engines with no backpressure. also you need back pressure to keep the exhaust from pulling good air/fuel mixture out the exhaust when the exhaust valve and intake valve are open at the same time



lemme ask this.. how old are you?

 

i had a si/do muffler it was installed right above the axle. the dual tips grew on me so i decided to cut them off and i went ahead and cut off the muffler to try out straight piped.
now i have the y pipe to a long pipe dumped w. a turndown right before the axle where the muffler was.
it sounds great is all i can say, the some may say its obnoxious but i love it,
and it absolutely SCREAMS at WOT !!!!!

 

23.

 

thank for the confirmation of payment of boost to my confidence

 

*shakes head*


High exhaust gas velocities, WTF!

 

so r yall sayin for an 04 to 08 f150 that u can take the muffler off the cat for a louder sound and not have issues or problems with the truck by doing so???

 

Yup im confused too

 

You can do that to any truck.. of any make & model, but you will lose low end power. If you delete the muffler & run the tailpipe out it wont be a bad loss.

 

short and simple...thats the way we like it,lol.so putting my thrush on with very little after it wont hurt either!

 

glasspacks ftl..... get a real muffler... more power, better sounds, less hillrod
