I have always had flowmasters on anything I have ever driven. I decided to take a chance on Magnaflow on my 90 RS. There is no way I will ever go back to Flowmaster. The shop put on a 3 inch Magnaflow cat, 3 inch intermediate pipe, and si/so Magnaflow muffler. The sound is amazing, a low gurgle at idle, quiet at cruising, and pretty loud and deep when accelerating. The car previously had dual exhaust with cherrybomb glasspacks and no cats (previous owner). Sounded like a darn tractor and couldnt hear the radio. Cliffnotes: -Flowmaster sucks -Keep your cat -Dual exhaust is overrated and does not fit.

nice. I like magnaflow. your right about the flowmaster. if on the highway I would have to yell at the passanger so they can hear me. I have a gmmg catback with a high flow cat and it. it is nice mellow tone at cruising but if you pass 2300 Rpm it starts to get loud. if i floor it wow it mean

It's all about personal preference here. Alot of people think that magnaflow is just too quiet.

A friend from work put a magnaflow catback on his truck and it's pretty quiet at idle and cruising but when he steps on it it really roars, it sounds great.

magnaflow with my mods was awsome!

Now--with no cats it very loud

yeesss and so does every swinging d!ck run a flowmaster...cars trucks mopeds you name it, i did the same thing on my 91 rs and i deff dont regret it. glad you liked it! only thiing now i need to do is get rid of that stupid crinkley pipe they put on for an intermediate!!

prolly make it a it louder also...but now im running hooker 2055's with this set up.

I plan on ordering the 2055s next month. Are you happy with the fitment, quality, etc. of these headers?

Did it change the volume or tone of the exhaust?

Is there a noticeable improvement on the butt-dyno?

if you check the sticky at the top of this page "those with hooker 2055's, come on in" then you can see how happy i was with fitment. butt dyno was awsome first time out. i dont believe that there is better quality for shorties than 2055s. the tone changed a bit too. different engines different sounds though i would think. the magnaflow cat back i put in a week or 2 after the headers and i liked the set up even more.

on a side note- exhaust is always an opinion on sound. i love the sounds of mine. and hated the performance of the flowmaster i took off.
