Fits great, sounds awesome.
It’s been on the car for a few weeks now and I couldn’t be happier. Has a great sound not too loud, definitely a little louder than stock. The fit was perfect quality was great

A good starting point for roadmaster wagonexhaust.
I bought this kit to use on a 1996 Buick Roadmaster Wagon, so take that into account. Since they're both B-body Chevrolets, this kit is very close and provides a good starting point for a full cat-back exhaust. You'll need to modify the over axle and rear exhaust pieces to get it to fit correctly. Since I was in a hurry, I dumped it pre-axle and it sounds great, loud but not too droney. When I get some more time, I'll finish it as it's supposed to.

This is a really nice product for the price
Just had this system installed professionally at a local exhaust/fabrication shop. The shop owner (31 years experience) was impressed with the quality and ease of installation and the fact that the whole system was mandrel bent. Instead of using the included clamps he welded all the joints which makes for a tighter system . The system sounds great with almost no drone at highway speeds, mellow tone at part throttle and deep muscle car sound at WOT. Jegs, you've done a great job with this one !!

better than i expected
i recently had this exhaust put on my Roadmaster wagon, the only mod needed was to remove a trailer hitch i don't use. It looks and sounds great, plus she has more pep! Can't beat the price either.

1994 BUICK ROADMASTER ESTATE WAGON, IMPALA SOUND
Please keep in mind this exhaust is for an Impala Caprice and Roadmaster sedan, but it fits the wagon to a certain degree. The exhaust is about 6 inches short, so you have to get creative near the tips if you choose to use them. Also note the pipes are 2 1/2" as oppose to 2 1/4" and they are not flattened near the transmission cross member like the original, could be an issue if you lower your car. Everything works well with the exception of how it sits, the pipes need to be pulled upward some so that its hidden like the original exhaust. See pictures!! All in All I love the exhaust sounds good, I even brought the exhaust again to put on my 96 RMW which I'm working on next, I just have to figure out a way to tuck the exhaust better.

Nice Exhaust For The Price
I put this on my 1995 Roadmaster 2½ years ago. The only difficult part was getting the tailpipes over the axle and positioned properly. It took a little work to get them both tucked up tight by the gas tank.

What kind of sound will this system have? I’m looking for something to add a deep rumble but not too loud.
The Jegs 555-30410 exhaust will have a deep, turbo muffler sound.
