I have been to Lambros in 2001 to fit a turbo back full exhaust system for my rexi and I was really happy about it. The quality, worksmanship, service and finally the sound was awsome!. I did try other exhaust brands but nothing beats Lambros Exhaust. Anyways I did go back again for the second time in 12 yrs and nothing has been changed. The owner Lambros was there at 7:30am (this is the time I went there on sat) even before the workers came. He offered me a free cafe coffee from across the road and made feel like someone I knew for a long time. He was the same man 12 yrs ago.
He gave me a good price for the kind of muffler I wanted and chucked in free tip.
After waiting about an hour, the job was finally done and went for a test drive. The sound was really good but it was a bit loud (since it's a VW) for me so went back and told Lambros about it. He then with a smile on his face said "No worries mate, we'll do something about it" dont worry!. then the boys started to add bits and pieces (like new resonator and silencer) and the sound was perfect!. I couldn't want more!.
He then shook my hand and said "It's all yours mate!".
If you want to add or fix your muffler just go to the well known specialist and don't gamble and take it to a corner shop or some muffler places on internet. You will regret it big time!.
