Well im not 100% on the rules when discussing product faults or companies, so mods if you see fit get rid of this bit.

We have used lukey mufflers before and it is our opinion that they are of an inferior quality. The systems (as in pre-fab systems) they make are even worse, they jsut dont have the same level of finish as other brands like X-force and redback.

The Lukey mufflers are all owned and manufactured in the US by walker. in our opinion they are outdated technologically, although they are starting to catch up now. But the mufflers seem to have a shorter life (in response to the complaint about redback ones, any muffler would have problems with those conditions) and they never seem to be as "good" in our views.

My LJ GTR exhaust system starts with a set of extractors going into a 2 1/4 pipe with only the rear XU1 muffler. It sounds great. Really changes note when approaching 3000 rpm's. No hotdog or middle muffler. The motor is very similar to XU1 spec. which gives it the typical torana exhaust sound. However, I would listen to orangeLJ as he is in the exhaust business. Here's a photo,

ohh and on that note, i will add we can get a front resonator specifically pressed to XU-1 spec. BUT i think they are real pricey, but will find out as we are getting one done in the next few weeks to fit my old mans XU-1 (which is currently getting paint) no one actually makes a front resonator to XU-1 spec anymore!

When I had my 4 door LC almost 30 years ago, I ran a dual 2" system on the 161.

The extractors were cut off at the last 2 into 1 joiner so that the front 3 cylinders ran into one pipe and the rear 3 ran into the other, with no crossover pipe. There was a single big offset style muffler on each side at the rear, but due to the fuel tank location, the mufflers were installed asymmetrically to ensure the outlets were symmetrical as they exited under the back valance.

The exhaust system really screwed up the carburettor mixture, but it sure sounded interesting.

Those were the days! All noise, no horsepower. I used to get a lift to work during my apprenticeship from a guy with a "comb-over" He was 30 going on 18. His car was a XR Falcon, with a stock 6 except for extractors and twin 2" back.
Barked its guts out and went nowhere. 3 on the tree too. He used to "blip" the throttle before he turned it off to "build up compression" for the next start.
