- Race Bullet 24215 Exhaust Resonator

I needed to replace the muffler on my f150. Purchased this cause I wanted to improve the sounds of the truck. Appears to be good quality, the sound is amazing no real drone in the car, but the real deep rich V8 sound that’s not crazy loud. Highly recommend

I have a 2004 Audi TT 225 with a 3" turbo back. The drone and loudness was driving me nuts. The local parts store guy told me that the only way to get it quiet was to put the stock exhaust back on. Well, I didn't want to do that, so I tried the Vibrant Ultra-Quiet Resonator with 3" inlet and outlet. It actually made the sound worse than a straight pipe. So I thought, what the heck, let me try this Dynomax with 2.5" inlet and outlet. (The stock exhaust on the TT is 2.5".) Using 3" ID to 2.5" OD adapters on each end, it fit perfectly as a mid exhaust resonator. And it quieted the noise way down. Drone is completely gone unless I really get on it between 3000 and 4000 rpm, but cruising at highway speeds it's almost as quiet as stock, but not quite. It purrs at idle and sounds nice and throaty with a little spirited driving. At half the price of a 3" resonator, this is a steal! Plus it really works.

Bought this resonator for my 2006 Acura TL to replace the oem one that came with the car. I also deleted the mid muffler as well as the rear two. Car sounds great!

Put it on my 2007 Acura TL type s and deleted the 3rd cat mid muffler and rear mufflers and it’s perfect it’s loud but doesn’t have any of that annoying v6 rasp cause of this resonator

Came in great packaging, very nice quality. Also sounds amazing. I have this on my Acura tl and it sounds very aggressive, does have droning while cruising.

It gave my Titan an aggresive and deep tone, I little cab drone at highway speed but you get that with almost every setup on these Nissan Titans, I would recommend this muffler for anybody looking to have a throaty exhaust tone without spending too much, I took my truck to a muffler shop and they charged me tweenty buck to weld the muffler in place since I had a Y pipe already weld from a previous muffler swap.

Great Sound deep idle on my system: 2014 Dodge Charger, 5.7 hemi V8, straight mandrel bent 2.5 inch pipes. no cats, no mid muffler. Mounted behind my axel. Btw. 2.5 pipes slip into the muffler. Clamp or weld to install. Made the straight pipes more mellow & deep sounding. But loud if you jump on it Have a tune on my stock engine by HemiFever ... performance difference is incredible

This res sounds great with a Mid muffler delete on the Acura Tl 07-08. Between 1K-4.5K rpm it sound perfect. Not quiet but its not going to be annoying to the neighborhood. I recomend this 100%, the sound you get for the money you pay is amazing.
