Haven't seen anybody with this dual 2 1/2" setup yet. Pacesetter headers, hiflow cats and Flowmaster 10 series single chamber mufflers and X pipe. Seen alot of 40 and 50 series, but no 10 series. Person at the muffler shop said I would lose a lot of low end torque. Are they right? If they are what can I do?

Thanks in advance

 

I have the 40 series and I didn't notice a a very big loss at all, but then again I definitly didn't notice a gain either. I believe that flowmaster has a great deep sound that many truck lovers want. But it does not deliver on the power gains they claim. If your looking for something to give you a little more low end, stick with magnaflow, gibson or banks. Theres a few others but thats what alot of people on here are running.

 

Well to be quite honest I wasn't really expecting to gain a whole lot ( bigger plans in the works for that.) What I'm worried about is, am I opening up the exhaust too much right now? Not being able to get the truck moving(because of the loss of low end torque) without having to go WOT would be kinda stupid.

 

From everyone I've talked too, seems FM's loose low end torque. I'd go with Mag, Borla, Banks if you want to keep or increase the low-end.
