Tunnel ram or no tunnel ram...
I got rid of European style mufflers and put Spintech 3000 on my car. This change made the car idle better and cruising seems more stable. Did minor ifr tweaks and it seems to run very good. Too bad I don’t have enough time to work on my own car this year. Hopefully in about 2 months it will be better.
I like the new sound! Old muffler before welding new ones for comparison. Amazingly the new ones are quieter on idle and at low rpm driving. Wot is another story…
