I currently have an 89 mustang w/a 5.3/4l60e swap. Seems to have too much drone at idle. i want to be able to hear that aggressive cam!

mods: 285lr hr13 comp cam (235/243 .614/.624 @113lsa 13* overlap)
PRC dual springs
7.4 chromoly pushrods
truck intake
virgin 706 heads
P&P stock TB (DBC)
2.5 H pipe with flowmaster 44s
2.73 trac-loc
4l60e w/red clutches, beast sunshell, HD2 shift kit and larger band

I was recommended a 3 inch Y pipe with a dynomax race bullet. What do you guys think? All recommendations are welcome!!

This is my current sounds clip:

Run the pipes out the back of the car where they belong. Problem solved

Keep it dual, no Y. Run a pair of the largest straight-through mufflers you can fit. Get the exhaust out from under the car, run it out the back or sides.


Also, 4-lug wheels? Still running the small rear-end?

Get a couple of Dynomax Ultra Flo Welded Mufflers, and again run the exhaust out the back or sides.

They made plenty of 8.8s with 4 lug axles. 5 lug didnt come until 1994.

Went with dumped straight pipe using the existing H-pipe

Looks and sounds good. Not to derail the thread, but do you recall the application the upper and lower radiator hoses came from to fit your setup? It looks like you are still running the mustang radiator. I am almost done with a very similar build.

They came from a 2002 Silverado. We used the upper rad hose from the silverado and put it on the lower rad hose in the mustang. Then we used the lower rad hose from the silverado and cut it to size for the upper part of rad.

silverado upper = mustang lower
silverado lower = mustang upper

just cut to size.
