Summit RacingSummit Racing Verified Purchase

Had this very same Flowmaster series 10 (1 Chamber) on my "97 mustang GT back in the day, factory exhaust was horrible on that car with 6 cats, yes 6 cats on the car, I did not want to mess with O2 sensors so I left all 6 cats in place, installed these & dumped the pipes.. Sounded awesome, made some heads turn for a 4.6 liter V8. Now I installed this pair on my 2010 Ford F-150 with 5.4 liter V8, I have a True dual exhaust set up 2 I did install 2 (1 chamber/ series 10) Flowmasters. On a cold start this these mufflers sound crazy loud, however when they warm up its a deeper tone. I do have 3" magna flow tips. cats are stock. Its a good buy not as loud as the glass packs that were removed off my truck to install these but not a bad tone. ...read more

Just the sound I was looking for. I had glass packs which were ok but these made all the difference in the world.

DEMON SPEEDING.

I bought 2 of these as well as a summit universal 3" x pipe kit and headers for my 81 camaro with a 468 bbc; .540/.540 226@ .50 cam; LS6 rectangular port heads; single plane intake and q-jets stage 3 quadrajet. Just mean sounding. Evil incarnate. I've raced a modified 99 ls1, a cammed performance heads 77 camaro with sidepipes, and a 0 somthing kawasaki 636 R not one of them could hear their car/bike during the race. I will buy these for every big block project i ever take up ...read more

2002 Dodge Ram 1500 4.7L

Summit RacingSummit Racing Verified Purchase

This muffler isn't all too loud on newer V8's even. The sound is just okay for me, as I'm used to a Dynomax bullet tone. This muffler would sound best on older V8's, preferably carbureted and bigger than 300 cubic inches. This muffler would also sound great on V8 powered vehicles of any kind that could be without a cat converter, however if not then newer V8's wouldn't really gain too much sound quality from these mufflers in my opinion. Three stars for my opinion. ...read more

Been wanting these bad boys for a while. Easy process; ordering , shipping , delivery. Actually delivered sooner than I expected. Waiting on cats before I can install . Will use summit racing for more performance parts.

The mufflers are loud, not as loud as I was expecting at idle, but they're as described. They're very raw sounding.

With no cats 10 series is extremely loud

Summit RacingSummit Racing Verified Purchase

I have them on a jeep that has a 2007 chevy 5.3 swapped in, it has magnaflow cats an sounds awesome. Decided to put them on my 68 camaro, it has long tube headers and h pipe with no cats. Very built, high compression, fuel injected 383. i swear it couldn't be much louder if it was just the headers. I like it, just extremely loud. I guess the 100 more hp and no cats is the reason there is so much difference from the jeep ...read more
