Best Exhaust Combo??
Hey everyone I am getting ready to buy a full exhaust for my 99 Vette. I want something that sounds crisp and mean. I was thinking about getting some TPIS LTs, Bassani X, and a Borla xr1 muffler system. Anyone have this setup or recommend a nice race sounding :rolleyes: exhaust?

If you want performance and sound, the Borla XR-1 is the way to go. It flows the best and has the highest HP gain, but it is not street legal. it idles at around 96 db's and hits 110db's at WOT. Federal guideline is 95db's max, which is also California law. I am a little biased since I work at Borla, but facts are facts!!

What is the internal shape and flow direction of the Borla Xr1 muffler for a C5? I know most of the xr1s are a bullet design with straight through plumbing, the C5 has inlets and outlets located on the same side. Are there any pics of the inside of a XR1 for a C5?

Re: Best Exhaust Combo?? (ric'sblack86)
How does the XR1 compare to SLP's "LoudMouth" exhaust and the B&B PRT systems?
I'm going to buy one of the three in the next few months, but I want to know more about them.
Which one is loudest? Which one resonates the most? Which has most HP gain?
Anyone have sound clips of them installed??

Re: Best Exhaust Combo??
Are the Borla Xr1s emission legal and do they have a single Xr1 race muffler in the center or is it a resonator? Thanks in advance!!

BTW how do they sound with TPIS long tubes and no cats? :smash:

You can't do the Borla Xr1 and the X unless you remove the Cats. I was thinking the same thing when I bought my System. Headers and Xr1 will make your car real loud

Just a footnote, John Lingenfelter ran a 9.60 in Dallas last weekend in his 650hp street legal C-5. He was using our Titanium system. He said that the Borla Titanium exhaust system was the best flowing system to handle the output of those 650 ponies.

Re: Best Exhaust Combo?? (EuG)
Another thought, we are considering changing the XR-1's to have 4 large round tips coming out the back, pretty much filling up the space. Would appreciate any feedback from forum members. This would not change the flow, sound or hp gains...mainly cosmetic.

Re: Best Exhaust Combo?? (TWC5)
Do the high-flow cats make the xr1 louder?
I can’t imagine what it would be like w/o cats. Probably too much at that point :eek:
Howabout LT headers?

Re: Best Exhaust Combo?? (Quake)
Not inexpensive...list on the Titanium system is $2,499.99 but the street price may be less. It is the same performance and sound as our stock C-5 unit, but half the weight.
