Im new to posting here and have only had the 2004 coupe cambio for about 2 months and the modding bug has gotten me. I'm not however new the eccentricities of working on all things Italian (Long time Ducati owner...).

I've seen many writeups on virtures of Larini vs Tubi back boxes alone, those paired with X-pipes, and the occasional secondary cat delete. I need my car to not be obnoxiously loud as it is a daily driver (I have the bike for being obnoxious, hehe), but I do want to hear some more beautiful motor sounds as well as getting more HP as efficiently as possible. When looking at the numbers, it appears that the biggest gains are from bypassing the secondary cats and resonator section. It seems the factory back boxes, while quiet, are fairly efficient.

So, what I'm asking is, has anyone tried deleting the secondary cats and doing an X-pipe while retaining the factory exhaust? It would seem this would be a healthy compromise of performance and sound, but I haven't seen anyone try this- it seems everyone either does the basic (back boxes) or the full monty.

Any help would be great here, and if nobody has tried it, I may just suck it up and go for it.

By the way, I just wired up the DBWEM, and damn does it make HUGE difference! Thanks Jeff.

Maserati GT Coupe & Spider Secondary Catbypass Pipe $1,175

I did the 2nd catbypass on my 2006 gransport will keeping my stock cans. I like the fact that I can control the sport option with the exhaust however it is now loud either way. I do like the sound and the power gain. I also like the stock GS can tips. Let me know if you have any questions. also I got the price down to 1000 even.

based on my experiences with a standard coupe/2004 as well, I'd start with the mufflers and go from there. The tubi or larini alone would make a nice difference.

We've tried just about every option / combination. Feel free to call me if you'd like to discuss the differences. With exhaust, it's important to spend the time up front to get the results you're after.

Best Regards,
