Will this set up have enough backpressure I dont want to lose to much bottom end torqe. I have ASM Headers allready installed Im getting dual 2 1/2 into a magnaflow muffler dual 2 1/2 out the back with 18"x4" tips. I am running stock cats this is going on a 03 silverado 5.3.
Don't know much about back-pressure..........but geez :eek:
.....think those tips will be big enough?
which muffler from magnaflow. is it one of the hd muffs. if so you will be fine. 4" tips :eek:
Larger tips than the rest of your pipe is a good idea because it creates some resonace and a nicer sound, but 4" is a bit overkill, 3" might be a little better idea.
I'd go with some 2.25" piping.
I drove my truck around for a bit with open exhaust, on holy shit, I could hardly burn out in first, normall I can burn out at will in first and continue in second, not without exhaust.
just a thought,

Um, what's your question now? Sounds like your setup is already done...Quote:

The headers are on not the exaust. So it sounds like everyone thinks the tips are to big which would you use. The muffler is a 5X11X22" body 2 1/2 in & out PART#14568. I want my truck to run mid 13s along with the mods I have and Volant cold air, Electric fans, TT2600, 3.90 gears, And Im thinking the same comp cam 02 Denali has. I am hopeing that will get me there. Oh yea some Drag radials and TB spacer. HaHa. I appreciate youre advice.Quote:

Man my wife just got home and I had her lay under the Truck holding the Exaust Tips up there they look Bad Ass. Do you think I should really go with 3" tips it seams they would look small.
Yeah, I don't like tips myself. I hide the tailpipes behind the bumper a la old Cadillacs/TownCars. Plus it limits resonation too. Tips act like a megaphone only.Quote:

I think it's going to take a bit more than the 5.3 to get you into the 13s all motor. I like 02's cam but it lacks on the lift and could use a more aggressive lobe IMO. Basically I think there is better stuff out there on the custom end from Comp. Allen is a Comp dealer soooo... find out which lobes you prefer and have a cam ground from there.
An LS1 or 6.0 swap would probably get you there with more ease.
Oh yes, I have the similar muffler in my attic to install... DI/DO Magnaflow w/ built in X-pipe. :smile:
Hahaha I love it when the wives get involved!Quote:
